Finding the power factor
Measurements on equipment with low power consumption
On a perfect electrical network, the voltage and current signals are sinusoidal. As a result, the power factor is the same as the cosine φ (displacement power factor). In industry, there are usually machines or other electrical equipment generating reactive power which adversely affects the power factor.

Flicker
Electrical network quality and human health
Flicker (term used by the IEC/EN standard) refers to variations in brightness due to small voltage fluctuations. These fluctuations are caused by the operation of various types of equipment connected to the network, such as arc furnaces, welding machines, motors, etc.
