Product Description

ABB TRANSFORMER TERMINAL RET 543 NUMERICAL RELAY

THE RET 543 TRANSFORMER TERMINAL IS DESIGNED FOR THE PROTECTION, CONTROL, MEASUREMENT AND SUPERVISION OF TWO-WINDING POWER TRANSFORMERS AND POWER GENERATOR-TRANSFORMER BLOCKS IN DISTRIBUTION NETWORKS

The RET 543 terminals are loaded with functionality to suit your application. Besides the three-phase stabilized current differential function featuring 2nd and 5th harmonic restraint, the basic version terminals incorporate three-phase over-current, non-directional earth-fault, restricted earth-fault, transformer thermal overload and phase unbalance protection.

The multi-version terminals further include over-voltage and under-voltage supervision, directional earth-fault, residual voltage and over-excitation protection, over-frequency and under-frequency protection, and under-impedance protection. Enhanced with an optional automatic voltage regulator function the terminal forms an integrated transformer management unit.

A special control version terminal, which includes just voltage regulator and control functions is also available.
