摘要
A method of testing a short circuit protection system applied to a spur of an electric circuit. The short circuit protection system has a current limiting means which applies a current limit to the spur if the current thereon exceeds a trip level. The electric circuit has a power supply and an isolation means adapted to fully or partially isolate the power supply from the electric circuit if the current thereon exceeds a power supply trip level for longer than a deadband period. The method includes applying a test current demand to the short circuit protection system which has a current and duration sufficient for the spur current trip level but a current insufficient to exceed the power supply trip level and/or a duration insufficient to exceed the deadband period, and detecting if the current limiting means applies the current limit or not during the test current demand.
