Top-oil thermal model for power transformers that reflects ambient temperature profile in Malaysia

The International Electrotechnical Commission (IEC) has created standards for transformers, which are normally adhered to by the great majority of those that are used in locations all over the world. When it comes to calculating transformer ratings, Malaysia is one of the nations that use the Intern...
