subject: How To Measure Electricity Using Ac/dc Clamp Meters [print this page] As the world moved from hand-operated equipments to machines, electricity became a vital part for almost all industries. In fact, now it seems almost impossible to run a factory without constant and good quality supply of power.
However, irregularities taint most power supplies. When these cross a certain limit, they can be harmful. Fluctuating or failed power could mean loss of hours of productivity or, worse, damage of expensive machinery. Thus, you need to monitor the flow of power on a regular basis to pre-empt a problem with the same. One of the ways in which you may do that is with the help of a clamp meter or current meter.
What Is a Clamp Meter?
A clamp meter is a device used for measuring or testing electrical currents. It is a regular voltmeter with two clamps or probes at its head. This helps you get an accurate reading of the electrical equipment without having to physically connect with it. These current meters are usually used to read and measure alternating current (AC), but with an advanced version you can easily identify the direct current (DC), too.
Earlier these ACor DC clamp meters could be found only in the analog variety. Today, they are available in the digital format, too, to facilitate easier analysis and accurate outputs. With added features, they are amongst the most popular tools for electricians and technicians.
How Can You Measure Power Using a Clamp Meter?
To measure power or troubleshoot, connect the clamps around the wire or other conductors. Try and measure a single conductor at one time, so as to get easy and accurate readings. Next, pass small amounts of power to start with and check for consistencies. Eventually, you may introduce large amounts of electricity to understand the power quality or error with the equipment. Usually you would find DC or AC clamp meters with a connection to a power outlet. This helps mainly in troubleshooting as you may measure single or multiple conductors.
Normally used for servicing, installation and maintenance, these are ideal for checking power quality as well as defects in industrial equipments and electrical controls, overall electrical systems and industrial HVAC. Invest in a quality clamp meter in your manufacturing facility to protect your machines from damage.
