description

The parameters for instantaneous phase overcurrent protection 3-phase output PHPIOC (50) are set via the local HMI or PCM600. This protection function must operate only in a selective way. so check all system and transient conditions that could cause its unwanted operation. only detailed network studies can determine the operating conditions under which the highest possible fault current is expected on the line. in most cases, this current appears during three-phase fault conditions. but also examine single-phase-to-ground and twophase-to-ground conditions. also study transients that could cause a high increase of the line current for short times. a typical example is a transmission line with a power transformer at the remote end, which can cause high inrush current when connected to the network and can thus also cause the operation of the built-in, instantaneous, overcurrent protection. GlobalBaseSel: selects the global base value group used by the function to define (IBase), (VBase) and (SBase). OpModeSel: This parameter can be set to 2 out of 3 or 1 out of 3. The setting controls the minimum number of phase currents that must be larger than the set operate current pickup for operation. normally this parameter is set to 1 out of 3and will thus detect all fault types. If the protection is to be used mainly for multi phase faults, 2 out of 3 should be chosen.
