Coil Analyzer

Powerful breaker coils analyzers

Coil Analyzers SAT series instruments are powerful units ideal for testing of circuit breakers, where substation battery is not connected or available. The SAT series instruments are intended to operate breaker coils, and spring charging motors as a part of commissioning and maintenance testing.
Coil Analyzers can measure current and resistance of circuit breaker coils. SAT series instruments can also be used to test minimum trip voltage of circuit breaker coils, as well as under voltage releases of circuit breaker.

The minimum trip voltage test is described in a number of international and national standards such as IEC 62271-100, ANSI C37.09 etc. Many other important parameters are possible to test with Coil Analyzers. They are compatible with breaker analyzers from different vendors.

Typical applications:

  • operating circuit breakers
  • supplying spring-charging motors
  • coils resistance measurement
  • coils current measurement
  • minimum trip voltage-test of the circuit breakers coils
  • undervoltage release test
  • power supply at test with breaker analyzers
