Cable Fault Tester Potential Extrusion Tester Precautions 1. Cable Fault Tester When the end of the foil is wrapped, it must be wrapped tightly, otherwise the foil and insulating surface will form a capacitor. When the measuring rod is in contact, there is a large discharge current, and this cable fault tester potential excursion tester precautions 1. When the end of the foil is wrapped, it must be wrapped tightly, otherwise the foil and The insulating surface will form the capacitor. When the measuring rod is in contact, there is a large discharge current, which leads to misjudgment.
2. Cable fault tester When the end is wrapped, it is divided into the side of the rod and the side of the water pipe. more than 3 cm apart. When the potential is high, it's easy to figure out which side of the problem is.
In fact, the main point is the root and the cone, and the middle part measures the meaning, not much. 3. Microammeter with measuring rod in series *Even if the current is high, it is easy to use a digital microammeter to protect the watch. 4. Since the end fitting is located in the lower part of the case, it is not easy to measure, it is good to lead out lead.
5. It is important to remember the correct abnormal slot number, avoid wearing the crown, remember to remember! 6. To test the generator without water, first blow off the stator cooling water. Features of cable fault tester loss parameter tester: 1. Using 240×The 64-dot-matrix liquid crystal display (with backlight) simultaneously displays three parameters: three-phase voltage, current, low-voltage side voltage, power, power factor, and frequency. 2. It can test the power parameters required for no-load and short-circuit tests.
3. Wide linear range, good repeatability and stable performance. 4. Ensure that the power factor is accurately measured from 0.000 to 1.000, especially for the detection of low power factor loads. 5. Convenient locking ensures the simultaneity of measurement data and the convenience of operation.
