4000A High Current Generator
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 ground impedance testing easy and convenient.
2. Multi-point different frequency testing - Incorporating advanced international multi-point different frequency testing methods, overcoming the limitations of the two-point different frequency interpolation method, can clearly identify and eliminate bad measurement values caused by same-frequency harmonic interference, making measurement results more consistent with actual values.
3. Easy installation 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 installation 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. User-friendly interface - Using "one-key shuttle" (rotary mouse) technology and a large-screen graphical LCD, with full Chinese prompts, 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 for voltage and current are automatically converted based on the magnitude of the measured value, requiring no manual operation and being easy to use.
Product Overview:
It is a specialized equipment designed and manufactured specifically for electrical equipment testing in power departments and industrial and mining enterprises, such as current load tests and temperature rise tests on various switches, current transformers, and other electrical equipment.
This product has the characteristics of small size, light weight, integrated structure, stepless adjustment of output current, balanced current rise, wide load variation range, use of 0.5-class current transformers, digital display, beautiful appearance, reliable operation, simple operation, and safety. It is an ideal equipment for current rise tests 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 indicator light will be on, press the start button, and the green indicator light will be on. Connect the output terminal to the test object, and the current generator will wait 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, cut off the working power, and then remove the test wiring to ensure safety.
