Introduction

Partial Discharge For GIS UHF Sensor PD Detector Manufacturer In China 

 

  

 

Partial discharge does not cause the electric discharge of a completely short-circuited electrode. Such discharge usually has a very small amplitude value, but it will certainly cause the continuous deterioration of the property of the insulation layer and finally cause electric equipment fault. The non-intrusive partial discharge detection, as a convenient and simple method, is used for identifying the potential insulation faults which may cause power cutoff or personal injury. The partial discharge emits energy in following manners: Electromagnetic energy: radio wave, light and heat; Sound energy: sound wave and ultrasonic wave; Gas: ozone and nitric oxide. The most practical non-intrusive detection technologies are all based on the detection of the high-frequency signals and the ultrasonic signals in the electromagnetic spectrum. The product is an instrument which has simple operation and is specially developed for detecting the activities of electromagnetic waves and ultrasonic waves.

Technology Parameters

1. Applicable scope: the non-intrusive mode is adopted to detect and locate the partial discharge defects of the high-voltage electric equipment. 2. sensor configuration Standard: UA, TEV Optional: Sensor network for transformer, high frequency sensor for GIS, sensor for high-voltage cable,or other senors customized according to user's requirements. 3. Detection principle: UHF (Ultra High Frequency) method, UA (Ultrasonic Analysis) method and TEV (Transient Earth Voltage) method. 4. Detection frequency band: UA: 40200KHz TEV: 3~100MHz UHF: 3002000MHz. 5. Measurement range: UA: -9080dB TEV: -8010dBm UHF: -8010dBm. 6. Sensitivity: the minimum sensitivity is 10pC (specifically determined by the distance between the sensor and the discharge source). 7. Sensor: a) Ultrasonic sensor: 20200(kHz); b) EV (Transient Earth Voltage) sensor: 5 ~ 100MHz; c) UHF sensor: 3002000(MHz), with directional reception characteristic. 8. Embedded ultrasonic sensor and TEV & UA integrated sensor: such components as transformer dedicated sensor, GIS dedicated sensor and cable dedicated sensor can be selected; 7 9. Software function: a) Continuously detect UHF, TEV and ultrasonic signals to judge whether there is any partial discharge; b) Display the variation tendency of the detected signal in a real-time manner to intuitionally judge the development of the partial discharge signal; c) Field data storage function; 10. Instrument characteristics: a) Screen display: high-contrast 3.5"TFT color screen. b) Data storage: 1000 groups of test data can be stored. c) Working power supply: embedded 8.4V lithium battery for 8h's continuous operation. d) Power supply: input 100-240VAC, output 8.4V/3A, charging time 34h. e) Boundary dimension: 220 * 100 * 40. f) Instrument weight: 1.5kg. g) Environment temperature: -2545. h) Storage temperature: -3560.
