TEST-905 PORTABLE 5000A PRIMARY CURRENT INJECTION TEST SYSTEM FOR CIRCUIT BREAKER TESTING

Portable 5000A Primary Current Injection Test System for Circuit Breaker Testing
The TEST-905 primary current injection test system is a high-performance, portable device designed to meet the demanding requirements of electrical testing in power systems. It utilizes an advanced ARM chip to control the output process and features a large-capacity toroidal transformer for reliable performance. The system includes an LCD screen that displays the primary current value, secondary current value, turns ratio, and phase shift, making it easy to monitor and adjust during testing.
Built with an aluminum alloy body and a PC panel shell, the TEST-905 is both durable and lightweight, suitable for on-site or laboratory use. It is ideal for testing CT turn ratios, polarity, contact resistance, high-voltage circuit breaker protection, and high-voltage generator tests, where large currents are required.

FEATURES
