Get a fault on the SEPAM 40 series TC fault or TP phase fault but don't know what it means.
SEPAM 4x Series
"TC faults" and "TP phase faults" relate to Current Transformer Supervision (CTS) and Voltage Transformer Supervision (VTS), which can be set using the advanced UMI or SFT2841 software.
When enabled, the SEPAM relay will supervise the current and voltage APS_SENSORS and make sure that a phase isn't missing or a fuse isn't blown. The status of the CTS or VTS can be viewed via Modbus using TS indicators.
TC fault = CTS fault
TP Phase fault = VTS fault relating to phase difference between current and voltage
TP Vo fault = VTS fault relating to 3 phase voltage sum (Vr)
