200 kVA transformer: price, load and use
A 200 kVA transformer serves about 160 kW. It fits a mid-size factory or an apartment block with several lifts. Many buyers compare it with 250 kVA. The right answer depends on your demand today and how much you expect to add in the next few years.

Load it serves
At 0.8 power factor, a 200 kVA transformer delivers about 160 kW. We usually plan for 20–25% headroom so it doesn't run hot at peak and you have room to add machines.
Typical use
Mid-size factory, apartment block, commercial building.

Room and plinth space
A plinth-mounted unit needs a fenced enclosure or a ventilated room, space for the LT panel, a cable trench and safe working clearance. We measure your site and show the layout in the quote.
Approvals needed
- Utility application for the new or increased connection
- Substation design and drawing approval from the Office of the Chief Electric Inspector (OCEI)
- Inspection before the supply is switched on
- Building owner or landlord consent where the site is rented
Frequently asked questions
How much load does a 200 kVA transformer run?
About 160 kW at 0.8 power factor. In practice we keep 20–25% headroom, so plan for a steady demand a little below that.
Can I add more load later?
Yes, if you leave headroom now. If you expect to grow, compare the next size up. A transformer that is far too large still has fixed losses every month.
What approvals does a 200 kVA installation need?
Usually a utility application for the connection and substation approval from the Office of the Chief Electric Inspector (OCEI), followed by inspection before switch-on. We prepare and file the paperwork with you.
Is the price on your quote fixed?
Yes. Our written quote lists every line item with brands and specifications. It only changes if you change the scope.
