GDPD-306M is widely used in the partial discharge detection of power systems. Including high voltage switchgear, ring mains, voltage/current transformer, transformer (include dry type transformer), GIS, overhead lines, cables, and other equipment insulation state detection. Product Details:-The following indicators are used to measure the degree of discharge of electrical equipment:Partial discharge intensity detection: By measuring the discharge signal in a power frequency cycle, the intensity of the partial discharge is characterized according to the maximum value (dB) in the discharge pulse sequence.Partial discharge frequency detection: The device measures the discharge signal within a power frequency cycle, extracts the discharge pulses and characterizes the frequency of partial discharges according to the number of discharge pulses.● With different sensors to achieve partial discharge detection of almost all electrical equipment.● Provide multiple discharge patterns such as time-domain waveform, PRPD, PRPS, etc., to realize the analysis of different discharge types.● User-friendly man-machine interface facilitates the data management of different devices, including the traceability of historical data change trends, horizontal and vertical data analysis, and realizes a 360° comprehensive diagnosis of the tested device.● Built-in ultrasonic sensor and transient earth voltage (hereinafter referred to as TEV) sensor, also can be connected to external special sensors for transformers, GIS, overhead lines, and cables.● It adopts non-intrusive detection method, no need to power off during the test process, no need to configure additional high voltage source, it is more convenient to use than traditional pulsed partial discharge detector.● The test bandwidth range is 30kHz ~ 2.0GHz, suitable for detection principles of various frequency bands.Specifications:-TEV MeasurementUHF MeasurementMeasurement range0-60dBmVDetection frequency band300~1500MHzResolution1dBMeasurement range-75-0dBmVAccuracy±1dBAccuracy<1dBmVMax. pulse per cycle1400Sensor frequency band300-2000MHzMeasurement frequency band1~100MHz AA measurementAE measurementMeasurement range-6dBμV~68dBμVMeasurement range-6dBμV~68dBμVResolution1dBResolution1dBAccuracy±1dBAccuracy±1dBSensor center frequency40kHzFrequency range40-200kHzHFCT measurementSensor transmission impedance5mV/mADetection frequency1~30MHzSensitivity≤50pCHardwareShellABSDisplay4.0inch RGB LCD screenControllerARMConnectorUSB interface (charger port), Wireless WIFI3.5mm stereo headphone jack, Wireless synchronization benchmarkExternal ultrasonic sensor inputHeadphone8ohm minimumSD cardStandard 16GBuilt-in battery3.7V/1Ah lithium batteryWorking timeAbout 8 hoursChargerAC 90-264V or DC 5VWorking temperatures-20~ 50℃Humidity20~85% relative humidityDimension, weight210*100*35(mm), 0.4kg (main unit)Buy Portable Ultrasonic Partial Discharge Detector online in India at wholesale rates.
