IGCT vs IGBT: IGCT power loss low in on-state

Two of the most crucial tests that every Current Transformer (CT) & Potential Transformer (PT) undergoes are: High Voltage (HV) withstand test and the Partial Discharge (PD) test. The HV test challenges insulation to prove its strength under extreme stress voltage. The PD test uncovers even the smallest discharge activity that could lead to future failures. At Aarsea Industries, we have an in-house testing facility to carry out both HV withstand test upto 100kV and PD test under a controlled, soundproof and dustproof environment for the highest accuracy as per  Indian Standard 16227:2016 Contact for more #Currenttransformer #HTCT #LTCT #TapeWound #Voltagetransformer #EpoxyResin #ElectricalPanel #HighVoltage #HV #PartialDischarge #PD #IS16227

🚀 Episode 4 of the Variable Frequency Drive Knowledge Channel is now live! The Core of MV VFD Inversion Circuits: How IGBTs & PWM Create Perfect Waveform in VFDs？ 🎯 Through precise PWM control, the IGBTs output a series of carefully timed DC pulses. By modulating the width of these pulses, the average voltage over time perfectly mimics a smooth sinusoidal waveform. This synergy allows for precise control of a motor’s speed (frequency) and torque (voltage). 🔍 Got thoughts or questions? We’d love to hear from you! 💬 What topics should we cover next?

EV fast chargers demand relentless power, but heat is the silent killer. How are we tackling extreme thermal challenges in IGBT modules to shrink footprints and boost reliability? Liquid cold plates are essential for managing the significant heat generated by IGBTs, enabling higher power densities and compact designs (Advanced Thermal Solutions). Minimising thermal resistance is key, especially at the module-to-cold plate interface (Semikron Danfoss). Surface flatness and roughness directly impact thermal contact resistance and TIM thickness uniformity (NDIA GVSETS). Poor interfaces create bottlenecks. Revolutionary direct liquid cooling designs, integrating channels directly into the DBC substrate, eliminate multiple thermal interfaces, significantly shortening the heat path (NDIA GVSETS). This allows up to a 10x reduction in volume per watt dissipated for SiC IGBT modules, vital for EV fast charger reliability and footprint (NDIA GVSETS). Concrete takeaway: Optimal liquid cooling demands meticulous interface management, or better yet, eliminating interfaces for superior heat transfer.

⚡️ How Transformers Keep Our Power Stable: Tap-Changing, AVR, and LTC Explained In electrical power systems, keeping voltage stable is no small task—especially when demand keeps fluctuating! That’s where transformers with On-Load Tap Changers (OLTC) and Automatic Voltage Regulators (AVR) come in. 🌟 These smart mechanisms help adjust the voltage automatically by changing transformer winding taps, all while the transformer is live and supplying power. No need to shut down or stop the flow. Here’s a simple way to understand the key voltage levels involved in the design: 🔧 Design Level – 110% → Gives extra boost when needed, helping handle peak demand or compensate for losses. ⚡ Normal Operation – 100% → The sweet spot where everything runs smoothly under regular conditions. ⚠️ Shutdown Threshold – 80% → If voltage drops too low, the system will alert or shut down to prevent damage. By intelligently managing these levels, OLTC and AVR help ensure reliable power supply and protect the grid from instability. Powering our world, one smart adjustment at a time. 🌍💡 #powersystems #electricalengineering #transformers #AVR #gridstability #cleanenergy #engineeringsimplified

🔄 Is your secondary voltage always stable — even when your grid isn’t? Let’s talk about the real-time hero inside your transformer… ⚡ On-Load Tap Changers (OLTCs) They adjust the transformer’s turns ratio under load to keep output voltage steady — and yes, they do it live and smoothly. 👀 But how does it really work? With calculations? At different input voltages? Let’s break it down visually👇 🎯 GIF Breakdown: OLTC Action in Real-Time ✅ Why OLTC? Grid voltages fluctuate. Loads vary. But your supply must stay steady. OLTC ensures just that — without shutdown. ✅ What happens when voltage drops? 🔹 Input = 31.5kV instead of 33kV 🔹 Output drops to ~10.5kV 🔹 OLTC taps down by -4 steps (1.25% each) 🔹 Output = ~11.02kV restored 🔧 Live voltage correction in action ✅ What about overvoltage? 🔹 Input = 34.6kV 🔹 Output rises to ~11.55kV 🔹 OLTC taps up by +4 🔹 Output brought back to ~11.01kV 🧯 No surge. No stress on equipment. 🎓 Engineers, if you work with transformers, grid-connected systems or voltage control — this is a fundamental you must master. 💬 What’s your experience with OLTC maintenance, failures, or control strategies? ♻️ Repost to share with your network if you find this helpful. 🔗 Follow Ashish Shorma Dipta for posts like this. #PowerSystem #TransformerProtection #OLTC #VoltageRegulation #ElectricalEngineering #TapChanger
