Transformer On-load Tap-changer Tester Fast delivery I 24-hour customer service I customizable Product Introduction HZYA-3Z On-load Tap-changer Tester is the only moving part connected to the transformer circuit. Therefore, the detection of the on-load tap-changer is becoming more and more important. In the "power equipment transfer and preventive test procedures", asked to check the on-load tap-changer action sequence, measurement switching time. The instrument is mainly used to measure the transformer on-load tap-changer transition waveform, transition time, the instantaneous transition resistance, three-phase synchronization and so on. Output current: 2.OAs I.OAs 0.5As 0.2A Measuring range Transition resistance: 0.5Q~5Q(2.0A) 2Q~20Q(1.0A) Transition time: 0 ~ 320ms Open circuit voltage: 24V Measurement accuracy Transition resistance: ± (5% reading ±0.1Q) Transition time: ± (0.1% reading ± 0.2ms) Sampling rate of 20kHz Storage mode U disk storage Dimensions: 340mm x 245mm x 210mm Instrument weight: 7kg 1. Large output current, light weight; 2. Test YO, Y, A type transformer, the resistance unnecessary to be converted but directly display; 3. With winding or without winding measurement; 4. Waveform display automatically adjusts the resistance according to the sampled value, the time value amplitude 5. With perfect protection circuit, reliability and strong; 6.7-inch large LCD display, easy on-site operation; 7. Built-in high-capacity lithium battery(optional) 8.500 sets of data can be saved in Internal automatically, can connect with U Disk.
