  • INQUIRY

First of all, let's understand what is a partial discharge.

According to the definition of the International Electrotechnical Commission IEC 60270, partial discharge (PD) is a localized electrical discharge that only partially bridges the insulation between conductors and which may or may not occur adjacent to a conductor.

The harm of partial discharge to insulation includes the following aspects:

1. Charged particles (electrons, ions, etc.) impacting on insulation and destroying its molecular structure, which results in insulation damage;

2. Because of the impact of charged ions, the partial temperature of insulation rises, which easily leads to insulation overheating and carbonization in serious cases;

3. The continuous development of partial discharge will lead to insulation deterioration. The damage gradually enlarges, and ultimately shortens the normal life of insulation, reduces the short-term insulation strength, and may even cause the whole insulation to break down.




GTPD-3 handheld Patrol Ultrasonic partial discharge tester brief introduction:

GTPD-3 partial discharge tester is a detection device which can diagnose hidden trouble of power line by collecting and analyzing the abnormal ultrasonic signal of power line. It is also suitable for partial discharge detection of insulator, cable terminal, high voltage bushing, CT\ PT, lightning arrester, switch, etc. This device realizes the location and type of fault hidden danger with the power line and equipment in live state.



Functions and Feature

1. Portable design, small size, light weight, easy to carry. It can be working on vehicles with a speed of 30km/h.

2. It is easy to locate, focus and take photos on the fault of the equipment through camera and laser detector,

3. The screen of GTPD-3 partial discharge tester is a color touch type, which can display waveforms, dB values, temperature, humidity and GPS information.

4. The detected abnormal ultrasonic signal can be converted into audible sound signal and waveform output.

5. Embedded GPS receiver automatically stores coordinate data and provides GPS navigation function to facilitate inquiry and preservation of detection paths.

6. GTPD-3 partial discharge tester has the function of detecting temperature and humidity, and can detect temperature and humidity in real time.

7. With data storage function, data playback can be realized.

8. High sensitivity, directivity , it can locate the fault accurately.

9. GTPD-3 partial discharge tester is suitable for noise environment and is not affected by environmental noise.

10.Early detection of faults can be detected prior to other detection methods such as infrared detection.

11. By the non-contact live detection method, detection distance of partial discharge tester can reach to more than 30 meters, safe and reliable, without affecting the normal operation of equipment.
