Input Transformer ABB 216GW62 HESG324008 for High-Voltage Signal Isolation

Description

TheABB 216GW62 (HESG324008)is aprecision input transformer unitdesigned for ABB’sREG 216 numerical generator protection systems. Its primary function is toscale and electrically isolate analog signalsfromcurrent transformers (CTs)andpotential transformers (PTs), providing safe and accurate signal conditioning for downstream protection and control modules. The unit supports multiple CT and PT configurations, includingdifferential protection setupsfor generator terminals. With aDIN IP30 protection class, it ensures robust defense against dust and incidental contact. For example, in ahydroelectric power plant, the 216GW62 can interface with six CTs to monitor generator terminal currents, enablingdifferential protection logicand improving system safety.
