: Defines requirements for dielectric strength to withstand high-voltage environments. Thermal Performance

Instrument transformers are devices used to transform high-voltage and high-current electrical signals to lower levels, making them suitable for measurement, protection, and control applications. They are essential components in electrical power systems, providing isolation and scaling of electrical signals to ensure safe and accurate operation of instruments and equipment. iec 618691 pdf hot
