The Importance of a Digital Low Resistance Ohmmeter

Megger DLRO10HD 10A Digital Low Resistance OhmmeterLow resistance measurements are a valuable part of electrical system reliability. This type of testing helps to identify high impedance electrical connections that can result in excess heating, losses and potentially failure of power system components.

Environmental factors are significant contributors to the deterioration of metallic joints and bonding points. Pitting, corrosion and other contaminants can causes an increase in resistance between electrical contacts or bonding points, increasing heating and electrical losses. If neglected, it may lead to eventual failure. Resistance measurements of terminal connections, bus bars, relay contacts and other components with metal junctions should be a part of a regular maintenance program and ensures continuous operation of your electrical system. It is a wise idea to invest in a DLRO so you can regularly assess the condition of your electrical system. 

If you are thinking of investing in electrical test equipment, you might want to rent first so you can decide on what model and brand you should purchase. This gives you the opportunity to evaluate the tools in your electrical facility without buying them. Consider renting from Protec Equipment Resources to get excellent rental service and technical support. Contact us for additional information about our equipment rental service.
