Overview

The ABB 216GW62 (HESG324008) is a precision input transformer unit designed for ABB’s REG 216 numerical generator protection systems. Its primary function is to scale and electrically isolate analog signals from current transformers (CTs) and potential transformers (PTs), providing safe and accurate signal conditioning for downstream protection and control modules.

The unit supports multiple CT and PT configurations, including differential protection setups for generator terminals. With a DIN IP30 protection class, it ensures robust defense against dust and incidental contact.

For example, in a hydroelectric power plant, the 216GW62 can interface with six CTs to monitor generator terminal currents, enabling differential protection logic and improving system safety.

Technical Data

Typical Applications

• Generator Differential Protection: Interfaces with CTs to measure terminal currents and detect imbalances.

• Voltage Monitoring and Isolation: Conditions PT signals for safe input to protection relays.

• Power Plant Automation: Supports signal acquisition for turbine and generator control systems.

• Substation Protection Systems: Provides isolation and scaling for high-voltage CT/PT signals.

• Retrofit Projects: Replaces legacy transformer units with modern, DIN-compliant modules.

The 216GW62 is also used in custom protection schemes where multiple CTs and PTs are integrated into a single transformer interface.
