The Eaton Cooper Power series Type MET electronic recloser control tester is designed specifically for testing Type ME Form 2, Form 3, Form 3A, Form 4A and Form 4C controls.
The tester has the capability to check the following:
1. Battery voltage (load and no load).
2. Battery charge and discharge rates.
3. Minimum-trip current, phase and ground (low range to
5 amp ground).
4. Operating sequence.
5. Control response time (phase and ground trip).
6. Reclosing time.
7. Reset time.
8. Electrical operation of recloser.
9. Various accessory functions through simulation of the
conditions under which they operate.
The self-contained unit is compactly packaged in a sturdy, weather-proof carrying case with a detachable front cover. Cables for connecting the recloser, electronic control, and control battery to the tester are supplied with the tester and stored in the carrying case along with spare fuses and bulbs for panel lights. No other external equipment or accessories are required when using the tester.
A recloser-simulator circuit is built into the 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.
