Instrument for measuring insulation resistance

Instrument for measuring insulation resistance

Answer:

In the course of power consumption, there is safety in electricity, in electrical equipment, such as motors, cables, household appliances, etc.. Modern life is changing with each passing day, and people can not live without electricity. One of their normal operations is the degree of insulation of their insulating material, i.e., the value of the insulation resistance.
An instrument for measuring insulation resistance is a ohmmeter.
When heated and damped, the insulation ages. Its insulation resistance is lowered. Thus causes the electrical equipment leakage or the short circuit accident occurrence. In order to avoid accidents, the insulation resistance of all kinds of electrical equipment is often measured. Determine whether the insulation meets the equipment requirements. The measurement of general resistance is usually done in two ways: low voltage measurement and high voltage measurement. The insulation resistance due to the general value of higher (usually a trillion European level). Measurements at low voltage cannot reflect the true insulation resistance at high voltage conditions. The ohmmeter is also called an insulated resistance meter. It is the most common instrument for measuring insulation resistance. It has a high voltage power supply when measuring insulation resistance, which is the difference between it and the resistance measuring instrument. The ohmmeter is used to measure insulation resistance, which is convenient and reliable. However, if it is not used properly, it will cause unnecessary errors in measurement, and we must correctly use the ohmmeter insulation resistance to measure.
