Detailed Intelligent Reactive Compensation Controller (JKFC1 - c) Description
Main features:
a) Utilizes "watchdog" circuit hardware with dual anti - jamming
measurements for normal operation
b) Controls physical quantity of power factor, reactive power double
parameters to higher accuracy of control and compensation
c) Output adopts total split phase compensation method to compensate
each phase freely and respectively
d) Strong protection function shields output quickly when there is
something wrong in the circuit
e) Standard: DL / T 597 - 1996 and JB / T 9663 - 1999
Main functions:
a) Digital tube can show real power factor (default three phases shown
in ), real voltage, real frequency and real current by inquiry
key
b) Input point, over - voltage protection values, time delay, current transformer
ratio, split phase compensation capacitance and hand
held / automatic mode can be set and modified through adjustable key
c) When overcompensation exceeds the cutoff point, part or all of
capacitance will be cut automatically
d) When system voltage exceeds the set over - voltage, the over - voltage
indicator light will shine and the capacitance will be cut slowly
() step by step
e) When system reactive power quantity is less than one group of
capacitance, the output will be cut off to avoid input shock
f) When current transformer has two incomplete circuits or it is less
than the accuracy of the controller, low - current indicator light
will shine, fault indicator light will flash and the capacitance
will be cut step by step
