Its primary role is to serve as the physical and electrical buffer between high-energy field instrumentation—such as Current Transformers (CTs) and Potential Transformers (PTs)—and the sensitive electronic processing modules of the protection rack.

In a hydroelectric or thermal power plant setting, the module interfaces with CTs located at both the neutral and terminal ends of the generator windings. By providing perfectly matched isolation and scaling, it allows the REG 216 system to detect minute current imbalances that indicate internal faults. Its IP30-rated enclosure provides a necessary layer of physical security against dust and accidental contact in busy control cabinets, while its transformer-based isolation protects the wider DCS network from ground loop currents and surges originating in the switchyard.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":44096021037155,"sku":"216GW62 HESG324008","price":180.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/2775\/3315\/files\/222_038a4f5a-3e55-4a29-b192-df01f232fe47.png?v=1775023148","url":"https:\/\/precisemodule.com\/products\/input-transformer-abb-216gw62-hesg324008","provider":"Precise Module Ltd.","version":"1.0","type":"link"}
