VPI and cast resin are two dominant technical routes of dry-type transformers,differentiated greatly in manufacturing craft,coil structure,performance,cost and applicable working conditions. Cast resin dry transformer ado...

What is cast resin dry type transformer?

Cast resin dry type transformer is the most mainstream branch of dry-type power transformers, whose high and low voltage windings are fully sealed and encapsulated by epoxy resin under vacuum casting technology. Differing...

What is a dry-type transformer and how does it work?

A dry-type transformer is an oil-free static power transformation device whose iron core and winding coils adopt solid insulation+air as coolingdielectric medium instead of mineral insulating oil used in conventional oil-...

How to Solve Transformer Voltage Instability

Voltage instability of a transformer is usually manifested as the output voltage being too high, too low, or fluctuating frequently. It will affect the normal operation of electrical equipment and even cause equipment dam...

How to Judge Burned Transformer Windings

It is crucial to accurately judge whether the transformer windings are burned for equipment maintenance and fault troubleshooting. The judgment can be carried out through visual inspection, smell identification, resistanc...

Causes of High No-Load Power Consumption of Transformers

The no-load power consumption of a transformer (also known as no-load loss) refers to the power consumed by the transformer when it is connected to the power supply side, the secondary side is open-circuited, and it is in...
