Product Description Products Introduce This product can be widely used in partial discharge detection of power system, including insulation state detection of high-voltage switchgear, ring network cabinet, voltage/current transformer, transformer (including dry-type transformer), GIS, overhead lines, cables and other equipment. The discharge degree of electrical and gas equipment is measured by the following indicators: Partial discharge intensity detection: measure the discharge signal within one power frequency cycle, and characterize the partial discharge intensity according to the maximum value (dB) in the discharge pulse sequence. Partial discharge frequency detection: measure the discharge signal within one power frequency cycle, extract the discharge pulse and characterize the frequency of partial discharge according to the number of discharge pulses.TEV measuremeasuring range0-60 dBmVresolving power1dBaccuracy±1dBMaximum pulse per cycle1400Measurement frequency band3-100MHzUHF measurementUHF measurement and detection frequency band300-2000MHzmeasuring range0-60 dBmVaccuracy<1dBmVSensor frequency band300-2000MHzAA measurementmeasuring range-6dBμV~68dBμVresolving power1dBaccuracy±1dBSensor center frequency40 kHzAE measurementmeasuring range-6dBμV ~ 68dBμVresolving power1dBaccuracy±1dBFrequency range20~200 kHzHFCT measureSensor transmission impedance5mV/mADetection frequency1~30MHzsensitivity≤50pCHard wareHousingABSdisplay4.0 inch RGB LCD display resolution: 800* 480connectorUSB interface (also charger input)3.5mm stereo headphone jackexternal sensor input interfaceheadphone8 ohms minimumSD cardstandard 16G ~ 64Gbuilt in battery3.7V/5000mAh lithium batteryworking tiomeabout 6 hourschargerAC 90-264V or DC 5Vusing temperature-20 ~ 50oChumidity20-85% relative humidityvolume and weight210*100*35(mm) 0.4KG(host) Product characteristicsConfigure different sensors to realize partial discharge detection of almost all electrical equipment; Thehumanized man-machine interface facilitates the data management of different equipment; Built in ultrasonic sensor and transient earth voltage (hereinafter referred to as TEV) sensor, which can be externally connected to transformers, GIS, overhead lines, cables and other special sensors; Non intrusive detection mode is adopted, so there is no need to cut off power and configure additional high-voltage source duringthe test, which is more convenient than the traditional pulse type partial discharge detector; The test bandwidth range is 30kHz~2.0GHz, applicable to the detection principle of various frequency bands; Product application field Power generation and distribution enterprisesRailway systemPetrochemical power supply systemAerospace inspection fieldAutomatic detection field
