XHYZ1668 On-load tap changer tester
Product description
The instrument is mainly used to measure the transition waveform, transition time, instantaneous transition resistance value, and three-phase synchronicity of transformer on-load tap-changer.
2. Features
The instrument has large output current and light weight;
★Test YN, Y, △ transformers, the resistance value can be displayed directly without conversion, and can be measured with windings.
★The waveform display automatically adjusts the resistance, time value and amplitude according to the sampling value
★It has perfect protection circuit and strong reliability;
★7-inch LCD display, easy to operate on site;
★ 500 groups of data , automatically saved inside.
★Sampling rate 20KHZ.
★Built-in large-capacity lithium battery, external power supply is not required.
