Megohmmeters

Megohmmeters (also known as insulation testers, or meggers) are used to analyze the condition and measure the electrical resistance of various materials, equipment, and circuits. They perform quick, routine tests that help improve products and hastens the time in which a company may want to release their inventions. By testing the electrical resistance, one may be able to find undesired short circuits and open circuits present in their system that may hinder their ability to function effectively. Closed circuits and insulation materials may also be tested for efficiency. This information is inestimable in value when putting industry standards into scope; every customer wants a good product, but overall a safe and dependable product.

GAOTek Megohmmeters are reliable, first-class devices that can be used to detect weak or deteriorating insulation, moisture accumulation, faulty wiring, and acid formations in the system before they can cause irreversible damage. They are designed to perform at the finest degree, which is paramount to any capital ranking company or top-notch technician. Where one megohmmeter may not test as well, GAOTek megohmmeters can make up for where they lack. Unlike ohmmeters, they are ideal for testing for larger equipment that requires higher rates of electricity to flow through their circuitry. Without a well-functioning megohmmeter, one can put their business at risk. GAOTek is a reliable company that produces the most affordable solutions to your technical needs, and GAOTek megohmmeters are no exception to our excellence.

Technologies

A megohmmeter measures resistance in megohms (millions of ohms), which is required when testing materials that must retain a higher electrical resistance. A standard ohmmeter or multimeter will not have the capacity to provide the appropriate voltage required to test such equipment, thus a megohmmeter is needed in the workplace to complete sufficient testing. Depending on the standards one aims to achieve, the most appropriate resistor values are generally between 1 to 10 megohms.

GAOTek megohmmeters can be designed to create direct currents or alternating currents along with low amperage currents to pass through the resistors using an internal battery, then measures the voltage drop in the tested sample. The premise of this action is to put the materials under a brief stress in order to accentuate any subtle weaknesses present. Our GAOTek megohmmeters are a solid solution for troubleshooting, which will help accurately identify and prevent potential failures in a system. Typically, if the material tested has a lower electrical resistance then it will be riskier to use in the field. However, if the resistance is too high then the material may not be suitable to protect the equipment; it may very well prevent the electrical current from flowing through the system. A megohmmeter must have the capacity to generate voltages that range from 50 to 50,000 volts to be the most accurate; it is crucial that one has the best equipment available on the market. This is why our GAOTek machine is a valuable asset when developing modern technology, and is highly recommended in the testing phase of high-quality electrical products.

GAOTek Megohmmeters can be used to help meet a collection of industry standards. Given the requirements or modern day certifications, it is an understatement to say how important it is to have a reliable megohmmeter on hand. A few of these standards are as follows:

·       IEEE Recommended Practice for Testing Insulation Resistance of Rotating Machinery (IEEE Standard 43-2000)

·       ICEA Standard for Optical Fiber Outside Plant Communications Cable (ICEA.S-87-640)

·       IEC Power Cables With Extruded Insulation And Their Accessories For Rated Voltages From 1 kV (Um = 1,2 kV) Up To 30 kV (Um = 36 kV) – (IEC 60502-1)

·       UL Standard for Electrical Resistance Trace Heating for Commercial Applications (UL 515)

·       IEC Electrical Equipment for Measurement, Control, and Laboratory Use (IEC EN 61010-1 )

·       ESD Compliance Verification Of ESD Protective Equipment And Materials (ESD TR53-01:2015)

As standards change, our devices evolve. GAOTek megohmmeters are the best choice when it comes to meeting industry standards and more
