AUTOMATIC CIRCUIT BREAKER TEST SYSTEMSMobile systems for primary injection testing and trip curve control of circuit breakers and overcurrent protection relays.
Testing circuit breakers with real sine-wave current (when using external voltage regulator) yields reliable results of the primary current injection.
The system allows to obtain trip curves of circuit breakers fitted with electromagnetic, thermal and electronic trip elements.
Systems UPA-16 and UPA-20 can perform fixed-duration current injection tests, thus allowing to carry out all test types specified by IEC 60898-1.
This system is equipped with a current source based on a toroidal transformer, featuring optimal thermal performance and relatively low energy consumption.
All modules and accessories making up the system are conveniently mounted on a special trolley, which eases transportation and significantly simplifies the work of an operator.
