FAQ
Frequently Asked Questions
A voltage transformer is built for measurement accuracy (metering and protection), while a control transformer is built for duty — supplying control, indication and auxiliary circuits reliably rather than measuring voltage precisely.
Metering-grade LT voltage transformers are available in accuracy class 0.2, 0.5 or 1, depending on the application.
Yes — secondary voltage and burden are commonly matched to a specific panel or control-circuit requirement; contact our engineering team with your specification.
Dry-type construction, either epoxy or varnish-impregnated windings, avoiding the maintenance requirements of oil-filled units.
Dry-type construction means minimal routine maintenance under normal conditions. Periodic visual inspection and insulation resistance testing are still good practice as part of a panel's general maintenance schedule.
