Increased use of power electronics increases the amount of disturbances and harmonics in the distribution networks. High quality on the power supplies getting more and more important for both users and utilities.
Harmonics and disturbances can be limited by different types of filters where the filter resistor is an important component.
One of the key factors for the filter resistor is low inductance. Resistor element type Expanded Mesh offers both low inductance as well as excellent heat dissipation. Cressall filter resistors are used in applications like
