Product Description

TEST-901 Portable 1000A Large Current Generator for Circuit Breaker testing with Timer for CIRCUIT BREAKER

TEST-901 1000A primary current injection test set adopts ARM Chip to control its output process and large capacity of toroidal transformers. TEST-9011000A primary current injection test set is equipped with LCD display and current meter; it can show primary current value, second current value, turn ratio and the action time. Packing is used as aluminum alloy body with PC panel. TEST-901 primary current injection test set is mainly applied to CT turn ratio testing in the power system and contact resistance test which need large current.



1. test current transformer
2. test circuit breaker
3. test high voltage switch

Primary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker. The objective of the test is to identify how the system operates under various levels of current load.

Primary injection testing is suitable for testing over-current trip relays attached to a circuit breaker. By injecting the current into the system we can measure if the breaker will trip or fail, and how long the current is live before the circuit is broken.

Circuit breakers can go long periods of time without activation, and failure at the moment of activation can cause catastrophic damage to the electrical system. Circuit breaker testing with primary current injection on a breaker that has not triggered in some time is the best way to recreate the real operating conditions of a current spike.
