Description
Raytech Multiplexer MUX R is designed to drastically reduce cabling time and increase test performance. It is made to be used with Raytech Winding Resistance and Turns Ratio Meters. Any MUX R configuration can be easily controlled by a Winding Resistance Meter touch panel or by remote.
Features
- Minimizes cabling time
- Does all measurements with one cabling per transformer, including Winding Resistance and Turns Ratio
- Using a 4-wire measurement ensures the same high precision as measuring without a Multiplexer.
- Use up to three Multiplexers and measure transformers with three winding systems with one cabling sequence
- Get your own configuration containing from one to three Multiplexers, from one to three Winding Resistance Meters and one Turns Ratio Meter
- Control your Tap Changer with a powerful tap changer interface
- Operate all instruments on a touch screen or by remote control
- Get a customized complete solution containing WR, TR and Multiplexers. Ask Raytech for a ATOS (Automatic Transformer Observing System)
