Transformer voltage controller type RNTr-1
Application
- All controlling systems equipped with sub-load tap switches on the high- and medium voltage lines co-operating with the earthed, compensated or isolated star point
- Voltage control of the energy transformers
- Voltage stabilisation at the power trnsmission lines ends
Advantages
- Instant and reliable reaction for the voltage and current fluctuations
- High regulation quality
- Multi-processor measuring and decision system
- Digitalised data processing
- Input and output galvanised separation
- Operation on two- or three-phase transformers
- XR and Z compensation set independently for the individual measuring circuits
- Manual and automatic mode of operation
- Tap switch engine overcurrent protection
- Remote control of the tap switch
- Operation course registration
- LINUX operating system
