Test transformer |
|
|
| Product name：Test transformer |
| Item：6-1 |
| Details： |
| |
Test transformer is usually delivered together with a control panel for separate portable high voltage test.
◇Control Panel
Usage:
YD series frequency voltage test equipment is the strictest, most direct and most effective method for identifying insulation strength of electric apparatus. It can check out those mass defects which are very dangerous.
Features:
-Supervising function: can supervise output current, instrument voltage, zero indication, power indication, working indication, timing indication, etc.
- Protection function: over-current protection
- New pattern time relay, wider timing range
- New pattern current relay, more accurate and reliable
- Compact structure and light
Specifications:
-Input voltage: 220V±10% 50Hz
- Output voltage: 0～250（430）V
- Output capacity: 0～5kVA
- Timing range: 1S～99H
- Ambient temperature: -20ºC~50ºC
◇Test transformer
Description:
Test transformer is also called step-up transformer, for insulation strength testing on various kind of electric apparatus, elements and insulation materials, checking their insulation level and over-voltage capability.
