for 500 kV and higher networks.
U.SEC Nominal secondary voltage 10-690 V 120 V The nominal secondary line-to-neutral (in 4LN3,
3LN3 and 3BLN3 wiring modes) or line-to-line (in
4LL3, 3LL3, 3BLL3, 3OP2, 3OP3 and 3DIR


Always specify the wiring mode and transformer ratings prior to setting up setpoints and analog outputs.

The maximum value for the product of the phase CT primary current and PT ratio is 57,500,000. If the
product is greater, power readings are zeroed.
