megohmmeter
A megohmmeter is an electrical testing device used to measure the insulation resistance of electrical equipment and wiring. It applies a high voltage, typically between 250 to 5,000 volts, to assess the integrity of insulation materials. This helps identify potential issues that could lead to electrical failures or hazards.
These devices are commonly used in industries such as construction, manufacturing, and utilities to ensure safety and compliance with electrical standards. Regular testing with a megohmmeter can prevent equipment damage and reduce the risk of electrical shocks, making it an essential tool for electricians and maintenance professionals.
