FAQ

Frequently Asked Questions

How many days does an MV cell replacement take?

A single cell swap takes 1-2 days; a full panel set replacement up to a week. To minimize plant downtime we plan weekend/night shutdowns.

Is periodic maintenance for MV cells mandatory?

Yes. Regulations require maintenance at least once a year, with a comprehensive overhaul every 5 years. Otherwise your facility insurance is at risk.

What is needed to set up a new MV transformer substation?

A retail-supply contract, load demand letter, MV project approval, switchyard structure and grounding project — followed by equipment supply and commissioning. We handle it end-to-end.
