![]() Protection includes overcurrent, ground fault, neutral voltage displacement, sensitive or restricted ground fault, voltage dependent overcurrent or underimpedance, under and overvoltage, under and overfrequency, reverse, low forward or overpower, field failure, negative phase sequence thermal, negative phase sequence overcurrent and overvoltage, turbine abnormal frequency, generator thermal and overfluxing, rotor ground fault, rate of change of frequency, check synchronizing, transformer thermal and loss of life as well as VT and CT supervision.The MiCOM P343 is suitable for protection of larger or more important generators, providing 100% stator ground fault via a 3rd harmonic measuring technique, pole slipping and unintentional energisation at standstill protection.The P344 is similar to the P343 but includes a second neutral voltage input for ground fault / interturn protection.The P345 is similar to the P344 but includes 100% stator ground fault protection via a low frequency injection technique. ![]() The MiCOM P342 is suitable for protection of generators which require cost effective high quality protection. ![]()
