HZYA-3Z Transformer On Load Tap Changer Oltc Tester
The Transformer On-Load Tap Changer (OLTC) Parameter Tester is a specialized instrument designed for measuring and analyzing the operating characteristics of transformer on-load tap changers.
It can test key parameters of the on-load tap changer, including its transition process, transition waveform, transition time, transient resistance, and three-phase synchronism.

Features
1. Large output current, light weight;
2. Test YO, Y, △ 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.
