Question

What is meaning of insulation class b/h of generator?

Answer 1

Answer:

Explanation:

The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification. The different classes are defined by NEMA,[1] Underwriters Laboratories (UL),[2] and IEC standards.

For complete electrically operated appliances, the "insulation system" is the overall design of electrical insulation of the energized components to ensure correct function of the device and protection of the user from electric shock.
