How many volts is the relay protection current

Even the most modern digital protective relays operate on the traditional 125 VDC supply voltage rather than 120 VAC as is common with other types of industrial controls. CT's transform line current down to a signal level that is acceptable to the relay. Multiple relays can use the same CT. It prevents safety hazards and damage to equipment. Many industries use voltage protection relay systems, especially those in high-voltage. In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. It uses inputs such as nominal coil voltage, coil resistance, load voltage, load current, and power factor to. Current transformers step down the monitored current to a secondary (output) range of 0 to 5 amps AC to power the protective relay.
