Test transformer

Test transformer Test transformer Test transformer
Product name:Test transformer
Item:6-1
Details:
 
◇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: -20℃~50℃ 

◇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.
