Main Features and Advantages
Advanced Dielectric Technology
Your investment is protected by our all-film polypropylene dielectric system. This biodegradable synthetic fluid impregnation ensures long service life and environmental safety.
Internal Element Fusing
Individual element protection prevents total bank shutdown. When one element fails, your system continues operating with minimal capacity loss.
Intelligent Control Systems
Automatic Power Factor Controllers monitor your system continuously. They provide precise switching based on reactive power demand and voltage conditions.
Harmonic Management
Detuning reactors prevent resonance issues. Your system stays protected from harmonic amplification and voltage distortion.
Weather-Resistant Design
Galvanized steel enclosures withstand harsh environments. Salt mist corrosion and extreme temperatures won't compromise performance.
Practical Applications
Industrial Manufacturing Plants
Heavy machinery creates significant reactive power demand. Our banks maintain power factor above 0.95, eliminating utility penalties while improving motor performance.
Mining Operations
Ball mills and crushers cause rapid load fluctuations. Fast-switching vacuum contactors provide instant compensation during equipment startups and variable loading.
Renewable Energy Facilities
Wind and solar installations require Grid Code compliance. Reactive power injection during peak generation ensures continuous grid connection without voltage violations.
Utility Distribution Networks
Transmission line loading decreases with strategic VAR support. End-of-feeder voltage regulation improves while reducing I²R losses throughout the system.
How It Works
Your medium voltage capacitor bank operates through automatic reactive power sensing. Power factor controllers continuously monitor system conditions through current and voltage transformers.
When inductive loads increase reactive power demand, contactors energize capacitor steps. This injection of leading VARs corrects lagging power factor immediately.
Harmonic filters prevent resonance between capacitors and system inductance. Detuning reactors shift resonant frequencies below problematic harmonic orders.
Protection relays monitor unbalance conditions and over-currents. Automatic disconnection occurs before equipment damage, ensuring personnel safety and system integrity.
