1. Be sure to read this manual carefully before using the Water Cooled Generator Insulation Resistance Tester.
2. The water-cooled generator insulation resistance tester should avoid serious vibration.
3. The operator of the water-cooled generator insulation resistance tester should exercise common sense in the use of general electrical equipment or instruments.
4. The water-cooled generator insulation resistance tester can be used indoors and outdoors, but it should be used away from rain, corrosive gases, excessive dust, high temperatures, direct sunlight and other places.
5. Maintenance, maintenance and adjustment of the instrument must be carried out by professionals.
6. Strictly adhere to safe operating procedures.
7. Non-testers should stay away from the top testing areae tension. The testing area should be clearly marked with fences, ropes, warning signs, etc.
8. Touching the test leads during testing is strictly prohibited!
9. After the test is completed, the test terminal must be short-circuited and discharged manually!
There are three terminals to connect to the water shaking meter, 1. L is connected to the winding, 2. Water collection pipe (when the shaking is isolated, the pipe water collection is grounded, open and connected to the water meter) 3. E is connected to the base (reliably grounded). Connect the power supply to the megometer and turn it on. In fact, the ultimate goal is to measure the insulation of the winding at the base of the machine and connect the water pipe. The main reason is that when water flows through the winding, the megometer is powered. Water has a big impact on insulation. For this reason, it is necessarye insert the end of the collector pipe to protect the influence of internal cooling water on the insulation. Simply put, the protection principle is to use the internal principle to short circuit. circuit the conductive effect of water.
