Transducers AC/AC - current-voltage transducers

Current-voltage transducers AC/AC

Current-voltage transducers transform primary alternating curent to secondary alternating voltage withe accuracy class 0.5 or 1. They are designed for supplying measuring and protective circuits of electrical power devices.

Transducers conform with PN-EN 60044-1 standards (without transducers IU type):
- with accuracy class 0.5 and 1 in range from 5% to 120% rated primary current
- with accuracy class 3 in range from 50% to 120% rated primary current

Transducers current-voltage EULA 0 type with primary current 5 A or 1 A can be used in secondary circiut of current transformers changing current signal on voltage signal.

Advantage of our transducers is rated short-time thermal current (1 sec): I_th = 60 * I_pn.

Secondary circuit of current-voltage transducers can be open or shorted.
Also can be loaded the larger resistance than passes in technical data.

Technical data:

Rated secondary voltage		U_sn= 1 V; 2 V; 5 V; 10 V; 15 V
Primary current		I_pn= 1 ÷ 3000 A
Permanent overload		I_pn= ext. 120%
Rated burden		S_2n = 5 ÷ 75 kW
Accuracy class		0.5; 1; 3
Rated short-time thermal current 1 sec. r.m.s.		I_th = 60 * I_pn
Rated dynamic current (for transducers with primary winding and cable type)l		I_dyn = 2.5 * I_th
Rated dynamic current (for bus bar type transducers)		depends on circuit (practically unlimited)
Frequency		f = 50 ÷ 60 Hz
Max. voltage		U_m = 0.72 kV or 1.2 kV
Test voltage		U_p = 3 kV or 6 kV
