- 2. Effects of Electrical Failures • Loss of revenue due to downtime • Cost of labour for trouble shooting, repairing, restarting etc • Cost of damaged equipment and material including repairs, replacements, scrapped material • Cost incurred due to injuries suffered by personnel www.idc-online.com/slideshare Technology TTrraaiinniinngg tthhaatt WWoorrkkss
- 3. Reasons for Genesis of Problems • Design deficiencies • Quality of installed equipment • Installation deficiencies • Operation deficiencies • Quality of maintenance carried out on the equipment • Inherent ageing and deterioration of equipment • External causes like hostile environment, malfunction of protection devices etc. www.idc-online.com/slideshare Technology TTrraaiinniinngg tthhaatt WWoorrkkss
- 4. Problem categories - Electrical Electrical problems can arise either in the electrical circuit or in the equipment and components connected in the electrical circuit and can be categorized as • Open circuits and short circuits • Active and passive faults • Incipient and solid faults www.idc-online.com/slideshare Technology TTrraaiinniinngg tthhaatt WWoorrkkss
- 5. Problem categories - Mechanical • Mechanical problems - are on account of mechanical causes like bearing defects, breakages, jamming of moving parts, lubrication problems etc. • Mechanical problems can lead to electrical problems. A defective motor bearing can cause the rotor to foul with the stator of the motor causing an electrical flashover. www.idc-online.com/slideshare Technology TTrraaiinniinngg tthhaatt WWoorrkkss
