Recloser and Sectionalizer Test Cables
Test cables for testing distribution reclosers & sectionalizers, including their controllers and switches, are used with the CMC 356/256plus test sets. Each recloser and sectionalizer contains a switch and a controller connected through a basic control cable, provided by the device manufacturer. Each test cable is built with all components necessary to make a direct connection from the test device at one end to the CMC at the other end. Each test package has been designed to allow testing of all functionality that the manufacturer provided in the control cable, including sample test plan(s) and instructions for connecting and using the test cables.
Testing Sectionalizer or Recloser Controllers
These test systems simulate the switch end with all of its voltages, currents, and contacts to give the controller all system condition(s) for which the tester needs to test without changing settings. The functional tests for the controllers include: Current Pick-up levels and timing, Voltage Pick-up & Drop-out levels, Complete Logic Trip Cycles to lock-out sequences, Partial Trip Cycles to confirm No False trips under load currents, Under-frequency Load Shedding logic, Trip-Fail-to-Detect Logic tests, etc.
Testing Sectionalizer or Recloser Switches
These test systems can be connected directly to the recloser/sectionalizer switch and provide the switch with all the voltages, currents, and contacts which it receives from the controller. The system then records the resulting basic timing of the trip and close operations, a & b contact(s) times, and the metered currents and voltages from the switch. The testing allows the collection of data to compare first trip times to subsequent trip times, and, where applicable, allows timing of the spring charging time which can be used to determine if the switch needs additional maintenance.
