A Megohmmeter or insulation resistance tester, is a special type of ohmmeter used to measure the electrical resistance of insulators. [1] . Insulating components, for example cable jackets, must be tested for their insulation strength at the time of commissioning and as part of maintenance of high voltage electrical equipment and installations.

2024年5月21日 · A megohm is a unit of measurement that describes electrical impedance. Meg- is a slightly shortened prefix for mega, which is 1x10 6; -ohm is the basic unit, which is represented by the Greek letter omega (Ω). A megohm, therefore, is an impedance measurement that represents one million ohms.

One megaohm is equal to 1,000,000 ohms. A megaohm is the resistance across a conductor with an electrical potential difference of 1,000,000 volts with one ampere of current flowing through it. The megaohm is a multiple of the ohm, which is the SI derived unit for electrical resistance.

What is a Megohmmeter? The megohmmeter (or megger) is an instrument for measuring very high resistances, such as the insulation resistance of electrical cables. A high voltage source is required to pass a measurable current through such resistances.

The megohm scale is an easy-to-read log scale graduated from 0.1 to 1000MΩ. The ohm scale is linear with a range from 0 to 10Ω. The Model 1015 comes complete with carrying case, shockproof rubber housing, a pair of color-coded leads, with black test probe, red alligator clip. spare fuse, batteries and a user manual.

The Model 1015 comes complete with carrying case, shockproof rubber housing, a pair of color-coded leads, with black test probe, red alligator clip. spare fuse, batteries and a user manual.

The Model 1015 is an analog instrument with four easy-to-read scales. The megohm scale is an easy-to-read log scale graduated from 0.1 to 1000MΩ. The ohm scale is linear with a range from 0 to 10Ω.

The AEMC 1015 Analog Megohmmeter is a compact, self-contained, battery-operated True Megohmmeter. This practical, dependable and rugged insulation tester can be used for a broad range of plant and field service applications and is designed for use in harsh environments.

The megohm scale is an easy-to-read log scale graduated from 0.1 to 1000MΩ. The ohm scale is linear with a range from 0 to 10Ω. It permits insulation resistance testing at 500V and 1000V, and resistance measurements up to 1000Ω.

A megohm is a unit of electrical resistance equivalent to one million ohms (1,000,000 Ω). It is commonly used in electrical engineering to measure high resistance values, particularly in insulation testing and circuit applications.
