2. GENERAL
Power Factor Controllers are used for measurement and control of power
factor control units for central reactive power compensation. The Power Factor
measured by RG-T is compared with the set point values and in order to provide
necessary compensation, Power Factor Controller switches capacitor banks
ON and OFF automatically. RG-T is a microcontroller relay, designed for above
application in 144x144 case for ush mounting with rear plug-in connectors.
In addition to displaying the system’s Cos in Automatic Operating Mode, RG-T j
displays the RMS values of Voltage(V) and Current (I), Active Power (W), Reactive
Power (VAr) and Apparent Power (VA) of measuring phase.

5. CONTROLS AND MENU OPERATIONS
All settings are made by Menu. The set values except operating mode are kept in memory
even if the device is switched o.When it is switched on, it starts compensation with
the values stored in the memory in Automatic Operating Mode. After entering Menu by
