Digital Insulation Resistance Tester Measurement Considerations

The digital insulation resistance tester adopts embedded industrial single-chip microcomputer real-time operating system. Digital analog hands and digital segment display are combined perfectly. This series of watches has a variety of voltage output levels (2500V, 5000V, 10000V), strong anti-interference, analog pointer and digital Simultaneous display, AC/DC dual-use, simple operation, and automatic saving of measurement results are ideal test instruments for measuring insulation resistance of transformers, transformers, generators, high-voltage motors, lightning arresters, etc.
The digital insulation resistance tester must pay attention to the following matters in the measurement:
1. It is forbidden to measure the insulation resistance at the time of lightning or near the high voltage equipment. Only the equipment is not charged. It is also measured without induction.
2, during the measurement process. No personnel can work on the device under test.
3, insulation resistance tester output connection can not be twisted together. Must be separated.
4. Before the hand crank megger has not stopped rotating or the device under test is not discharged. Do not touch it with your hands. Do not touch the metal part of the lead when removing the thread.
5, the end of the measurement. For large-capacity equipment to put * electricity.
6. The insulation resistance of the measuring cord led from the terminal of the insulation resistance tester should be good. The proper distance should be maintained between the two wires and between the wire and the ground so as not to affect the measurement accuracy.
7. In order to prevent leakage resistance of the device under test, use an insulation resistance tester. The middle layer of the device under test (such as the inner insulation between the cable cores) should be connected to the protection ring.
8, insulation resistance tester to regularly verify its accuracy.
