Bharat Heavy Electricals (BHEL) has manufactured and tested (short circuit) India’s highest rating auto transformer at the National High Power Test Laboratory (NHPTL) at Bina in Madhya Pradesh.
This is a new benchmark in the global transformer industry. Short circuit test is the most stringent, special type test for power transformers which is conducted to prove adequacy for power transformers to withstand abnormal conditions of short circuit to ensure reliability during their operations in the field.
This is BHEL’s 21 400 kV class transformer, which has passed the short circuit test, indicating the company’s prowess in the sector. The 500 MVA 400/220/33 kV auto transformer has been designed and manufactured at the company’s Bhopal plant for the Uttar Pradesh Power Transmission Corporation.
These high rating transformers play a crucial role in bulk power transmission to load centres and bigger cities.
