Features of Siemens Siprotec 5 7SJ82 Overcurrent & Feeder Protection Relay
Introduction
The Siprotec 5 7SJ82 relay Protection hand-off is a multi-utilitarian engine assurance transfer. It is intended for the security of offbeat engines, everything being equal. The transfers have every one of the necessary capacities to be applied as a reinforcement hand-off to a transformer differential hand-off. The Siemens Siprotec 5 7SJ82 Overcurrent & Feeder Protection Relay elements have adaptable security capacities. Up to 20 extra assurance capacities can be made by the client. Subsequently, insurance of progress for recurrence or opposite power assurance can be acknowledged, for instance. The hand-off gives electrical switch control, further exchanging gadgets, and robotization capacities. The coordinated programmable rationale (CFC) permits the client to add their own capacities, for example for the robotization of switchgear (interlocking). The client is likewise permitted to create client characterized messages.
