Wound-Primary Current Transformers for Indirect Measurement of Sinusoidal AC up to 100 A
As opposed to bushing-type current transformers, wound-primary current transformers have 4 screw terminals. Primary and secondary current are both connected by means of terminals. Wound-primary current transformers are suitable for low amperage current for which bushing-type current transformers cannot be used.
Thermal continuous current rating Icth: 100% IN
Thermal short-time current rating Ith: 60 x IN, 1 Sek.
Max. operating voltage Um: 0,72 kV
Insulation test voltage: 3 kV Ueff, 50 Hz, 1 Min.
Nominal frequency: fN: 50 Hz
Insulation class: E (120°C)
