Relay Protection Tester
Automatic Capacitance And Inductance Tester With 3 In 1 Function
The ZX-CH automatic capacitance and inductance tester can measure a single capacitor in a group of parallel capacitors without disconnecting the wire, and can also measure the inductance of various reactors.
This type of capacitance and inductance tester can also measure the power frequency status The current is low, the wiring is convenient, the operation is simple, the workload of the maintenance personnel is reduced, the test efficiency on the spot is greatly improved, and the safety guarantee for the normal operation of the power grid is provided.
Features
1. The instrument can measure the single capacitance of a group of parallel capacitors without disconnecting the wire (both single-phase capacitance and three-phase capacitance can be measured). At the same time, the instrument can also measure the inductance of various reactors. The three-phase capacitance measurement is connected once according to the wiring diagram according to the connection method of the capacitor bank. The built-in automatic commutation wiring function of the instrument eliminates the cumbersome wiring commutation short circuit operation, and the result is automatically output after the test is completed.
2. During the measurement, the instrument can display the measured capacitance or inductance value, as well as the measured voltage, current, power, frequency, impedance, phase angle and other data, so as to better analyze the quality of the test sample;
3. The instrument adopts 8.0 inch 800 × 600 graphic dot matrix 65K color screen, touch operation, can be clearly observed during the day and night, Chinese menu prompt, easy to operate.
4. The instrument has a built-in large-capacity lithium battery, and the continuous working time is not less than 8 hours
5. The instrument has built-in large-capacity non-volatile memory: it can store 200 sets of measurement data.
6. The instrument is equipped with a U disk interface, which can store any set of measurement data (limited by the capacity of the U disk).
7. The instrument has a built-in high-precision real-time clock function: it can perform date and time calibration.
8. The instrument comes with a high-speed micro thermal printer: can print measurement and historical data.
9. Instrument test power supply overcurrent protection function: short circuit of power supply output will not damage the instrument.
