The Cooper Power Systems Type MET Electronic Recloser Control Tester is designed specifically for testing Type ME Form 2, Form 3, Form 3A, Form 4A, Form 4C, Form 4D, Form 5, Form 6, Types FX, FXA, and FXB controls.
The self-contained Cooper Recloser Tester comes in a weather-proof carrying case with a detachable front cover, and includes cables for connecting the recloser, electronic control, and control battery to the tester. No other external equipment or accessories are required when using the tester.
The MET has the ability to check operation of the electronic recloser control and can also check the electrical operation of the recloser (provided reclosing power is available at the recloser). However, the control cannot operate the recloser through the tester.
A recloser-simulator circuit is built into the Cooper Tester to simulate recloser operation (indicated by red and green lights on the tester panel) and to simulate the response time of the recloser mechanism to trip and close signals. The recloser simulator provides a 2-1/2-cycles time delay to duplicate the interrupting time of a Type RE recloser in response to a trip signal from the control when recloser clearing time tests are being conducted. It also provides a time delay of approximately 30 cycles to duplicate the response time of a Type RE or WE recloser to a reclosing signal from the control when reclosing time tests are being conducted.
