In general, current transformers compared to voltage transformers exhibit good frequency transmission characteristics up to 9 kHz. However, inductive components of load, cable resistance and various core materials can also adversely affect the transducer transmission characteristics for harmonic currents.
The GSWS24 with optional extended frequency range is optimised for future standards and measurements up to 9 kHz. Up to this frequency a class accuracy of <3 % is assured. A proven transformer principle is applied. This support current transformer is used in 20 kV medium voltage networks. In addition to permanent monitoring of electro-energetic quality parameters (e.g. harmonics limit values, THD) at grid transition points (EN 50160), for permanent monitoring the use of non-linear operating devices is also conceivable.
Wideband transformers, however, can also be used in conjunction with electrical energy meters, which can detect actual output beyond 50 Hz.
