Wiring Diagrams

Since the relay takes one voltage input, power and VAR metering is not accurate for unbalanced
conditions. In addition, depending on which winding the VT is on, the power flows and vars displayed
may be opposite in direction to the actual system flow; e.g. in the case of a generator step-up
NOTE
transformer, depending on the relay winding assignments and which side of the transformer the VT
is connected to, the power may be negative when the generator is producing positive MW. This can
be corrected by reversing the voltage input into C11 and C12.
