What is power transformer protection?

The power transformer protection is realized with two different kinds of devices, namely the devices that are measuring the electrical quantities affecting the transformer through instrument transformers and the devices that are indicating the status of the physical quantities at the transformer itself.

Do distribution systems need protection against overcurrent and overvoltage?

Distribution systems need protection against overcurrent and overvoltage. In this chapter, protection will be limited to overcurrent considerations only. With the introduction of computer‐based protection devices, the existing protection systems are changing gradually.

What accessories are available with a medium-voltage power & distribution transformer?

Medium-voltage power and distribution transformers are typically available with several types of accessories, including connections to primary and secondary equipment, temperature controllers and fan packages, integral fuses for transformers with padmount-style enclosures.
