METHOD OF TESTING A SPUR SHORT CIRCUIT PROTECTION SYSTEM AND DIAGNOSTIC DEVICE FOR PERFORMING THE METHOD |
摘要 |
<p>A method of testing a short circuit protection system applied to a spur of an electric circuit, in which the short circuit protection system comprises a current limiting means which applies a current limit to said spur if the current thereon exceeds a spur current trip level, in which the electric circuit comprises 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, in which said method comprises the following steps: i) applying a test current demand to said short circuit protection system which has a current and duration sufficient for said spur current trip level to be exceeded, but a current insufficient for said power supply trip level to be exceeded and/or a duration insufficient to exceed said deadband period, ii) detecting if the current limiting means applies said current limit or not during said test current demand.</p> |
