20 kv digital insulation resistance meter for electrical power systems
 

I.overview
Hz 20kv Digital Insulation Resistance Tester, through the test system in different components of the insulation resistance (transformers, switching devices, wires, motors), you can isolate and repair the failure of components.
It is of great significance to ensure the safety of products and equipment in the quality of products and equipment by using insulation test to test the insulation between the sample and the adjacent conductor.
Before the system is powered by an insulation test verify that it is sound, can improve the performance of the system; insulation test can be found in manufacturing process and equipment defects, and these problems before the equipment failure is generally not found. In the EU, this testing is mandatory, even for the smallest civil system.

II.performance characteristics

7 measurement range is 0 ~10T, automatic switching range.
8 analog bar with the combination of digital display, the image of the data show that the trend of change and accurate measurement results.
9 at any time to display the test time, and every 15 seconds, the buzzer automatically prompts.
10 automatic discharge pressure measurement is completed, the high-pressure discharge time is not more than 30 seconds.
11 automatic measurement of environmental temperature, air humidity and the date and time of each test.
12 can save the measurement results of the 60 groups, and the data can not be lost for 20 years.
13 comes with RS232 serial interface, can communicate with the computer data.
14.RS232 serial port external printer (optional), can print measurement results, free meter reading work.
15 with a comprehensive protection function, high reliability.
