Low-voltage grids are used to supply electricity to consumers at the lowest voltages. Zelisko’s low-voltage current and voltage transformers focus primarily on energy metering applications.
Our high-precision instrument transformers are tested and supplied in compliance with the relevant national energy metering standards (PTB; BEV; ESV; GOST). All our transformers have a completely maintenance-free, dry-type design, and no recalibration is required at any point in the product life cycle.
Slip-On Current Transformer
Slip-On Current Transformers are suitable for both measuring and protection purposes. Each size allows a large number of variations in height and inner diameter due to the modular design of the casting molds.Inquiry
A fully enclosed dry-type voltage converter with class E insulation for use in low-voltage switchgear. The primary and secondary windings are arranged around a coil body and are covered by two halves of the housing made of self-extinguishing material. The converters are manufactured according to IEC 61869-3 standards.Inquiry
Ring Core Current Transformer
Ring Core Current Transformers are suitable for both measurement and protection purposes. Each size allows a large number of variations in height and inner diameter due to the modular design of the potting molds. This means that multi-core converters, e.g. measuring and protection cores, can also be offered in one device without any problems.Inquiry
