Three phase 200 kVA isolation transformers is 50/60Hz rated, dry type air self cooling of cooling method, step up/down voltages between 240 Volt and 480 Volt. The biggest advantage that isolation transformers offer is improved safety. Another advantage of isolation transformers is that they reduce power surges.
Generally, isolation transformers with power above 150KVA will be equipped with an alarm, which is used to detect the temperature of the transformer. When the temperature of the transformer rises to 150 degrees, the alarm will be triggered. At this time, the transformer needs to be manually suspended or stopped. Wait until the transformer temperature returns to normal, then continue to use.

Tips: Additional notes about installation of isolation transformer:
- The secondary ends of the transformer to be grounded is forbidden;
- People is prohibited to touch the transformer's terminals at the same time, otherwise, electric shock could occur.
- Users usually ignore the importance of the grounding of isolation transformer. It reduces the effect of transformer because of the bad isolation measures.
- Isolation transformer has the function of harmonic filtration, however, if the requirement beyond the supply, it is best to add a filter.
