Bhagyanagar Electricals - Services


We remain in a prime position to offer quality work and total customer satisfaction at affordable rates with the aid of following factors:

Well-trained field-staff who can execute all testing procedures and repairs. They can perform safe and quality workmanship on all transformers, junction cabinets, switch gear, enclosures, and substations

We also perform internal and external inspections and also paint units including substations, Breakers, OCBs, ACBS, VCBs and poles. We use primer and finish coats specially engineered for corrosion resistance and are weather proof

Other allied tasks comprises of laser testing, OHMS testing, and retrofitting locking mechanisms for units failing to meet standard norms laid down

Prevention of transformer replacement and extend cabinet life plus deterioration and reduces the risk of potential safety hazards

Guarantee all repaired products will be dispatched to the customer within 2 to 4 weeks on average

All our minor check and repair costs are less than 10% of the cost of new equipment, and rewind costs are typically economical

We dwell upon the importance of Field service work; it remains a cost-effective method for maintaining Pole mounted equipment that benefits electrical service providers, as well as their end users.

As on now, we possess 18 crews and 5 mobile repair units ready to serve your transformer maintenance needs. They remain ready to perform all field work around the clock and all over the state of AP.


A well-worked out and devised quality policy governs our testing norms. It is outlined as follows:

Every transformer we recondition or rewind is guaranteed for 12 months against defects in workmanship and materials. Following this, a test certificate is issued at the fine of handing over the equipment

In case any one of our units fails within 12 months from normal use, we'll repair it free of cost

Strict & tough quality control steps govern each and every step of the overhauling process. For instance, a reconditioned unit from BE receives extensive tests and replacement parts as needed. Likewise, a transformer requires a complete rewind, 100 percent copper is used

Oil in all transformers receives IFT, dielectric and PCB tests. With the help of 2 filtering systems and the Fuller's Earth process for removing acid from the oil, we guarantee minimums of 26 IFT and 30 KV dielectric strength

In addition to this, we also maintain an adequate quantity of transformer oil to meet our customer requirements. Prior to shipping transformers, we also perform the necessary tests:

Turn ratio on all Tap Connections

Polarity and Phase Relation

DC High Voltage test at 2 times rates line to line voltage plus 1,000 volts:


HV to LV


HV to Ground


LV to Ground

Core loss and excitation current at rates voltage

Load loss and impedance at rated voltage

Induced test at two- (2) times rates voltage at 100 hertz for 7,200 cycles

Our patrons can be assured that we exercise total high quality standards of each & every transformer and assure their on-time delivery. Where a technical problem arises, an immediate and satisfactory answer comes from our stables.
