Summary
Low voltage power capacitor compensates inductance load. Due to load changes, capacitors in automatic reactive power compensation systems are sometimes put into operation nearly 100 times a day, so quality and durability have a decisive impact on performance. Capacitors in the compensation system may be exposed to currents exceeding the rated value in operation. ENTES ENT.C series capacitors are designed to withstand heavy loads and adverse conditions that shorten their service life during compensation. High-level standard processes and long-term testing provide durability assurance.
ENTESENT.C series capacitors adopt the latest safety technology. With the help of over-voltage circuit breaker system, it can prevent capacitor explosion when its service life expires or thermal stress occurs.
The ENT.C series capacitors adopt metallized polypropylene film and have self-healing characteristics.
With improved solid housing, compact size, excellent heat conduction performance, easy parallel connection and over-voltage circuit breaker system, ENT.C series capacitors are ideal solutions for new or upcoming reactive power compensation systems.
Capacitors are one of the most important components of compensation system. Their reliability is determined by time and various conditions. The capacitance value of capacitor decreases with time, which leads to inadequate reactive power compensation or failure. The service life of ENT.C series capacitors is up to 130,000 hours, which guarantees their reliability under long time and various test conditions.
The inrush effect will occur when the compensating capacitor is put into operation. These effects are caused by the high instantaneous current at the input. The input current of the capacitor leads to a serious shortening of the service life of the capacitor itself and other capacitors connected to the circuit. The correct way to solve such adverse effects is to use special load contactors with capacitors.
