EUB Current and voltage transformers

EUB Current and voltage transformers

A wide spectrum of current and voltage transformers are used for various requirements in electrical power engineering. The experiments include a practical hands-on investigation of transfer response, over-current factor, absolute and phase angle error, as, for example, under varying loads. In addition to this, standard operation requirements, short-circuit and asymmetrical faults can also be explored.

The protection of system facilities and components is not only dependent on selective protection equipment but also on the detection and measurement of the lowest fault currents and voltages. Various types of measurement circuits have to be used for different star-point circuit configurations in order to correctly detect and localise potential fault types.
