The main applicable scenarios of Partial Discharge Tester
On site insulation testing of power equipment (transformers, GIS, cables, etc.)
Development and Type Testing of High Voltage Electrical Products
Quality monitoring and factory testing during the manufacturing process
Teaching experiments and insulation research in research institutions and universities
Why is a Partial Discharge Tester needed? --Addressing the three core pain points
Prevent in advance: Accurately capture weak discharge signals before equipment breakdown or explosion, and transform passive maintenance into proactive predictive maintenance.
Reduce operation and maintenance costs: Reduce the frequency of regular power outages and maintenance, and avoid high repair costs and production downtime losses caused by sudden failures.
Ensuring personnel safety: Non contact detection keeps you away from high voltage hazards and avoids safety accidents caused by sudden equipment failures.
Technical advantages of Partial Discharge Tester
1. High sensitivity and wide range adaptability: covering pC level discharge detection, supporting multiple sample capacitance and current ranges.
2. Unique dual channel simultaneous measurement function: It can easily measure multiple samples simultaneously or multiple points of a single sample simultaneously, making it possible to diagnose the discharge part of large transformers
3. Portable and site friendly: Small in size, lightweight, with battery power supply capability, suitable for on-site environments such as substations and factories.
4. Waveform display and time window function: Elliptical/linear dual-mode display, time window can be flexibly set, which helps to separate complex signals and suppress interference.
The partial discharge detection system is suitable for:
- Power transformer
- GIS (Gas Insulated Switchgear)
- Switchgear
- Cables and cable accessories
- Generator, electric motor
- High voltage testing equipment

FAQ
Q1: Can this detector really detect early weak discharges? Will it be missed?
A1: Sure. We adopt a multi technology fusion scheme (high-frequency, ultra-high frequency, ultrasonic, transient ground voltage), which can detect a minimum discharge signal of 1 picocoulomb (pC) level, far below the danger threshold of equipment insulation degradation. At the same time, it is equipped with an intelligent anti-interference algorithm to effectively filter out environmental noise, ensuring that real discharge is not missed, and the false alarm rate is controlled below 5%. In practical applications, multiple internal insulation defects of switchgear have been successfully alerted 3-6 months in advance.
Q2: The on-site interference is very serious (corona, mobile phone signal, motor frequency conversion, etc.), can the instrument accurately distinguish?
A2: Yes. The partial discharge tester is equipped with triple anti-interference technology including pulse grouping analysis, spectrum filtering, and phase synchronization tracking. And provide PRPD (Phase Decomposition) spectra and waveform time-frequency diagrams, making it clear at a glance the differences in phase, amplitude, and frequency spectrum between discharge signals and interference signals. You can also customize the "noise library" to allow the instrument to automatically learn typical on-site interference, further reducing false alarms.
Q3: Is the operation complicated? Can our frontline employees use it without professional training?
A3: Very simple. The whole machine adopts fully English one click intelligent measurement, and the instrument automatically matches sensors, adjusts gains, sets thresholds, and displays real-time "normal/attention/alarm" conclusions. We also provide a 15 minute quick start guide and free training to ensure that zero foundation employees can use it on the same day.
