GSES24D with optional extended frequency range (wideband transformer)
Meer informatieIf there are higher frequencies than the mains frequency, inductive voltage transformers always indicate resonances within a few kHz in the transmission path. The position of the resonance
point shifts downwards with increasing rated voltage. The measuring accuracy of harmonics and interharmonics with the aid of an inductive measuring transformer in relation to the voltage
quality in medium voltage networks is therefore limited.
The GSES12D/24D with optional extended frequency range is optimised for future standards and measurements up to 9 kHz, i. e. no resonances occur up to this frequency. A proven transformer principle is applied. This single-pole voltage transformer is used in 20 kV medium voltage networks. In addition to permanent monitoring of PQ requirements at grid transition points (EN 50160), the use for permanent monitoring of non-linear equipment is also conceivable.
