Automatic Power Factor Controller Series - RM,NAAC 3P (3 Phase) & Economy Series RC 7

 


 

RM Series P.F. Controllers are used for measurement and control of P.F. control units for central reactive power compensation. The P.F. measured by Neptune RM is compared with the set values and in order to provide necessary compensation. P.F. Controller switches capacitor banks ON & OFF automatically. RM is Single Phase CT Sensing micro controller relay, designed for above application in 144x144 case for flush mounting with rear plug-in connectors. In addition, Neptune RM displays the following values.

  1. Power Factor

  2. Cosφ

  3. Ph-Ph volt. (VAC)

  4. Current (I)

  5. Active power (W)

  6. Total active power (IW)

  7. Reactive power (Var)

  8. Apparent power (VA)


Microcontroller based programmable RM series relays are manufactured with 8 & 12 capacitor steps. It can work either in automatic or manual mode.

NAAC-3P Series are ultimate solution for compensation of unbalanced loads. Further to RM series standard features, NAAC-3P series controllers function as if a reactive energy meter. The Compensation is realized by measuring the reactive power of system, through 

3 current transformers from 3 phases. This makes NAAC-3P Series a unique solution for unbalanced load compensation.
