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.
