2 PRODUCT DESCRIPTION
FAULT LOCATOR
Number of independent fault locators: 1 per CT bank (to a maxi-
mum of 5)
Method:
single-ended
Voltage source:
wye-connected VTs, delta-connected
VTs and neutral voltage, delta-connected
VTs and zero-sequence current (approxi-
mation)
Maximum accuracy if:
fault resistance is zero or fault currents
from all line terminals are in phase
Relay accuracy:
±1.5% (V > 10 V, I > 0.1 pu)

for frequency measurement)
I = 0.1 to 0.25 pu:
±0.005 Hz
I > 0.25 pu:
±0.001 Hz (when current signal is used
for frequency measurement)
DEMAND
Measurements:
