WebMethodology. Set the Fluke 1550B to the actual voltage rating of the device. Most ASI Robicon SCRs used on 480 V VFDs (variable frequency drives) are rated at 1400 V. They also use 3000 V devices stacked in series on medium voltage (2300 V and 4160 V) drives. Take two readings, forward and reverse while the device is cold. WebIR measurements are also taken to monitor the insulation ‘health’ of a motor during the installed life and it is important to control the factors which influence IR measurement so that trend can be meaningful. The same test equipment should be used and tests should be done with the motor at a similar temperature and ambient humidity.

WebThe insulation resistance test is the next test that must be done to determine the overall health of the motor. This is done by comparing the resistance between each pair of motor phases and between each motor phase and the frame. This can be done with an insulation tester or megger. The tests must be completed as follows: WebStep 4: Connecting IR Sensor to Arduino. Setting up IR sensor connection to Arduino is very simple. Beside VCC and GND pin, the sensor has only one output pin that should be connected to one of digital pins of the Arduino. In this case it’s connected to pin 13.
