What is BS EN 50708‑3‑1 about? 

BS EN 50708‑3‑1 discusses the large power transformer which defines the performance requirements of Large Power Transformers.

BS EN 50708‑3‑1 contains particular requirements for specific transformers or transformer applications, which are based on the requirements.

Note: BS EN 50708‑3‑1 cover the transformers under commission regulation which gives additional specific guidance for single-phase transformers, autotransformers, multi winding transformers and for transformers with OD and OF cooling systems, necessary for the correct application of energy efficiency requirements to these categories of transformers.

Who is BS EN 50708‑3‑1 for?

BS EN 50708‑3‑1 on general requirements for large power transformer is useful for:

Manufacturers of power transformers
Suppliers and distributors of power transformers components
Companies dealing with large power transformers

Why should you use BS EN 50708‑3‑1?

A power transformer means a static piece of apparatus with two or more windings which by electromagnetic induction, transforms a system of alternating voltage and current into other systems of alternating voltage which usually differs from the values at the same frequency for the transmitting purpose.

A large Power Transformer (LPT) is a large custom-built piece of equipment that is a critical component of the bulk transmission grid.

BS EN 50708‑3‑1 helps you ensure optimization of transformer losses, peak efficiency with the formulae and requirements specified in it.

BS EN 50708‑3‑1 provides you guidance on all the required accessories and fittings for a large power transformer, which will help you in manufacturing the power transformer insecure manner.

What’s changed since the last update?
