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.
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.
We at Jaybee Industries, are manufacturing Transformers with Losses conforming to the Star Labelling Scheme as per the Bureau of Energy Efficiency ranging from Star 1 to Star 5 & as per Energy Efficiency Levels specified in the latest IS 1180 under time-to-time amendments ranging from EEL1 to EEL5. Our transformers bear the star label as shown in the figure.
Every Transformer dispatched carries our Routine Transformer Test Certificate which contains all the Technical Data such as Losses, Impedance, Ratio, Resistance, Insulation Level, Oil BDV, warranties etc.
We at Jaybee Industries are manufacturing transformers with the losses and impedance values as mandated for different Energy Efficiency Levels & kVAs.
Maximum Total Losses Upto 11 Kv Class Transformers (Clauses 220.127.116.11, 18.104.22.168, 22.214.171.124, 6.8.2 & 126.96.36.199)
