Because energy parameters are accumulated, these values should be recorded and then reset immediately prior to chang-
ing VT characteristics.
Two
banks of phase/auxiliary VTs can be set, where voltage banks are denoted in the following format (
X
represents the
module slot position letter):
Xa
, where
X
= {

See the
Introduction to AC Sources
section at the beginning of this chapter for details.
With VTs installed, the relay can perform voltage measurements as well as power calculations. Enter the
PHASE VT F5 CON-
NECTION
made to the system as “Wye” or “Delta”. An open-delta source VT connection would be entered as “Delta”.
The nominal
PHASE VT F5 SECONDARY
voltage setting is the voltage across the relay input terminals when nominal
voltage is applied to the VT primary.
For example, on a system with a 13.8 kV nominal primary voltage and with a 14400:120 volt VT in a delta connec-
tion, the secondary voltage would be 115; that is, (13800 / 14400) × 120. For a wye connection, the voltage value
entered must be the phase to neutral voltage which would be 115
/
= 66.4.
On a 14.4 kV system with a delta connection and a VT primary to secondary turns ratio of 14400:120, the voltage
value entered would be 120; that is, 14400 / 120.
