High Current Generator – AC & DC Primary Injection Test System
A professional high-current generator designed for AC and DC primary injection testing of breakers, busbars, CTs, and protection systems. Built for industrial and substation applications, it delivers stable, high-output current for commissioning and maintenance diagnostics.
Description
This high-current generator is engineered for primary injection testing across electrical distribution systems, substations, and industrial power networks.
Designed to deliver substantial AC and DC test current, the unit is used to verify:
-
Circuit breaker trip characteristics
-
Busbar and joint integrity
-
Current transformer (CT) performance
-
Protection relay operation under real load conditions
-
Overcurrent protection systems
Primary injection testing is essential for confirming correct operation of protective devices under actual current conditions rather than simulated secondary signals. This makes the instrument suitable for commissioning, preventive maintenance, and fault investigation.
The system features a digital display for monitoring output parameters and test results. Its robust construction supports use in demanding industrial environments.
Portable and field-ready, it is intended for professional electrical testing personnel working in substations, utilities, heavy industry, and large commercial facilities.
