Rơ le bảo vệ quá dòng IPR-A155.

Current Protection Relay IPR-A is designed to protect medium voltage lines against over-current and short circuit scenarios present in line fault or ground fault even under disturbances.

Currents are measured throughout current transformers (CT) from each line. The information is internally processed in order to take the current protection actions defined under ANSI, IAC or IEC standard.

• CT primary ratio selectable in 5 A steps (10 A to 6000 A)
• Line and ground RMS currents measurement
• 1 trip relay and 2 programmable auxiliary relay
• Control power drop or internal fault relay
• Digital inputs: 1 breaker status - 3 programmable
• Touchpad programming
• Breaker operation and trip failure
