TEV and AE method is acknowledged and suitable technology to be used in online partial discharge detection.GDPD-313M uses ultrasonic detection technology (AE) and TEV mode, which can effectively ensure signal sensitivity in the interference on-site environment. It is suitable to detect PD flaw and locate PD signal for switch cabinet etc.Product Features:-● Built-in ultrasonic sensor. electrical fault generates ultrasonic wave at the fault point, and ultrasonic mode transmits the ultrasonic signal through the earphone to scan the area to detect the discharge. Various characteristics of vibration, pop, and hum can be associated with different faults.● Built-in high-precision TEV sensor, coupled with electromagnetic signals generated by partial discharge, to identify potential internal discharge failure risks.● In Ultra Mode, the main interface displays the partial discharge amplitude (dBuv), and uses the yellow, green, and red colors to increase the severity of the partial discharge. At the same time, the headphone listening volume (Vol) can be adjusted.● In the transient radio mode (TEV Mode), the main interface displays the partial discharge amplitude, the number of pulses, the total number of pulses and the discharge intensity level in each power frequency cycle.● Powered by rechargeable lithium battery, continuous working for more than 6 hours.● True color LCD display, real-time battery power prompt; physical film button is easy to use and equipped with external high-fidelity noise reducing headphones.Specifications:-●TEV SensorMeasurement range0-60dBBandwidth3-100MHzAccuracy±1dBMax. pulse times per cycle1000Min. pulse times1● Ultrasonic sensorMeasurement range-7dB~60dBResolution1dBAccuracy±1dBSensitivity-65dBCenter frequency40.0±1.0KHzBandwidth2.0KHz● BatteryBuilt-in batteryLithium battery, 8.4V, 1800mAhUse timeAbout 6hoursCharging timeAbout 5hoursProtectionOver-voltage and over-current protection● ChargerRated voltage8.4VOutput current1ATemperature10℃-60℃Humidity<80%● HardwareShellMonochrome molding plasticScreen240*320 TFT LCD screenControl6 buttonsInterfaceMicro USB interface, charger port, headphone port, external port for collecting wave collectorHeadphoneHigh fidelity noise canceling headphones● DimensionSize178mm×75mm×30mmWeight0.25KGCase size415mm×330mm×170mmCase weight2.3KGTotal weight2.7KG● Working environmentUse temperature-20℃~50℃Environmental humidity0-90%RHIP class54Buy ultrasonic PD tester online in India at wholesale rates.
