Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of
To allow communication, relays are provided with a front Micro USB Port and with an optional remote communication RS485 port (Modbus RTU) and ethernet RJ45 port (Modbus TCP protocol) on the
The concept "Self-Power" defines the supplying mode of electronic protection relays for Medium Voltage. It means that there is no need for auxiliary voltage to power the relay and that the energy is obtained
OC&EF Dual & Self Powered Protection Relay The SIA-C is an OC&EF protection relay with self-powered and dual-powered (self-powering + auxiliary power) options.

Protection Relays by Application From overcurrent protection or motor to complex distance protection, our protection relay give you the safety and reliability needed
When testing self-powered relays, many technicians ask why a current of 1 A injected by the relay test set is not registered as 1 A by the relay.
They are a type of protective relay that operates using power extracted from the system being monitored, eliminating the need for an external power source. This key characteristic makes
This way, relay will only withstand rated injected current during adjusted time at protection function settings, not maintaining current injection constantly, which could become a damaging situation for
