This article reports on testing done on the circuit breaker test set UPA-20 by KEP. The testing procedures were divided into two main stages. The quality assurance (QA) team started with checking the accuracy of current setting on the Circuit Breaker Test Set UPA-20. For this purpose they set one by one the output current values of 4 кА, 6 кА, 10 кА, 12 кА, and compared the UPA readings with those of the reference meters (the current transformer and the comparator measuring current on the current transformer) Having made sure the actual values of the current fed by the test set match the ones set by the user, the QA team conducted a sample test of a circuit breaker. Generally, circuit breaker testing is done in the time of 0.1 seconds to find out at what current value the circuit breaker trips and at what current value it does not trip in that time. Based on the testing results the user can assess whether the circuit breaker has passed the testing or failed it. The circuit breaker test set UPA-20 has a mode in which the user can set the current to be fed. For this type of testing, the user sets the time duration in which the device will be feeding the set current (the available UPA-20 modes are 100 ms, 200 ms, 400 ms, 600 ms, 800 ms, 990 ms and 10 seconds). Once this time is over, the UPA will stop the current supply. In this sample test the circuit breaker tripped at a current of 8.8 kA and time of 480 ms. Based on the testing results the QA team has concluded that the UPA-20 by KEP has proved to be a reliable circuit breaker test system with accurate current setting capability and an intuitive user interface. In addition, the test set's portable design makes it possible to conduct circuit breaker testing with ease and flexibility that are especially valuable for field testing.
