Wider range of РПН tap-position indicators

The range of on-load tap-changer position indicators (ratiometers) has been extended with models that work with selsyn sensors. When ordering, specify the sensor type, the number of tap positions and whether an RS485 interface is required. Sensor types available: ИЦ407 — resistive sensor, ИЦ407С — selsyn sensor, 4–20 mA current loop, BCD code. An additional remote indicator is available, allowing the display to be sited up to 1200 metres away. РПН tap-changer position indicators are used at 35, 110, 220 and 500 kV substations and at generating plants, with drives of Bulgarian and German manufacture. The indicator shows the tap-changer position. It replaces instruments such as УП2, УП22, УП23, УП24, УП25.
