FTT7111 – Overfluxing Relay
Products family : Sector : Industry The FTT 7111 is dedicated to the protection of power transformers against overfluxing. Saturation of the magnetic circuit would increase the losses. The associated heating involves premature ageing of the insulation, which can lead to internal faults and breakdown. The flux in the magnetic circuit is proportional to the…
TARTN20D – Transformer Voltage Regulator AVR
Products family : Transformer Protection Sector : Transmission, Industry The TARTN20D is intended for automation transformers HV / MV and HV / MV. It allows the regulation of the MV voltage to a predetermined set point, the tap changer in the decision-shift control.
DTT7031 – Transformer Differential Protection
Products family : Transformer Protection Sector : Industry The DTT 7031 is a biased threephase differential relay designed to protect high voltage transformers against internal faults. Its very rapid operation limits the damage due to short-circuits between phases, between turns on the same phase, or between windings and eart/ground if the earth/ground fault currents can…
NPDT620 / NPDT630 – Transformer Differential Protection
Products family : Transformer Protection Sector : Industry, Railway The differential protection relays NPDT 620 and NPDT 630 are designed to provide fast and selective protection of 2 and 3-winding three-phase transformers. The relays can detect various types of fault such as phase-phase faults, inter-winding faults and earth-fault. Restricted earth-fault protection, on primary and secondary…
