MEGGER INGVAR PRIMARY Current Injection Test System

The Megger INGVAR Primary Current Injection Test System is an exceptionally robust and reliable solution engineered for primary injection testing of protective relay equipment and circuit breakers. This test system also finds utility in measuring the turn ratio of current transformers among other applications that demand high variable currents.

The INGVAR system is uniquely composed of two main components: a control unit and a current unit. Both parts are designed for portability, making the system ideal for field use where mobility and ease of setup are crucial. This design allows for quick assembly and connection, enabling efficient and timely operations during testing sessions.

One of the system’s significant advantages is its capability to generate high currents needed for primary testing. This feature is essential for ensuring that circuit breakers and relays function correctly under actual operating conditions, thus safeguarding electrical systems from faults and ensuring operational reliability.

The user-friendly interface of the INGVAR system further simplifies its operation, allowing technicians to perform complex tests with minimal training. The system’s robustness and precision make it a vital tool for the maintenance and testing of high-capacity electrical systems, particularly in industrial and utility settings where accuracy and dependability are paramount.
