Connecting High-voltage Leads to a Motor
NOTE: Before you connect leads to a motor for any test, collect information about the motor you want to test
(for example, motor name plate information). We highly recommend you do this to efficiently set up the test
and to ensure you compile accurate test records, but of course you will also need part of the information to
determine test voltages needed.
High-voltage leads are used during DC and Surge testing. The connections described here are
for three-phase testing mode.
1. Ensure motor leads are properly labeled to provide accurate test data.
2. Connect the high-voltage test leads to each of the motor leads. Motor lead 1 connects
to test lead 1, motor lead 2 connects to test lead 2, and motor lead 3 connects to test
lead 3.
3. Connect the ground cable to motor ground.
4. Ensure test/motor leads do not contact each other or the motor chassis during testing.
