  • 简介:traditional current differential protection cannot identify such fault for the sake of sensitivity limited by normal load current. RCS-985 Series generator-transformer unit protection is equipped with transformer DPFC percentage restraint differential protection and generator DPFC percentage restraint differential protection. Comparing with traditional percentage restraint differential protection,DPFC percentage restraint differential protection makes use of DPFC in phase current on each side of transformer and DPFC in differential current,Inter-turn fault is the main kind of fault in electric power transformer. It is meaningful that employing sensitive and secure protection to identify inter-turn fault inside power transformer. In RCS-978 series power transformer protection

  • 简介:thus the sensitivity is high for internal low percentage inter-turn fault without risks of unwanted operation under external fault.,Integration of main and backup protection with duplicate allocation reduces the total number of power transformer protection devices,Lifting differential setting or introducing differential protection with product- quantity restraint will lose sensitivity or even lead to missing operation. With identifying harmonic component and waveform character of differential current asynchronous anti-TA saturation criterion can distinguish between internal fault and TA saturation under external fault.
