Choose by duty rather than by enclosure: isolation, electric-furnace service, Scott phase conversion and solar inverter service address different electrical requirements. Supply the load cycle and interface data; construction and overload capability are then reviewed for that duty. High-overload designs can also be reviewed. Send the full load cycle, peak magnitude and duration, ambient conditions and cooling requirements. Overload capability is agreed for the selected design; no continuous overload percentage is assumed for the whole range. [![Electrical Isolation Transformer](https://entogo.ca/_astro/isolation-transformer.DSeX7yhX_Z1TxHzw.webp) Special-Purpose Transformers ### Electrical Isolation Transformer Entogo supplies electrical isolation transformers with separate primary and secondary windings. Select voltage ratio, kVA, shielding, grounding and enclosure for the load; isolation duty and dry-type construction are distinct requirements.

Furnace type, secondary current, voltage range, impedance, tap operation and the complete heat cycle determine the design rather than plant demand alone.

Define the two output loads, 90° phase relationship, voltage ratio and operating cycle before selecting the winding design.

Match the inverter/PCS voltage, winding arrangement, grounding, harmonics and thermal duty to the collector network and connection study.

The right pick turns on installation location, fire and code rules, voltage class, efficiency, and maintenance - not on which type is generally better.

This guide explains the 519-2022 voltage and current limits and how to specify mitigation before it becomes a field problem.

Here is how the pieces fit.
