#177271 - (Simple) Isolation transformer |
For a PC based data acquistion system I need an isolation transformer to derive 230V ac from 415V ac. But in this project due to various reasons I just have access to a manufacturer who is just a regular transformer supplier. SO if I specify the following will I get an isolation transformer ?
1. The Primary and secondary windings must not be wound on top of each other. They should be on each leg of a E-core or U-Core. 2. The primary and secondary must have its own shield - which is just a thin sheet of copper encompassing the winding and brought out electrically. Of course he will do the other neccessary calculations for the no. of turns / wire size etc based on the load I specify. Apart from above what else is special to an isolation transformer when compared to a normal step down transformer ? Maybe higher insulation materials ?? Thanks. Raghu |
