A. adopt SCM control technique and achieve automatic
expiation intelligence of electric-net non-power.
B. Having two sorts of inspection system and make whole load range
C. Can resist 2000 voltage interferential pulse which inputted from
power supply directly.
D. Sample physical measure is non-power current which is commended
by national energy sources department.
E. Counter display can show electric net power-factor whether it
is over voltage value, and also can show all kinds of parameter
intuition strictly F. Have stochastic self-inspection function without
offering capacity of expiation capacitor of current transformer,
and can be seasoned with different parameter automatically.
G. Phase-order of sample signal can be differentiated and changeover
H. Conciseness man-machine conversation, operating, altitude simpleness
I. Control power: each group output contact capacity for 220V8A,
J. Devotion opening limiting: =1. 1double Ic=cos presetting
K. cutting opening limiting: =0.5double Ic, over press opening limiting:
L. Throwing and cutting time-delay: 10 second 100second adjustable,
output circuit way for 4, 6, 8, 10, 12 circle throwing chip. (JKL7C-N
type output circuit way for 2,3,4)
