Tesla Transformers (Global) Private Limited is one of the few/first units manufacturing energy efficient transformer 25 KVA to 2500 KVA in India. We had supplied more than 15000 units of various rating energy efficient transformers to electrical utilities in India.
Energy efficient transformers are rated as star 1 , star 2 or above star rating (As Per IS : 1180, Part-1). In energy efficient transformers we guarantee individually the no-load loss and load loss without ant positive tolerance at 50% and 100% load condition (at rated voltage and frequency and at 75*c).
The maximum allowable losses at rated voltage and rated frequency permitted at 75*c for distribution transformers can be chosen from the values of star 1, star 2 rating for transformers. No positive tolerance shall be allowed on the maximum losses displayed on the label for both 50% and 100% loading values.
