Sempra Electric Pvt. Ltd. designs and manufactures power transformers that step voltage up or down across generation, transmission and distribution networks.
We engineer each unit to minimize energy losses, extend service life, and maintain stable performance under heavy loads.
A power transformer transfers electrical energy between circuits at different voltage levels, without changing frequency.
Power transformers typically serve transmission networks and generating stations, operating at higher voltage ratings than distribution transformers.
It improves grid efficiency by reducing transmission losses over long distances.

Frequently Asked Questions

Q1: What does a power transformer manufacturer do?
A1: It designs, builds, tests and supplies transformers that raise or lower voltage in power transmission and large-scale distribution systems.

Q2: Where are power transformers used?
A2: They are used in power stations, transmission substations, industrial plants and renewable energy projects.

Q3: How is a power transformer different from a distribution transformer?
A3: Power transformers handle higher voltages and capacities in transmission networks. Distribution transformers supply lower voltage to end users.

Q4: Does Sempra Electric offer customised power transformers?
A4: Yes. Specifications such as rating, voltage, cooling type, impedance and accessories can be tailored to project needs.

Q5: How do I choose the right power transformer?
A5: Consider load capacity (MVA), voltage ratio, efficiency, cooling method, installation environment and applicable standards.
