Secondary circuit test accuracy 0.00mA-10A: ±1%±5dgt (three-channel being displayed in one screen) (23C±3C less than 70%RH)
CT ratio Three kinds of transformation ratio indications :
(1)convert the transformation ratio based on the adjustable basic value of 5A for secondary circuit current; (2)convert the transformation ratio based on 10kV-YY of 10kV/380V, that means 1st means the current of the line under 380V, 2nd means the secondary circuit current of CT under the 380V, and then calculate the ratio between the 10KV line and the secondary circuit;
(3)the measured current ratio can be calculated by the measured CT ratio between the primary and secondary circuit)
ReferenceRange Reference range of transformation: 0.00A ~ 99.99A, the default secondary circuit current is transformed to 5A;
Range of Ratioerror
(F.Er) 0.0% ~ 9.9%, the error between the measured CT ratio and the preset CT ratio
Range of CTratio 0000-9999/0.0A-9.9A
ETCR9500C tester is widely applicable to the current detection, abstracting-proof of electricity and field operations of transformer substations, power plants, electrical power inspection departments, industrial and mining enterprises, inspection station, and electrical maintenance departments.
Current clamp: it adopts the special alloy, the latest CT technology, and the double shielding technology for a high accuracy, stability, and reliability during continuous monitoring in the entire year.
Principal machine: it displays four sets of current signals, CT ratio, phase angle difference , and polarity visually in one screen simultaneously, which memory can store 1,500 sets of data; it is available to set the auto-save interval time to monitor leaker.
HV detector breaks the traditional structure with an automatic opening and closing functions, it is easy to clamp or release measured wire by pressing or pulling back insulating rods, with the advantages of safety and time-saving.
Monitoring Software: Functions such as real-time monitoring, historical data search, accessing, browsing, saving, and printing data available; dynamic display;
