Insulation resistance is evaluated in more than seventy percent of the electrical maintenance testing. Hence, it is vital for any maintenance engineer to buy the insulation testers. While buying a perfect insulation tester, there are few things that should be considered. The issue of overvoltage is one thing which is unwanted and can destroy the equipment or electric circuit under test. Another highlight is the arrangement of a guard terminal which aids to negate the effect of any leakage over items under test. This also helps to avoid the biased result of the test. So, it becomes really necessary to see the voltage limit before buying or using a certain insulation tester.
Further, most of the insulation testers provide test voltages in the range of particularly 250 V, 500 V and 1,000 V. These options are enough for users with primary requirements, but many new instruments provide a wide range of functions. For instance, a 100 V insulation tester cannot be used for pre-testing circuits before going ahead on to a higher test voltage.
Worldwide, digital Megger insulation tester is known equipment, for electrical wiring installation wiring. These insulation resistance testers are the optimal equipment when high voltages are required for analyzing the insulation resistance. The tester provides the optimal voltage regulation and has in-built guard terminal to avoid any surface leakage current from the measurement.
Megger test equipment generate a monitored dc high voltage and use low-zero-drift, high-accuracy circuits, with high current sensitivity. Megger testers are designed portable, each is confined in a molded, constructed case which is resistant to impact and retardant to flame.
You can look at the Megger tester for sale at Omni controls which is the largest online store for test and measurement equipment and work with the world class brands. The company's line of business includes the wholesale distribution of industrial machinery and equipment.
