Product Details

Main Features:

1. Strong anti-interference capability  Adopting advanced digital frequency-selective measurement technology, with sharp frequency selection characteristics and a passband of only ±0.5HZ, effectively shielding interference signals. The anti-interference capability and test speed are superior to similar imported products, making grounding impedance testing easy and simple.

2. Multi-point different frequency testing   Drawing on advanced international multi-point different frequency testing methods, it overcomes the limitations of the dual-point different frequency interpolation method, can clearly identify and eliminate bad measurement values caused by same-frequency harmonic interference, and the measurement results are more consistent with actual values.

3. Simple laying of auxiliary measurement electrodes   Due to the use of digital frequency-selective measurement technology with strong anti-interference capability, the test circuit does not require high current testing, the voltage measurement input impedance is high, and the laying of auxiliary current and voltage electrodes is convenient, significantly reducing work intensity and improving work efficiency.

4. Simultaneous display of multiple test parameters on the same screen   Simply select the frequency to be tested, and the voltage, current, impedance, resistance, reactance, power factor angle Φ, inductive + (L), capacitive - (C) at the selected frequency, as well as multiple measurement results and their arithmetic mean, are displayed on the same screen at a glance.

5. Easy operation and friendly interface   Using "one-key jog" (rotary mouse) technology and a large-screen graphic LCD, with full Chinese prompts, it is convenient and intuitive.

6. Automatic calculation of average impedance   Each measurement result can be selectively saved, and the saved data is displayed in the data area of the screen. The instrument automatically calculates the arithmetic mean of multiple saved measurement data and displays it, saving manual calculation and being convenient and practical.

7. Automatic range conversion    The measurement ranges of voltage and current are automatically converted according to the magnitude of the measured value, requiring no manual operation and being convenient to use.

 Product Overview:

It is specially designed and manufactured for electrical equipment testing in power departments and industrial and mining enterprises, such as current load testing and temperature rise testing of various switches, current transformers, and other electrical equipment.

This product is small in size, light in weight, adopts an integrated structure, has stepless output current adjustment, balanced current rise, wide load variation range, uses 0.5-class current transformers, digital display, beautiful appearance, reliable operation, simple operation, and safety. It is an ideal equipment for current rise testing in industrial and mining enterprises.

Working Principle:

1. Must have good grounding.

2. After connecting the working power supply, turn on the switch, the red signal light lights up, press the start button, and the green signal light lights up. Connect the output terminal to the test object, and the current generator waits for current rise.

3. Rotate the voltage regulator evenly clockwise, and pay attention to the output current indicator on the operation panel until the required high current is reached.

4. During the test, once any abnormal phenomenon is found, the power should be cut off immediately, and the test should be carried out after finding out the cause.

5. After the test, the voltage regulator must be returned to zero, press the stop button to cut off the power, and cut off the working power before removing the test wiring to ensure safety.
