2020-07-21
The MC6000B dielectric loss tester breaks away from traditional bridge measurement methods by employing variable-frequency power supply technology. It utilizes a microcontroller and modern electronic techniques to achieve automatic frequency conversion, analog-to-digital conversion, and data processing, resulting in strong anti-interference capability, rapid testing speed, high accuracy, fully automated digital operation, and simple handling. The power supply features a high-power switching power supply that outputs pure 45 Hz and 55 Hz sine waves with automatic voltage boosting, capable of delivering up to 10 kV. It also automatically filters out 50 Hz interference, making it suitable for on-site testing in environments with severe electromagnetic interference, such as substations. This instrument is widely used in the power industry for dielectric loss measurements of equipment including transformers, current and voltage transformers, bushings, capacitors, and surge arresters.

The MC6000B is widely used in the power industry for dielectric loss measurements of equipment including transformers, current and voltage transformers, bushings, capacitors, and surge arresters.
This model has also undergone an aesthetic upgrade: the previous version was relatively bulky and took up more floor space, whereas the current suitcase-style version is much more compact. A customer from Anhui has purchased one unit of our MC6000B dielectric loss tester!
1. The instrument employs Fourier-transform digital filtering technology to measure capacitance, dielectric loss, and other parameters. It delivers highly accurate test results and is well-suited for automated measurement.
2. The instrument employs variable-frequency technology to eliminate 50 Hz power-frequency interference on-site, ensuring reliable measurement data even in environments with strong electromagnetic interference.
3. Equipped with a large, full-touch LCD display for simple operation. The fully touch-enabled LCD screen features an oversized graphical user interface, providing clear and intuitive visualization of every step in the process, so operators can use it without requiring additional specialized training. Simply tap the screen to complete the entire measurement procedure.
4. Data Storage: The device is equipped with a calendar chip and high-capacity memory, enabling it to save test results at any time, allowing users to view historical records at will, and supporting printout functionality. Both the current time and the stored time can be displayed and printed at any moment.
5. Scientific and Advanced Data Management: Instrument data can be exported via USB flash drive and viewed and managed on any PC using dedicated software.
6. The instrument is easy to operate, with the measurement process fully controlled by a microprocessor. Once the appropriate measurement mode is selected, data acquisition is automatically completed under microprocessor control.
7. Integrated model with built-in standard capacitor and high-voltage power supply, facilitating on-site testing and reducing the need for on-site wiring.
8. The instrument boasts high measurement accuracy, fully meeting the requirements for oil dielectric loss measurements; therefore, oil dielectric loss can be measured simply by equipping it with a standard oil cup and dedicated test leads.
9. Equipped with reverse-connection low-voltage shielding functionality, enabling 10 kV reverse-connection dielectric loss measurement of C11 without disconnecting the leads when the 220 kV CVT busbar is grounded.
10. Capable of performing AC withstand voltage tests. Convenient for performing AC withstand voltage tests on the secondary sides of PTs and CTs, as well as for conducting withstand voltage tests on 400 V low-voltage systems.
11. The instrument can identify external high-voltage power supply frequencies ranging from 40 Hz to 300 Hz, allowing for the use of power-frequency power supplies or series-resonant power supplies to conduct large-capacity, high-voltage dielectric-loss tests.
12. Equipped with CVT testing functionality, it supports self-excitation testing of CVTs and allows setting four protection limits for high-voltage voltage/current and low-voltage voltage/current, thereby ensuring the safety of personnel and equipment.
13. During CVT testing, the instrument can automatically measure both the capacitance and dielectric loss of C1 and C2, as well as the total capacitance and dielectric loss of the CVT device.
14. Equipped with CVT ratio measurement functionality, capable of measuring CVT ratio, polarity, and phase error.
15. Equipped with a built-in thermal printer for printout, a calendar clock for convenient test report generation, and USB flash drive output capability.
16. Equipped with a computer interface. One computer can control up to 32 instruments and can be integrated into a comprehensive high-voltage test vehicle to enable measurement, data processing, and report generation.
17. Grounding protection function: when the instrument is not properly grounded or the grounding is poor, the instrument will not enter the normal operating sequence and will not output high voltage. Overcurrent protection function: the instrument will remain undamaged in the event of a short circuit or breakdown in the test specimen.
18. Electric shock protection function: When the instrument operator accidentally experiences an electric shock, the instrument will immediately cut off the high voltage, thereby ensuring the safety of the test personnel.

A customer in Shanxi has purchased one set of our MCYZ-308 zinc oxide surge arrester tester!
The live-testing instrument for zinc oxide surge arresters is used to evaluate the electrical performance of each phase of a zinc oxide surge arrester (MOA). This instrument is suitable for on-site live testing of zinc oxide surge arresters across all voltage levels, as well as for factory and acceptance tests conducted in the laboratory under de-energized conditions. By measuring parameters such as total current and resistive current, it can promptly detect hazardous defects, including internal insulation moisture absorption and valve element aging, in zinc oxide surge arresters.
