Frequently Asked Questions
What does ANSI compliance mean for an oil-immersed transformer?
It means the transformer is designed and tested to the ANSI/IEEE C57 series standards, matching the 60 Hz, North American style requirements of the destination market.
Is this transformer suitable for 60 Hz systems?
Yes. The unit is engineered for 60 Hz operation with core flux, impedance and cooling matched to the 60 Hz design.
What accessories are typically supplied?
Typical accessories include bushings, pressure relief device, liquid level gauge, temperature indicator and tap changer, with the package agreed at order stage.
Which testing is performed before shipment?
Routine tests to the applicable ANSI/IEEE requirements are completed on every unit, with test reports provided.
Can the transformer be supplied with a specific bushing or accessory brand?
Accessory brands can be specified where required; the final selection is confirmed at order stage and stated on the nameplate documents.
