Perimeter Intruder Detection System(PIDS)
• The Perimeters in the main consist of a Perimeter wall 8 ft high with a concertina coil overhang of 1 and ½ ft.
• The existing perceived threat is that the Intruder will scale the wall to gain access to the require protection and Security zone facility; therefore specific
Electronic systems need to be designed to provide a stable Perimeter Intruder Detection System with a low false alarm rate
• The existing Perimeter Walls present some challengesas follows:
• 1. Built Up areas
• 2. General Public direct access to the Perimeter
• 3. Condition and application of the Physical Barrier protection
• 4. Environmental conditions
• 5. Broken perimeter wall and with gaps at places
To address the Security Requirement taking into consideration the existing parameters,
it is proposed to install the followingPerimeter Intruder Detection solution:
• 1. A Covert Radio Frequency Intruder Detection System to be buried between the
• Perimeter Wall and the Inner Access Perimeter Road.
• 2. A Secondary Active Infra Red Intruder Detection system to be located on the Airport
• side of the Inner Perimeter Access Road.
• 3. The Perimeter Intruder Detection System will be interfaced with a comprehensive CCTV
• surveillance system (each Perimeter Detection Zone will have a dedicated CCTV camera
• associated with it).
• The total CCTV/PIDS solution will be connected to a Main Control Room within the Permise

Lightning Kills and Destroy Your Valuable Assets
No lightningprotection systemis 100% effective.A systemdesigned in compliance with the
standard does not guarantee immunity from damage. Lightningprotection is an issue of
statisticalprobabilitiesand risk management. A system designed in compliance with the
standard should statistically reduce the risk to below a pre-determinedthreshold.The risk
management process provides a framework for this analysis. An effective lightning
protection systemneeds to control a variety of risks. While the current of the lightningflash
creates a number of electrical hazards, thermal and mechanical hazards also need to be
addressed. Risk to persons (and animals) include: • Direct flash • Step potential • Touch
potential• Side flash • Secondary effects:– asphyxiation from smoke or injury due to fire –
structural dangers such as falling masonry from point of strike – unsafe conditionssuch as
water ingress from roof penetrationscausing electricalor other hazards, failure or
malfunction of processes, equipment and safetysystemsRiskto structures& internal
equipment include: • Fire and/or explosion triggered by heat of lightningflash, its
attachment point or electricalarcing of lightning current within structures• Fire and/or
explosion triggered by ohmic heating of conductors or arcing due to melted conductors •
Puncturesof structure roofing due to plasma heat at lightningpoint of strike • Failure of
internal electrical and electronic systems • Mechanical damage including dislodged materials
at point of strike

Lightning Charge Threat to Human and Valuable Infrastructure
Atmospheric discharges are a powerful natural phenomenon. Lightning can reach a power of several hundred gigawatts and can have a destructive or disturbing effect on
electrical systems located miles away from the point where the lightning strikes.Damage caused by direct lightning strikes is generally serious, with large conomic consequences.
As an example, the electrical switchboard can catch fire, causing devastation of industrial equipment and even the building. The best and only way to avoid this is the installation
of an ELP.Atmospheric discharges can determine various phenomena in an electrical system, resulting both from direct and indirect lightning strikes.
Direct lightning strikes on lightning rods/conductors (LPS, Lightning Protection System) or external conductive elements (antennas, metallic pipes/guttering etc.).Galvanic
coupling When lightning strikes the lightning conductor or roof of an earthed building directly, the current flows to earth and through the power supply lines. The resistance of
the PE system, when dispersing the lightning current, causes an increase in the PE conductor up to several thousand volts (ohmic effect). On the other hand, the potential of the
active conductors remains at 230 V for the phases and zero for the neutral (remote potential of the transformer). The electrical equipment connected between the power supply
network and earth can break their isolation and some of the lightning current flows through them, resulting in damage.
Direct lightning strike on aerial power lines. Conductive coupling When lightning strikes a low voltage aerial power line, very strong currents flow through it, entering the
buildings it supplies and giving rise to large overvoltage surges. The large amount of energy entering directly into the system causes faults and failures of electrical or electronic
equipment connected to the power supply.
Indirect lightning strikes.Electromagnetic coupling The electromagnetic field created by atmospheric discharges in the vicinity of aerial electricity lines or electrical systems
generates an overvoltage surge in each loop of the circuit. The electricity lines incorporate loops since the neutral or PE is connected repeatedly to earth (every two or three
poles).
Even lightning striking the external protection system (LPS) creates a surge in the loops formed by the electrical system wiring.With a range of hundreds of yards or even miles, the
electromagnetic field generated in cloud lightning can create sudden voltage increases.In these cases the damage, less spectacular than in the previous cases, can still have a
permanent effect on the most sensitive electronic equipment such as computers, photocopiers and security and communications systems.
The following curve summarizes the cumulative frequency of the lightning strikes with respect to their intensity, according to the results of this enormous measuring campaign:
– 1.27% of the lightning strikes are greater than 100 kA

Conventional Lighnting Protection as per IEC62035
The Six Interdependent Disciplines that form the ProtectionPlan are:
Capture the lightning strike
Convey this energy to ground
Dissipate the energy into the grounding system
Bond all ground points together
Protect incoming AC power feeders with use of Surge Protection
Protect low-voltage data/telecommunications circuits with use of Surge Protection
The lightning protection materials to be used for this type of installation may be aluminum or
copper, within the allowances of NFPA® code 780. Some of the criteria for choosing one type
of material over another are as follows:
Materials to which lightning protection components are to be installed for compatibility;
aluminum on aluminum, copper on copper, etc.and Other Lightning protection components to
match existing lightning protection materials.Lightning protection components to match
existing lightning protection materials.

Selection of Right SurgeProtection and Installation is is your Hand (TECHNICAL AwareneSS)
Electrical circuits may be connected to ground (earth) for several reasons. Earthing serves as:
•Personal protection
•Property/ operational protection
•Potential grading earthing
•Electro-magnetic pulses protection
•Lightning protection
In mains powered equipment, exposed metal parts are connected to ground so that if, due to any fault conditions, a “line” supply voltage connection occurs to any
such conductive parts, the current flow will then be such that any protective equipment installed for either overload or “leakage” protection will operate and
disconnect the line voltage.
This is done to prevent harm resulting to the user from coming in contact with any such dangerous voltage in a situation where the user may, at the same time, also
come in contact with an object at ground/earth potential. Connection to ground also limits the build-up of static electricity when handling flammable products or
electrostatic-sensitive devices.
Earthing should include:
Low electrical resistance(Max1.00 Ohm)
Ability to conduct stable voltage,even at weather changes
Long life expectancy, i.e. high resistanceagainst corrosion

Surge is Danger Threat It’s Pick-up and Travel to System
Pulse/MicroSec (10/350,8/20&1.2/50) as per UL 1449 and IEC 61643-11
Surge protection devices suppress the excess voltage, divert it safely to the ground and prevents it
from causing any harm. Surge or Lightening Protector is designed to provide Line to Line protection
and Line to Ground protection.
Operating Voltage of the Surge or Lightening protector is greater than the normal operating voltage
of the device or system to be protected.
During the normal operating condition, the Surge or Lightening are non-functional as they provide a
high impedance path between Lines to Ground.

Surge Protection Installation for Individuall Equipments Safety
When SPDs are individually applied to services, as the
common mode surge
Current from the SPD "C" terminal to the local earth
reference via the earthing cable can create a potential
difference from the true earth potential. Further the local
earth references themselves may be at different potentials.
1.5 µH/m. A diverted surge current of 50 A/µs would create
an inductive voltage of 75 V/m. This inductive voltage adds
to the SPD limiting voltage
The power SPD will be connected to the mains plug/socket
local earth reference. The incomingserviceSPD1 and
outgoing service equipment SPD will be connected to
whatever local earth reference is provided. For the screened
cable SPDn the earth reference could be applied to the
cable
originatingend.

Surge Protection Installation for Multiple Equipments Safety
A surge reference equaliser does two things; it brings together all the
service SPDs by locating themin a single enclosure and provides a local
earth reference for all the SPD "C" terminals to directly connect the
common bonding point, or "star" connection has two external earth
reference
One from the power SPD mains plug/socket local earth reference and
the other from the screened cable remote earth reference. This means
that the diverted surge current can split between the power and
screened cable earth references.to avoid earth loops in normal
operation, one SPDn option is to make the screened cable
"C"connection to the common bonding point via an SPD with a
switching function, which maintains isolation during normal conditions
but provides a bond during the occurrence of a surge.
The surge reference equaliser is now called an MSPD, although there
may not be any SPDs in it,only SPCs giving the equivalent surge
functionality of the replaced SPDs.
MSPD for protecting power, antenna, telephone and Ethernet services
with warning lights for protection failure and missing earth connection.

Maximum Continuous Operating Voltage Uc is the maximum RMS voltage that may be continuously applied to the SPD's mode of protection e.g. phase to neutralmode. This is equivalent to the
SPD's rated peak voltage.
Temporary Overvoltage UT is the stated test value of momentary voltage increaseor overvoltage that the power SPD must withstand safely for a defined time.Temporary overvoltages,
typically lasting up to several seconds, usually
originate from switching operations or wiring faults (for example, sudden load rejection, single phase faults) as well as mains abnormalities such as ferro-resonance effects and harmonics.
Impulse Current Amp is defined by three parameters, a current peak with a chargeand a specific energy typically simulated with the 10/350us waveform to represent partial lightning
currents. This waveform is used with peak Imp current value stated. for the mains Type 1 SPD Class I test and typically for data telecom SPD TestCategory D.

SPDS) as well as data telecom Test Categories C and B Modes' refer to tie combinations of conductors in which
transient overvoltage car Lightning transients are generally disturbance with respect to Eat commonmode), whist
switching transients are disturbances between line/phase and neutral (differential mode). During propagation mode
conversion can occur (e.g. as a resultof flashover). Hence transients can exist simultaneously between any combinations
of conductors. Electronic systems now pervade almost every aspect of our lives, from the work environment, through
filling the car and even shopping at the local supermarket. As a society, we are now heavily reliant on the continuous
and efficientrunning of such systems. The use of computers, electronic process controls and telecommunications has
'increased exponentially’ during the last two decades. Not only are there more systems in existence the physical size of
the electronics involved has reduced considerably. This reduction in size means less energy is required to damage
components.
The operation of electronic systems can be severely affected by lightning activityduring thunderstorms or
electrical switching events. Both can cause very short duration increases in voltage on mains power
and/or data
Communication/signal/telephone lines, with potentially devastatingconsequences. These increases in voltages are
called surges or transient over voltages, all sorts of electronic equipment are at risk such as
•Computers
•Building management systems
•PABX telephone exchanges • CCTV equipment
•Fire and burglar alarms
•Uninterruptible power supplies • programmable logic controllers (PLCS)
•Plant sensors, telemetry and data acquisition equipment
•Weighbridge installations
A lightning surge is severe enough to present a risk of loss of life through fire and/or electric shock hazards through a
dangerous flashover. This can occur when the surge voltage exceeds the withstand rating of the cable insulation or
equipment. The home environment has also evolved everyday activities rely on electronic equipment Products such as
plasma televisions home theatre equipment alarms. microwaves and washing machines are all vulnerable to voltage
surges Protecting all home electronic equipment is simple with the qualified installation of a surge protection device
Products such as LCD screens. computer networks. data servers and industrial equipment including PLCs
provide essential services now crucial to business operational productivity Protection against the effects of
