High Voltage (HV) thyristor-switched Automatic Power Factor Correction (APFC) systems are used to manage and correct the power factor in electrical systems with Voltages up to 11 kV. It helps working at HV effectively in minimizing penalty due to low PF condition and also reduction in kVH consumption.
Most of the steel industries consume very high power at high Voltages. Consumers normally divide capacitors between HV & LV Voltage levels. This is a good practice, but it is un-economical & cumbersome. We have thyristor switching systems for capacitors up to 11kV. This system enables HV capacitors to be switched “ON” & Switched “OFF” every 5 seconds and unlimited operation. Thus the system works as an APFC at 11 kV. We are in process of developing such systems suitable for 33 kV applications. We expect it to be perfected for use in industries shortly.
This system is also used as a Solid state breaker for switching capacitors up to 11 kV. There is no limitation on number of “switchings” in any time duration. The operation can be automated or connected with the load, using proper interface.
We are a Mumbai (India) based licensed electrical contracting company, Presently engaged in the main business of design, manufacturing & supply of various equipments for the management of electrical reactive energy in industries and modern day commercial complexes.
