Transformer repair & rewinding
Rewinding and repair of all kinds of transformers, whoever made them.
01What we see most
Sound familiar?
- Burnt or shorted winding
- A smell of burning, visible charring, or the unit tripping its protection as soon as it is energised.
- Low or unstable output
- Output voltage sitting below where it should, or wandering under load.
- Overheating
- Running far hotter than usual, or oil temperature climbing where it did not before.
- Noise
- A hum that has changed in character, or rattling from the core.
02About the work
What to expect.
We rewind and repair all kinds of transformers, regardless of who built them. A transformer that has failed is usually worth repairing rather than replacing, and the same workshop that manufactures our own units does the repair work.
Bring the unit to whichever outlet is nearest you, or call and describe the fault first if you are not sure it is worth moving.
We do not promise a turnaround time before seeing the unit. Ask us when you bring it in and we will tell you honestly.
03Process
How it works.
Describe the fault
Call, message or send photos before moving a heavy unit.
We inspect
The unit comes to the workshop and we find what actually failed.
We quote the repair
You decide before any work starts.
Rewind and reassemble
Then testing, then hand-over.
—Case study
All our work“I send them anything with a winding in it. What I value is the report that comes back — what failed, why, and what they changed — so I can tell my client straight.”

A lightning-struck 100 kVA, back on the pole
An oil-cooled distribution transformer took a strike in a spring storm. We stripped, rewound and tested it rather than scrapping the tank.

Winter voltage up here is a lottery. The transformer they built for our kitchen and laundry load has not missed a beat through two seasons of snow.

05Questions
Asked often.
How does transformer repair & rewinding work at Paramount Electricals?
1. Describe the fault — Call, message or send photos before moving a heavy unit. 2. We inspect — The unit comes to the workshop and we find what actually failed. 3. We quote the repair — You decide before any work starts. 4. Rewind and reassemble — Then testing, then hand-over.
What do you need to know to quote for transformer repair & rewinding?
Rating in kVA and the make, if you know it. What it is doing — or not doing. When it started, and what changed around then. Which outlet is nearest you. With these, we can usually quote without seeing the unit.
What faults do you see most?
Burnt or shorted winding — A smell of burning, visible charring, or the unit tripping its protection as soon as it is energised. Low or unstable output — Output voltage sitting below where it should, or wandering under load. Overheating — Running far hotter than usual, or oil temperature climbing where it did not before. Noise — A hum that has changed in character, or rattling from the core.
How long will it take?
We do not promise a turnaround time before seeing the unit. Ask us when you bring it in and we will tell you honestly.
Do you repair transformers and motors you did not make?
Yes. Rewinding and repair of all kinds of transformers and motors is core work for us, whoever the original maker was.
Where are you located?
We have outlets at Maisuma Bazar in Srinagar, at Jalalabad, Sujwan in Jammu, and in Leh, plus our own factory at Sathu Payeen, Barbar Shah in Srinagar.
