• Computerized recloser time current curve verification program
• Receive test results from three different sources
• Save test results for further analysis
• Store three separate current levels and minimum pickup for each recloser

TCC is a computerized recloser time current curve verification program designed to streamline the time current curve verification process. TCC automatically calculates the allowable envelope and displays the minimum, maximum, optimum, and actual times for each trip operation.

The software accomplishes this by interpolating between time current curve data points (digitized from actual tcc’s) to determine the corresponding times for each amperage. The envelope is determined by calculating the acceptable variations of time and current according to the manufacturers specifications. The actual trip times of each operation are compared to these calculated minimum and maximum values to determine if the recloser is within allowable tolerances. TCC uses this information to provide
a “GO/NOGO” result to the operator.

TCC software can receive test results from three different sources. Time and current can be entered manually, the TCC software can communicate directly with the optional ORTMASTER module via the parallel port, or the TCC software can communicate directly with a Multi-Amp Oil Circuit Recloser Test System via the RS-232 computer interface. If the Multi-Amp Oil Circuit Recloser Test System does not have a RS-232 computer interface, an upgrade kit is available. See the Time Current Curve ORTMASTER bulletin for more information on the ORTMASTER interface module.
