Electrical Properties
Based on model TZ1L
Output Voltage Properties Vo=15mV min ( at lo=25mA, R=1kΩ . f=60Hz )
Remanence Magnetism T=10% Max ( at IDC=50AT )

Thermal Properties tv = Max 10% ( at -10°C ~ +65°C )
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°C to +65°C at the ambient temperature
4) Hair-pin properties : At the balanced current equivalent to 6 times of the rated current along around 360
degree, V" is the maximum output voltage.
5) Pulse width properties : the wave width at Vo=10mV
