Product Description Partial Discharge Detector Calibration System PD Test Equipment Calibration Tool Know about Partial Discharge TestingPartial Discharge Testing BasicsTo understand partial discharge testing, it's best to first understand partial discharge. Partial discharge can be described as small electrical sparks that occur in stator windings whenever there are small air gaps or voids in or around the insulation. Once sparking occurs, the stator windings start to deteriorate. The larger the void in insulation, the larger the possible discharge resulting in possible machine failure.Why Does Partial Discharge Testing Matter?Partial discharge testing is a leading indicator of machine failure. If left undetected, it can eventually lead to complete deterioration of the electrical insulation which is one of the principal causes for forced outages of generators and motors.Using online monitoring to identify partial discharge can help avoid service failures, extend the time between rewinds and outages and plan maintenance based on machine condition.Know about Partial Discharge Detector Calibration SystemPartial discharge testers are used to detect and evaluate partial discharge phenomena in electrical equipment to assess the insulation condition and performance of the equipment. To ensure the accuracy and reliability of the testers, it is important that they are calibrated and aligned on a regular basis.A partial discharge tester calibration device is a specially designed device that simulates and generates a known partial discharge signal for calibration and verification of the tester. It typically consists of a source that generates the partial discharge signal, as well as interfaces and controls to the tester.During the calibration process, the partial discharge tester is connected to the calibration device and calibrated against predetermined standards and parameters. The calibration device generates known partial discharge signals, which are measured and analyzed by the tester and compared with the expected results. Based on the comparison results, necessary adjustments and calibrations can be made to ensure the accuracy and reliability of the tester.By using a partial discharge tester calibration device, the measurement accuracy of the tester can be verified and ensured that it can accurately detect and assess partial discharge phenomena in equipment. This helps to improve the reliability and accuracy of insulation condition assessment and preventive maintenance work on equipment.Unique Selling Points (USPs)JFJZ-1 type partial discharge tester calibration device (here-in-after referred to as the calibration device) can be used to calibrate the measurement functions such as cut-off frequency, linearity, range scale consistency, pulse polarity corresponding, 25Hz pulse response, measurement sensitivity and coupling device calibration of the partial discharge tester based on pulse current method in the current market.Technical characteristics Use of environmental requirementsTemperature: 10°C~30°CRelative humidity: <80% (25°C) Sea level: <2500mPower supply voltage220V±5VPower frequency50Hz±0.5Hz,Mechanical vibration: undetectableCharge calibration module1.Charge calibration range:0.1pC~100nC.2.Square wave peak range:-100V~100V.3.Waveform rise time: 20ns.4.Charge calibration accuracy: 2%.5.Calibration capacitance: 10pF, 20pF, 50pF, 100pF, 200pF, 500pF, 1000pF, 2000pF, 5000pF (programmable switching).Signal generation moduleSine signal generation module1.Frequency amplitude: 25Hz~1MHz.2.Voltage amplitude: 0V~10V (peak).3.Voltage accuracy error: 2%.4.Frequency error: 0.1%.Dual pulse generation module1.Dual calibration pulse time delay adjustable range: 0.1us~250us, precision: 0.01us, duty cycle 50%.2.Repetition frequency range: 1Hz~3kHz.3.Rise time: 15ns.4.Output impedance: 50Ω.5.With counting pulse output function.
