Question: Cable Identifier Performance Characteristics Answer: Cable Identifier is an insulation test method used to detect insulation defects in generator stator bars. The compact problem of detecting stator end insulation by detecting the external displacement potential of the end face of the generator stator coil: cable identifier performance characteristics Answer: The cable identifier is an insulation test method used to detect insulation defects in 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 function: 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.
Technical parameters of generator potential transformation tester. 1. Test voltage: DC0-30KV 2. Standard length: 1.6 meters. 3. Input resistance 100M 4. Voltage display mode: LCD window display 5. Weight: 1.5Kg Main features of cable identifier Test; 2. Strong anti-interference ability: Even in a 500KV substation environment, it can measure the high-frequency current generated by itself to filter the 50Hz, 100Hz and other harmonic interference currents in the main power supply; 3. Wide measurement range and high resolution : the range is 0.01Ωto 200Ω, with a resolution of 0.01Ω, the ground resistance is less than 0.7Ωcan also be measured accurately.
4. Large jaw design: The jaw diameter is 50mm (standard configuration), which can meet the requirements of using flat iron/steel as the ground lead. Special jaw size can be customized according to customer requirements. 5. Large-capacity data storage: It can store 200 sets of measurement data; 6. Simple operation, one-handed work: All Chinese operation interface, small size, light weight, explosion-proof suitcase, easy to carry on site.
