Distribution transformers are an essential part of the power distribution system, converting high-voltage electricity from the transmission grid to the lower voltage levels required for use in homes, businesses, and other establishments. These transformers are typically located at various points along the distribution system to ensure that the voltage is maintained at safe levels and that the electricity can be distributed efficiently.
Distribution transformers provided by Jaybee Industries are available in 3 Phase / Single Phase ranging from 5 KVA to 2500 KVA up to 66 KV class with off-load & on-load Tap changer with or without Automatic Voltage Regulator (AVR) & Remote Controlled Tap changing Panel. The cooling method used in these transformers can be either oil-immersed or dry-type. Oil-immersed transformers use oil as a cooling medium to dissipate heat generated during operation, while dry-type transformers use air as a cooling medium.
Overall, distribution transformers are an essential component of the power distribution system, ensuring that electricity is delivered safely and efficiently to homes and businesses. With proper design, maintenance, and operation, these transformers can provide reliable service for many years, helping to power the modern world.
Pre-commissioning tests
Based on IS 2026, Jaybee Industries transformers are subjected to several tests before commissioning with no compromise on raw material quality and ensuring the healthiness of the transformer prior to its energisation.
Lightning Impulse Voltage test
The purpose of the impulse voltage test is to detect whether the transformer insulation withstands the lightning overvoltage which may occur in service.
Air pressure test
The air pressure test is performed to determine the total pressure of all gases dissolved in oil and detect whether the transformer is completely sealed and the transformer body is strong enough to withstand the pressure.
Temperature rise tests
The temperature rise test of a transformer is important to determine whether the temperature limit of the winding and oil is as specified by the manufacturer.

How do I choose a distribution transformer?
To choose a distribution transformer, consider factors like capacity, voltage rating, efficiency, and application requirements. Evaluate the load profile, environmental conditions, and reliability needs. Consult with experts and prioritize safety standards to ensure optimal performance and longevity for your specific electrical distribution system.
What are the types of distribution transformer?
The main types of distribution transformers include pole-mounted transformers, pad-mounted transformers, and underground vault transformers. Each type serves specific needs in electrical distribution, offering versatility and adaptability to various settings and applications within the power distribution network.
What is distribution transformer used for?
Distribution transformers are used to change electrical voltage levels for efficient power distribution. They step down high voltage from the power grid to lower levels suitable for homes, businesses, and industries, ensuring safe and reliable electricity supply in local distribution networks.
What is three phase distribution transformer?
A three-phase distribution transformer is a type of transformer designed to handle three-phase electrical power. It efficiently converts high-voltage three-phase electricity from the grid to lower-voltage three-phase levels for use in industrial, commercial, and residential applications, facilitating balanced power distribution.
What is the working principle of distribution transformer?
The distribution transformer operates on the principle of electromagnetic induction. When an alternating current flows through the primary coil, it induces a changing magnetic field, which, in turn, induces a voltage in the secondary coil, facilitating the transformation of voltage levels for power distribution.
