Transformer terminal RET 541
The RET 541 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 541 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.
These 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.
- Supports a large number of protocols
- Part of the RE500 technology series
- The smallest of the RET 541/543/545 family, 15 inputs
