Current transformer BD 12–72 kV

Current transformer BD 12–72 kV,
Medium voltage current transformers of the type BD are use in indoor switchgear.
in addition They transform high currents up to 4,000 A into standardized,
equivalent values for counters, measuring equipment and protection devices.
furthermore The support-type current transformer in a dry block design has been develope for use in air-insulated medium voltage cells.
A specific core padding and a complete casting of all active parts in epoxy resin ensures that the magnetic properties and therefore,
olso the class accuracy remain constant for decades.
Safe operation is guarantee thanks to compliance with the partial discharge limit values of IEC 61869-1.
The primary and secondary connections made of brass as standard,
while the protective cover on the secondary terminals is constructe from transparent polycarbonate.
Any installation position is usually possible. However, when using the 72 kV variant,
the installation position must discusse with the manufacturer to take account of any mechanical requirements (earthquakes, vibrations),
unless the device is installe upright.
Moreover, the current transformers are designe according to the applicable national and international standards.
It is normally possible to accommodate special customer requirements upon request.
