Resistance Tester Megohmmeter and Shaker
Megohmmeter and shaker are two names for one thing. They are used to measure insulation resistance. They are hand-cranked and easy to carry (commonly used).
Insulation resistance tester, used to measure insulation resistance, digital, high-precision and multi-function (can also measure voltage, etc.) Insulation tester is a pointer or digital display that automatically rises and falls voltage. It can automatically measure insulation resistance, polarization index, absorption ratio, also called digital megohmmeter.
The shaker is a pointer-type instrument that manually raises and lowers the voltage. It can measure insulation resistance, and the error is larger than that of insulation resistance tester. Also called a megohmmeter.
Megohmmeter is a general term for insulation resistance tester and shaker.
1. Different definitions
Megger: Megger is commonly known as megger. Most of meggers are powered by hand-cranked generators, so it is also called the scale of megger in megaohms (MΩ).
It is a measuring instrument commonly used by electricians. It is mainly used to check the insulation resistance of electrical equipment, household appliances or electrical lines to ground and between phases to ensure that these equipment, electrical appliances and lines are working in a normal state and avoid electric shock casualties and equipment damage. wait for the accident.
Shaker: Shaker, also known as megaohm resistance meter, is a megaohm resistance meter used to measure the insulation resistance of various electrical equipment in order to avoid accidents. The megohmmeter is convenient and reliable for measuring insulation resistance.
2. Different composition
Megohmmeter: Megohmmeter consists of medium and large scale integrated circuits. This watch has large output power, high short-circuit current value, and many output voltage levels (each model has four voltage levels).
Shaking table: Shaking table consists of a hand crank, voting and three binding posts (ie L: line terminal, E: ground terminal, G: shield terminal).
3. Different applications
Megohmmeter: Megohmmeter is a commonly used and indispensable instrument for electric power, post and telecommunications, communication, electromechanical installation and maintenance, and industrial enterprise sectors that use electricity as industrial power or energy. It is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment.
Shaking table: widely used in coal mine installation and maintenance, is used to check the insulation of motors, electrical appliances and lines and measure high-value resistance.
