9.1.2 Timing an OPEN Operation with Insertion Resistors
The CT-6500 can time breakers with insertion resistors. The insertion resistor can
range from 10 to 7,000 Ohms. Any insertion resistor more than 7,000 Ohms is detected as
an open circuit. The timing results will show the main contact time and the insertion
resistor contact time. Graphic reports will show the main contact and the resistor contact
activities on each of the channels.
