INTRODUCTION
Electrical preventive experiment is an important part in ensuring safe operation and maintenance of power system. MEWOI616 (616A) High Voltage Insulation Tester is an important Insulation diagnosis tool to detect insulation or fault of electrical equipment. MEWOI616 (616A) Insulation resistance tester has the characteristics of large capacity, strong anti-interference ability and easy to carry. It is suitable for testing the electrical insulation resistance characteristics of large high voltage transformer, motor and electrical appliances, long-distance power cable or buried cable under the strong interference of high voltage substation and power plant. |
MAIN FEATURES
| MEWOI616 (616A) Intelligent high voltage insulation resistance tester, with seven measuring ranges optional: 500V, 1000V, 2500V, 5000V, 10000V, 15000V, 20000V, the maximum test can reach 20TΩ, has manual voltage regulation function. |
| 1,Design in strict accordance with safety standards |
| 2,Insulation Resistance Range 20T@15KV(MEWOI616A:20kV) |
| 3,The short-circuit current can be adjusted up to 5mA (up to 10mA short-circuit current products can be customized). |
| 4,Automatic display of polarization index (PI), and absorption ratio (DAR), can test leakage current and capacitance. |
| 5,The anti-jamming performance is superior. When the interference current reaches 2mA, the instrument still guarantees the test accuracy. |
| 6,Capacitance test sample discharges quickly, no manual discharges are needed in cable testing, and the instrument discharges automatically and quickly. |
| 7,Two power supply modes: using lithium-ion batteries for power supply, the duration can reach 4 hours (20000V no-load). At the same time, it can be charged in use. When power failure occurs, AC power supply can be automatically converted to battery power supply. |
| 8,Full English display, prompt operation, simple and clear, and can display insulation resistance analog column. |
| 9,Digital filtering function, when the display value deviates due to external influence, the use of filtering function to mitigate the impact. |
| 10,Perfect protection function and fuse burning prompt function. |
