ELEQ Bushing Transformer for Medium Voltage Switchgears

Smart Grid developments require more measurements in Medium Voltage Switchgears (MV-SG). For example for energy management purposes or revenue metering (billing). In addition, the footprint of Medium Voltage Switchgears needs to be reduced. Hence, these additional measurements may not increase the size of Medium Voltage Switchgears. To meet those requirements ELEQ designed and produced a new Bushing Current Transformer which fits in the existing Medium Voltage Switchgears on a spot which was not used yet.

With one of our customers, who choose ELEQ to meet the market trends described above, we designed a new bushing transformer. Please find below a quote of our customer:

“We see ELEQ as one of the most innovative companies within the area of protection and measurement CTs, which provides us with up to date products, new products and competitive terms and conditions.”

This new bushing transformer, the SBM 106-54-82, is a low voltage current transformer for mounting around the bushing/conus connector in medium voltage switchgears. With this compact transformer additional measurements are possible without increasing the size of the medium voltage switchgear.

Advantages SBM Bushing Transformer

First of all, due to its optimized design the bushing transformer fits around almost all bushing connectors. The window size of the transformer bushing CT is 82 mm. Also the outer dimensions are optimized which makes it suitable to mount the transformer bushing CT between the phases in medium voltage switchgears with its size of 106 mm.

In addition, those compact dimensions decrease the Total Cost of Ownership (TCO). In addition the transformer bushing CT is executed with a click system which secures correct installation and reduces the Total Cost of Ownership.

Additional the bushing transformer is designed to measure accurate at low temperatures. With the new bushing transformer measurements are possible till -35°C.

Furthermore, because of the sealable connectors the bushing CT can be used for revenue metering (billing).

Also, the ELEQ quality assurance system is recognized, according conformity assessment procedure, by the National Metrology Institute of German (PTB). So the SBM current transformer can be used for billing purposes as soon as it is placed on the market. These current transformers can be supplied with a declaration of conformity. This enables ELEQ to declare and confirm that its products meet the basic requirements of the law on measurements and calibration.

In conclusion, if you are looking for more measurements without a footprint expansion for your Medium Voltage Switch-gears, meet our new Bushing Transformer which fits in the existing Medium Voltage Switchgears on a spot which was not used yet.
