1.1  About user manual

This User Manual is designed to help you for quick understand the installation, debugging, working parameter and menu operation of series RPCF reactive power auto compensation controllers. Before installation and operation please read this section very carefully.

1.2  Usage Scope

RPCF series reactive power auto compensation controllers is suitable for automatically adjusting of low voltage distribution system capacitor compensating device to make power factor get user’s predetermined state, increase the utilization efficiency of power transformer, reduce line loss, and improve the voltage quality of power supply.

 

2.1  Accounting switch on and switch off capacitance by the fundamental wave reactive power may avoid any form switch on and switch off vibration, and be able to demonstrate the electrical network power factor correctly under the harmonic wave situation.

2.2  High measuring accuracy of power factor, wide display scope.
