CABLE IDENTIFICATION POTENTIAL EXTRASION TESTER PRECAUTIONS 1. Cable IDENTIFICATION 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, which leads to misjudgment and insulating surfaces will form capacitors. When the measuring rod is in contact, there is a large discharge current, which leads to misjudgment.
2. 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. Cable Identification Instrument Potential Transformation Tester Performance Characteristics Cable identification instrument is an insulation test method used to detect insulation defects of generator stator bars.
The compactness and relative dielectric strength of the stator end insulation are detected by detecting the external displacement potential of the end face of the generator stator coil. Insulation supervision is applied to the ends of the coils, and lead packages are also found to have various insulations. It can make up for the shortage of end insulation defects that cannot be found in the AC and DC withstand voltage test of the generator stator winding.
The reliability of the safe operation of the generator is further improved. Cable identification instrument submersible displacement tester functions: 1. The instrument is powered by the built-in power supply, no external power supply is required 2. The standard digital meter can visually display the external potential reading of the product under test, and it is intuitive. Surface potential distribution is used to monitor end insulation.
3. The independent self-selected combination connection is very convenient for testing needs.
