Accurate Low Voltage Protection Devices , Reactive Power Automatic Phase Compensation Controller
General Description
RPCF3 series automatic phase discriminated reactive power compensating controller has all the advantages of RPCF series, meanwhile this controller sample the signals of voltage, and current from three phases respectively, it will avoid the var meter recording quickly or inversely rotating even if the power factor has been compensated fully in three phase unbalanced system.
Function features
1. On basis of 3 phases fundamental wave reactive power, calculate the reactive power to be switched on, it can avoid switching shock of any forms, it can accurately display the power factor of system
with harmonic wave.
2. High measurement accuracy, wide display scope
3. Real time display general power factor and fundamental wave PF
4. Real time respectively display 3 phases voltage, current, active power, reactive power, apparent power
5. Total 12 kinds of coding output can be chosen
6. 6 kinds of schedules can be chosen by user (distribution the circuit nos of corporate compensation, or respective compensation)
7. 16 circuits of output at maximum
8. Human friendly interface, convenient operation
9. Various control setting can be adjusted digitally, directly and easily.
10. Automatic and manual operations, two modes provided..
11. Over voltage and absent voltage protection provided.
12. Data not lost even if power shut down.
13. Current signal input resistance ≤0.01Ω
14. Compensating power factor able to be adjusted:0.70 lag~0.7 forward.
