TH2882A series impulse winding tester, adopting high-speed sampling technique, is a new generation analysis test instrument for insulation performance of coil products.When testing, TH2882A compares the standard waveform stored in the instrument with current measuring waveform. TH2882A gives the PASS or FAIL comparison result according to Area, Differential Area, Corona Discharge, Differential Phase etc. With strong function, precision test method, flexible operation and various interfaces, TH2882A can provide test solution for most coil winding products.The impulse winding tester tests the electrical characteristics of coil winding without damaging the DUT. The prerequisite conditions for quality of a coil can be detected at just a glance. The detection is carried out when the same electric impulse by capacitor discharge is applied to the standard and the DUT. The voltage decay waveform is generated in response to the impulse, related to the Q-factor and inductance of the coil. In this sense, the tester can detect turn & layer short, the differences in the number of turns and the material of the core. If high impulse voltage is applied, the poor insulation will appear as a corona or layer discharge.Technical ParameterModelTH2882A-3TH2882A-5TH2882AS-5Output ImpulseVoltage300V-3000V, 50V Steps± 5% of set value ± 15V500V-5000V, 100V Steps ± 5% of set value± 25VVoltage ControlModeNormalVoltage programmable at the measurement terminals when terminals openedConstantMaintaining selected voltage across the winding independent of changes of the winding impedanceImpulse Energy(1K ohm Resistive Load)≤ Max. 90 milli-Joules≤ Max. 250 milli-JoulesType of CoilSingle-phaseThree-phase three-wire systemThree-phase four-wire systemInductance Range≥ 10μH≥ 20μH≥ 200μHDisplayScreenMode320x240 dots LCDWaveform Display Dots240x200 dotsDisplayInformationSetting parameter, Standard & measuring waveform, Measurement & comparison resultWaveformSamplingSampling Rate40MSPS/25ns, 20MSPS/50ns, 10MSPS/100ns, 5MSPS/200ns, 2.5MSPS/400ns, 1.25MSPS/800ns, 625kSPS/1.6μs, 312kSPS/3.2μsResolutiondigitsSampling LengthBytesInput Impedance10MΩ (Resistive voltage divider)Measuring Speed5.5 times/sec (Waveform display OFF, PASS/FAIL ON)3.3 times/sec (Waveform display ON, PASS/FAIL ON)Average Rate1-99, ProgrammableWaveform MeasurementVoltage, Time, FrequencyTrigger ModeInternal/Manual (Foot)/External/ BUSComparison ModeArea size comparison, Differential area comparison, Corona discharge differential phase comparisonArea Size Repetition Accuracy±1%Differential Area RepetitionAccuracy±1%Detection OutputPASS/FAIL display, AlarmAlarm VolumeLong high, Long low, Single low, Double low, OffMemorygroups of standard waveform data can bestored in internal non-volatile memory 500 groups in USB flash memory (optional)InterfaceHANDLER (Start, Stop, Pass NG, Busy, EOC, etc.),RS232C, GPIB(optional)Chuangkai Electronic Co., Ltd is leading company specialized in producing, developing & selling various types of measuring instruments and testing equipment, such as temperature data logger, LCR meter, DC resistance tester (micro ohm meter), digital power meter, power supply, transformer tester, battery tester, programmable DC electronic load, charger, temperature controller, tachometer, high voltage signal-amplifier, power amplifier, etc.FAQ:Q.
