6.4.4 Capacitor bank
6.4.4.1 Menu
ACTUAL VALUES  METERING  CAPACITOR BANK
The capacitor bank menu contains the actual values for the voltage differential, neutral voltage unbalance, phase current
unbalance, and neutral current unbalance elements.
6.4.4.2 Voltage differential
ACTUAL VALUES  METERING  CAPACITOR BANK  VOLTAGE DIFFERENTIAL  VOLTAGE DIFFERENTIAL 1(3)
These actual values display the bus and differential signals in per-unit values of the nominal bus voltage for phases A, B,
and C.
6.4.4.3 Neutral voltage unbalance
ACTUAL VALUES  METERING  CAPACITOR BANK  NEUTRAL VOLTAGE...  NEUTRAL VOLTAGE UNBALANCE 1(3)
This menu displays the magnitudes (in pu) and angles of the neutral point and bus V0 voltages for the neutral voltage
unbalance elements. The magnitudes of the compensating operating voltage and restraining voltage (in pu) also display.
6.4.4.4 Phase current unbalance
ACTUAL VALUES  METERING  CAPACITOR BANK  PHASE CURRENT...  PHASE CURRENT UNBALANCE 1(3)
