Manufacturer Price Pd free Hipot Tester Partial Discharge Detection System AC Withstand Voltage for Cables GIS
Oscillating Wave Partial Discharge Testing System
1) The bulky testing equipment under power frequency voltage makes it difficult to conduct on-site testing.
2) The credibility of ultra-low frequency detection results and the damage to cables.
3) The insecurity caused by DC DAC on cables.
4) It can not only complete AC withstand voltage tests, but also achieve partial discharge testing and fault location.
Classification Features | Disadvantages | Advantages |
Partial discharge detection equipment under power frequency voltage | High power is required during testing; The testing equipment is bulky and difficult to conduct on-site testing; | 1. The equipment is the most ideal and closest test equipment to the operating environment; |
Partial discharge detection equipment under ultra-low frequency voltage | The credibility of the detection results and the damage to the cables;
The application of PD detection is relatively limited; | There is no need for high power during the experiment;
The weight and volume of the equipment decrease relative to the power frequency; |
Partial discharge detection equipment under DC damping oscillation wave voltage | Under DC voltage, XLPE cables will generate a "memory" effect and accumulate unipolar residual charges;
Surface flashover or breakdown of cable accessories at cable terminals can cause wave oscillation on the cable core and damage the main insulation;
Water branches inside the cable will quickly transform into electrical branches under DC voltage and form discharge; | The AC power method has good equivalence, short action time, convenient operation, and is easy to carry;
The test will not cause damage to the cable and other characteristics; |
Partial discharge detection equipment under damped oscillation wave voltage | 1. Based on the principle of resonance, it effectively solves the bulky and difficult on-site detection of detection equipment under power frequency voltage.
2. The frequency range is 20-400Hz, which is higher than the reliability of ultra-low frequency detection results and the damage to cables.
3. The system has pure AC voltage to avoid the insecurity caused by DC DAC on cables.
4. It can not only complete AC withstand voltage tests, but also achieve partial discharge testing and fault location. |

System software functions
1) This system is suitable for on-site PD detection and positioning of cables with voltage levels of 10kV and below.
2) The collection part of this system implements wireless data collection, enhancing the security of the system and operators.
3) This system provides parameter setting module, signal acquisition module, data analysis and spectrum display, data storage, offline data review, analysis, processing and calculation of discharge position, and can locate partial discharge faults.
4) This system provides functions such as discharge spectrum, fault location spectrum, discharge phase spectrum, discharge frequency spectrum, and discharge type identification.
5) This system has anti-interference functions such as digital filtering, dynamic threshold, wavelet analysis, time delay discrimination, correlation analysis, etc. It can select and distinguish discharge pulses and interference pulses based on signal characteristics, as well as PD type recognition through simple pattern recognition.
6) The system determines the type of partial discharge according to the relationship between the damped oscillation voltage waveform and the partial discharge signal as well as the positioning spectrum, so as to make more effective assessment and prediction of the overall insulation condition and life of the cable.
