Frequently Asked Questions

Transformer input configuration, protection options, communications and retrofit guidance for 745-W3-P511-G51-HI-R-E.

Which transformer arrangement does W3 serve?

W3 specifies three windings per phase. Match the protected transformer and CT wiring to the three-winding configuration before setting differential protection.

How are phase CT ratings allocated by P511?

P511 selects 5 A phase current input for winding 1 and 1 A inputs for windings 2 and 3. Confirm all three installed CT secondary ratings before ordering or commissioning.

Which ground CT inputs are selected by G51?

G51 provides a 5 A ground input for windings 1 and 2 and a 1 A ground input for windings 2 and 3. Check the actual ground-CT wiring against this ordering code.

Which auxiliary supply range matches the HI suffix?

HI is the high-voltage supply option: 90–300 V DC or 70–265 V AC at 48–62 Hz. Verify station supply before energizing the relay.

Which protection and display options are included?

R denotes the restricted-ground-fault option. E denotes the enhanced display with larger LCD and improved keypad.

Does this E variant include Ethernet communications?

No Ethernet port is implied by E. The brochure assigns 10BaseT Ethernet to the T option; the relay family provides front RS232 and rear RS485 serial interfaces.

How should a 745-to-845 migration be scoped?

GE Vernova lists the 745 as legacy and identifies the 845 as a successor path. Review CT ratings, protection settings, wiring, communications and panel fit; do not treat 845 as an automatic drop-in replacement.
