Product description 3 phase capacitance and inductance tester is developed for the problems of capacitance value, and it solves the following problems Field measurement capacitor needs dismantling cables, not only the big workload but also easy to damage the capacitor. Low capacitance meter output voltage causes the fault detection rate is low. The instrument has characteristics of small measured workload, fast and simple, stable performance, high measurement accuracy, high fault detection, etc. Reactor inductance measurement. Technical parameters Working power supply Rated voltage power frequency of 220 V10 The rated frequency 50Hz The rated output 2V 20V 500VA Equipment normal working conditions Environmental temperature 10 50 Relative humidity 90 Display and print mode LCD display with Chinese characters Panel high speed printer Shape weight 370 260 220 mm 15 kg 5. Work principle as shown in figure 1 3 phase capacitance and inductance tester Feature The inductance capacitance tester adopts the bridge circuit structure, the standard capacitor and tested capacitor as two arms of the bridge circuit. When conducting the capacitor capacitance value measurement, test voltage applies on the standard capacitor and tested capacitor at the same time. Processor obtains capacitance value of tested capacitor by sensors with acquisition the current signals through the two capacitors after processing. Due to adopting the standard capacitor, tested capacitor synchronous sampling technology, it may not affected by the power supply voltage fluctuation; Combined with the measurement process is fully automatic, which avoids the error due to manual operation, so it has the characteristics of good stability, good repeatability, accurate and reliable, the machine has tested object automatic identification and short circuit protection function.
