Structure overview:
The control cabinet is of GGD closed structure and opposed access door at the front and back for operation and maintenance. The gauge, control switch and potentiometer are installed front door plank of the cabinet; the signal light is installed on the top panel in the front of the cabinet and the entrance hole is set at the bottom of the cabinet for user connection. See Figure (II) for its appearance and installation dimensions.

Part three of Large-current Sensor Series
IV Performance Index
1.The standard ranges of our present products are:6KA,10KA,15KA,20KA,25KA
,35KA,50KA,65KA,75KA,100KA,125KA,150KA,180KA,240KA,320KA,360K A,420KA,500KA,600KA.(We could make according to user’s needs for other range between 1 and 600KA)
2.Output pressure:DC 0~5V or 4~20mA(If user needs more for output signal,
please make it clear on contract)
3.Accuracy:
0.5%(magnitude×0.5%+end scale value×0.2%)
0.2%( magnitude×0.2%+end scale value×0.1%)
0.1%( magnitude×0.1%+end scale value×0.05%)
4.Other influential factors on magnitude error(accuracy is 0.1%)
(1) Position effect: When sensor’s eccentricity size is 1/3 of the distance between busbar and the edge of window, its position additional error is no more than 0.05%.
(2) Repeat error of load and upload is less than 0.05%.
(3) Stray field effect:When stray magnetic field on the spot is no more than 200 gauss, the effect that the stray magnetic field has on the accuracy of sensor is no more than 0.05%.
(4) Additional error of temperature: additional error of sensor is no more than
0.05%/10℃.
5. Power waste is less than 5W.
6. Insulation resistance: on the condition of environment temperature of 15℃~35
℃ and relative humidity of 45%~75%,the insulation resistance that sensor power supply has on shell is more than 20MΩ.
7. Overloading capability: infinitely great.(the accuracy cannot be guaranteed if range is exceeded, but the sensor would not damaged.)
8. Standard size is generally subject to size of inner frame, see Table 1(outer frame size=inner frame size +210mm,thickness is averagely 75mm)
