ABB RET615 Transformer Prot And Control Relay

Description

The RET615 Transformer Protection and Control Device offers eight standard configurations to provide corresponding grounding fault protection schemes suitable for different neutral point grounding methods, such as high-resistance grounding or low-resistance grounding, in transformer applications. It digitally compensates for CT ratio errors and phase shifts for all vector groups used in power transformers. The RET615 also features local or remote control adaptation for high-side circuit breakers of transformers.

Key Advantages
