Current transformers and sensors

Our standard offer consists of current transformer PT4/Vi 1000 and PT4/H 1000, precise current transformer PPT4/Vi 1000, PPT4/H 1000, PPT3/Vi 500 and current sensors PS4/Vi 1000, PS4/H 1000, PS2/Vi 200 and PS1/Ve 100.

Current transformer of PT line, based on steel tape wound toroidal core, current transformers of PPT line, based on nanocrystalline tape wound toroidal core and current sensors of PS line, based on high permeability ferrite toroidal cores, are used for galvanic separated AC measurements.

The primary winding is usally set up of one put-through conducting wire, which leads through the inner transformer opening. The secondary winding is buld-in. With the change of primary winding put-through number, you can change the conversion ratio and its current range.

The specification of linearity, current range and conversion slope is valid, when the secondary winding is loaded with the recommended resistor. If the linearity isn't the primary demand, it is possible to change the value of resisor corresponding the demand and thereby to obtain needed conversion slope or maximum current.

Precise current transformer for precise mains current measurement up to tens Amps. Excellent linearity even with increased load (higer ratio slope).

Isolating voltage 2500 V and middle hole Ø 10 mm.

Very good technical data requires appropriate signal processing. The convertor example, designed especialy for these transformers, complies with these requirements. (Convertor is only an example and is not available for sale).
