Relé de proteção à terra da falha de terra, relé protetor de 5A Digitas
Ground Earth Fault Protection Relay , 5A Digital Protective Relay A relay used in the power system to detect neutral or ground faults measure the vector difference of the three phase power, or measure the neutral current directly. Description: Purple Horn Relay is a micro-mrocessor based electronic protection device designed to recognize current leakage to ensure the protection of electrical installations and persons against direct and indirect contacts. cost-effective earth fault
Proteção protetora da sobrecarga dos relés IDMT do tempo inverso automático
Automatic Inverse Time Protective Relays IDMT Overcurrent Protection Time overcurrent relays operate with a time delay, which is adjustable. For given setting, the actual time delay depends on the current through the relay coil. Higher current will cause a faster operation of the relay. The minimum relay operation current (pick-up current) is also adjustable. The most commonly used overcurrent relay has both the instantaneous response for very large currents and the inverse
