Characteristics control


A) Ohmic resistance tolerance applied > -/+ 5% on value of nominal resistance 20° C
Sec. IEC 317-13(1) -/+ 3/5 % accordabile.

B) Dielectric strenght with voltage applied about CEI 34 : 2 x Volt ( <1500 ) *120% for 1 second.
Corrent applied:
- 2 mmA x < 0.3 Kw
- 4-8 mmA x < 0.3 Kw
Regulation applied CEI 34 -2-3 pag. 25 point 1.2

C) Inductance is applied with a value of delta from 2 to 10%

D) Surge test usually is applied 1.800 Volt for 2 seconds, but in case there should be any particular requirements we can make a different agreements.

E) Control sense of rotation. May be applied also on three-phase windings (exit 3 cables).

F) Visual control of cables, headers, insulating of closure, dimensional of lenght of cables and terminals.
