LV Current and voltage transformers

        Low voltage CT’s are single-phase low power transformers working under conditions similar to short circuit and converting the current flowing in the primary winding into secondary winding current meeting certain accuracy norms. The devices are inside plastic enclosements made of slow-burning, shock resistant material.

We have a wide range of different ratio, power and accuracy class transformers in our offer. There are following types available:

-ELA series transformers - available in version with primary winding or with round aperture for different sizes of cables.
-ISN series transformers - mounted directly onto current circuit busbars.
-IMW, IMP and IMS series transformers - available in following versions (depending on the type): with primary winding, with round aperture or busbar mounted.



MV current and voltage transformers

We offer both current and voltage transformers in our MV range. They can be used to feed measuring equipment, as well as protection circuits in electric energy appliances with nominal voltage of up to 24kV and frequency of 50Hz.

MV transformers are low-power voltage transformers working in state similar to idle and converting high primary voltage into lowered secondary voltage meeting the requirements of their accuracy class. Transformers can work at heights up to 1000m above sea level, in internal appliances, in the temperature range from -10 to +50˚C, in humidity of 90%.

We also offer UMZ type of MV transformers with one or two insulated terminals, available in a variety of verions with different nominal primary voltage, secondary voltage and accuracy class.



MV current transformers

SN, ASK and IMZ type current transformers are manufactured in resin insulation and can be used to feed measuring equipment and protection circuits in electric energy appliances with the highest permittable voltage of 24kV and the frequency of 50Hz. The SN, ASK and IMZ CT‘s are single-phase, low-power transformers working under conditions similar to short circuit and converting primary current flowing in the high-potential circuit into low-potential secondary current meeting the requirements of the accuracy class.
