Electrical Properties

(Based on model TZ1L)

Output Voltage Properties Vo=15mV min ( at Io=25mA, R=1KΩ, f=60Hz ) Remanence Magnetism T=10% Max ( at IDC=50AT ) Thermal Properties tv = Max 10% ( at -10℃ ~ + 65℃ ) Hair-Pin Properties V" = 6mV max ( at IL=30A ) Pulse Width Properties Tp= 2.5m sec min ( at Vo = 15mV level )

1) Output voltage properties : Being measured after demagnetized 2) Remanence magnetism : Variation of the output voltage between the virgin CT's and the saturated CT's 3) Thermal properties : Variation of the output voltage from -10℃ to +65℃ at the ambient temperature 4) Hair-pin properties : At the balanced current equivalent to 6 times of the rated current along around 4) Hair-pin properties : 360 degree, V" is the maximum output voltage. 5) Pulse width properties : the wave width at Vo=10mV
