Insulation Resistance Test Wiring Diagram

Tips: Working principle of insulation resistance tester

Insulation resistance tester, also known as digital insulation tester, Megohmmeter, Megger insulation tester adopts the embedded industrial SCM real-time operating system, with digital analog pointer and digital segment code display in perfect combination. RDDLZ series of Megger insulation meter has a variety of test voltage options, large capacity, strong anti-interference, AC and DC dual-use, simple operation and so on. It is an ideal tool for measuring the insulation resistance of large-capacity transformer, current transformer, generator, high-voltage motor, electric capacitor, power cable and arrester.

Insulation resistance tester is mainly working by using a voltage exciting the tested device or circuit, and then measuring the current generated by the excitation, using ohm's law to obtain the resistance. For example, the testers apply a much higher voltage when making resistance measurements than the ohmmeter capabilities available on a digital multimeter (DMM). Megohmeters usually use voltages ranging from 50V to up to 5kv; a typical DMM has a voltage of less than 10v. For insulation test, it require measuring very large resistance value, the capability up to 10 TΩ, and requires a higher voltage.

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
