About Three Phase Distribution Transformers Up to 2.5 MVA as per IS 1180

The supplied Three Phase Distribution Transformers Up to 2.5 MVA as per IS 1180 is offered by us for use in the various applications as it is the backbone of electrical power distribution whether Delta or Star connected windings. The Three-phase, also written as 3-phase or 3 supplies are used for electrical power generation, transmission, and distribution, as well as for all industrial uses. Three-phase supplies have many electrical advantages over single-phase power. The Three Phase Distribution Transformers Up to 2.5 MVA as per IS 1180 are very effective and made for long term use.

Robust Construction and Protection

Each transformer is constructed using CRGO laminated cores, super enamelled copper or aluminium windings, and protected by multiple safety features. Buchholz relays, oil temperature/level indicators, and pressure relief devices actively monitor and secure operation during faults, ensuring the longevity and safety of the device in demanding outdoor environments.

Flexible Installation and Operation

Designed for versatile mounting, these transformers can be installed on poles or platforms, adapting to urban, suburban, or rural deployment. The Off Circuit Tap Changer is standard for adjusting voltage as needed during maintenance, with On Load Tap Changer options for continuous operation available on request.

High Efficiency and Compliance

Engineered to meet IS 1180 norms, these transformers demonstrate high efficiency-up to 99.5%. They deliver stable power output with minimal losses, noise levels within permissible limits, and reliable performance even under short-circuit conditions, verified through type tests. Anti-corrosive paint and an outdoor enclosure extend service life, making them ideal for varied climates.

FAQ's of Three Phase Distribution Transformers Up to 2.5 MVA as per IS 1180:

Q: How do Off Circuit Tap Changers (OCTC) work in these distribution transformers?

A: Off Circuit Tap Changers allow adjustment of transformer output voltage by manually changing tap positions when the transformer is de-energized. This helps maintain proper voltage regulation during maintenance or load changes without compromising efficiency or safety.

Q: What is the typical impedance value for these transformers, and why is it important?

A: These transformers generally have an impedance of 4% or 5% as specified by IS 1180. This value is crucial for controlling fault currents, ensuring system protection, and supporting proper coordination in multi-transformer networks.

Q: When should an On Load Tap Changer (OLTC) be requested instead of the standard OCTC?

A: On Load Tap Changers are ideal when frequent voltage adjustments are needed during operation without interrupting supply. OLTC should be requested for applications with variable load conditions where continuous voltage regulation is critical.

Q: Where can these transformers be installed, and how is the mounting type selected?

A: Installation can be on utility poles or dedicated platforms, as determined by site requirements and transformer size. Pole mounting is preferred for compact units and limited spaces, while platform mounting is optimal for larger capacities and easy accessibility.

Q: What protection devices are included in these transformers, and how do they enhance safety?

A: Standard protection includes HT/LT bushings, Buchholz relay, pressure relief device, and oil level/temperature indicators. These devices collectively monitor operating conditions, detect faults, and prevent transformer damage during abnormal events.

Q: How does the use of CRGO laminated core and super enamelled windings benefit transformer performance?

A: CRGO laminated cores reduce core losses and enhance magnetic flux efficiency, while high-grade super enamelled copper or aluminium windings ensure efficient current conduction, improved thermal management, and longer transformer lifespan.

Q: What makes these transformers suitable for export, import, and use across India?

A: Designed per IS 1180 standards, these transformers offer robust quality, high efficiency, and compatibility with varied Indian grid voltages (11/0.433 kV, 22/0.433 kV, 33/0.433 kV), making them ideal for exporters, importers, manufacturers, and suppliers nationwide.
