Digital Megger Insulation Resistance Tester , Find Complete Details about Digital Megger Insulation Resistance Tester,Digital Megger Insulation Resistance Tester,Insulation Tester,Insulation Resistance Tester from Other Electrical Instruments Supplier or Manufacturer-Programma (Wuhan) Electric Equipment Co., Ltd.
Digital Megger Insulation Resistance Testerdedicated to the measurement of watercooled generator test, but also can be used for laboratory or field testing insulation testing . The maximum output voltage of 2500V. Includes highprecision microcurrent measurement system,digital boost system. Just use a highvoltage lines and a signal line connecting the test product can be measured. Automatic measurement, the results from the large screen liquid crystal display, and store the results.
1) Using microcomputer control, menu operation, large-screen LCD display, low voltage shielding measurement, stable performance, is an intelligent instrument.
2) Automatic measurement of R15, R60, R600, automatic calculation of absorption ratio, polarization index.
3) Test voltage is negative high voltage 2500V, with a strong load capacity. The resistance between the winding and the manifold (water resistance) is as low as 70kΩ, the test voltage drops <10%.
4) Measuring range of 0 ~ 10GΩ, automatically switch the range.
5) Can automatically compensate and eliminate the polarization potential of water on the test results. When the resistance between the manifold and the stand is as low as 3kΩ, the measurement accuracy can be ensured.
6) The simulation of the combination of the pointer and the digital display shows the trend of the data and the accurate measurement results.
7) The test time is displayed at any time, and the buzzer automatically prompts every 15 seconds.
8) Automatic completion of the measurement of high pressure, high pressure release time of not more than 5 seconds.
9) Automatically measure ambient temperature, air humidity, and date and time for each test.
10) Can save 60 sets of measurement results, and the data 20 years without loss.
11) With RS232 interface, can communicate with the computer data; comes with the printer, the measurement results can be printed, eliminating the meter reading work.
12) With a comprehensive protection, high reliability of the work.
