Automatic Potential Transformer Test Bench
Automatic potential transformer Test bench
ZCHG-12 Automatic potential transformer Test bench is for testing the voltage/current transformer error and impedance parameters and transformer power frequency withstand voltage, which is ideal equipment for power system and other departments’ test of transformer.
The integral device is composed of a mutual inductor calibration instrument, a load box, a speed mutual inductor calibration table, a speed transformer control console, and other parts. Through PC transformer error management software to set the mutual inductance type, range, accuracy class, secondary load, power factor, measured transformer and the main parameters, a rise process flow (3-5 minutes) can do the work for 12 current transformers’error correction inspections with the realization of the real speed checking function..
Ct test bench based on principle of newest virtual Instruments design, users just need operate the virtual interface by using the mouse and keyboard, input the transformer type, measurement range, precision class, capacity, power factor, can finish the transformer test, analyze, calculate and manage the test results, and print all kinds of records and certificates according users requirements. This is the ideal equipment for power system and others company who need test the transformers.

Automatic potential transformer Test bench Features
1. The device uses the programmed control technology for the fine adjustment, which makes the position of the test point more rapid and accurate.
2. The device in a plurality of current transformer measurement speed with the improvement of quality. In 3-5 minutes of time can do the measurement for any twelve transformation ratio of current.
3. The device can be used for the measurement of the rules and non regulation of transformer, users can specify the measurement of any percentage point.
4. With the functions of measurement, controlling, display by using single clip.
5. With PC interface, improve the office automation level, reduce the labor intensity.
6. With LCD, provide friendly operation interface and rich measurement information.
7. Can auto measure the transformer, auto switch the current, voltage load box.
8. Can inform the users the error information in time.
9. Reaching Standard Class 2
10. The transformation ratio of the standard instrument transformer and calibrated instrument transformer doesn't have to be equal. We can test directly once the rated primary voltage or current of the calibrated transformer is not bigger than that of the standard transformer. And it's easy to operate.
11. The device configuration of the 5A standard current transformer, the current load box configuration of the 5A load value 2.5A-60A, the voltage load box configuration of the 100V load value form the 1.25VA-158.75VA basically meet the user’s requirements. Load box can be automatically switched in the measurement.
