This Is How To Use A Clamp Meter

General

Clamp meters are commonly used to measure load currents and leakage currents. In using it, it also has its own way. Then how to use a clamp meter to measure the load current and also to measure the leakage current? Meanwhile, before we continue, if you also need to buy a new clamp meter for your company, we recommend you check out some ranked the best rated clamp meters.

How To Use A Clamp Meter To Measure Flow

When measuring load current in a 1-phase 2-wire circuit, the clamp meter should be applied around one (not both) wires. Since the current flowing to and from the load in the two wires forms a pair of opposite magnetic fields, the two magnetic fields cancel each other out, causing the clamp meter to show zero current if the two wires are measured. at the same time. When measuring a 3-phase circuit, it is necessary to measure the current values in the respective wires R, S, and T by applying a clamp meter to each of them in turn.

How to Use Leakage Current Clamp Meter (For Leakage Current)

When measuring leakage currents in 1-phase / 2-wire circuits, a clamp meter should be applied around both wires. Since the current flowing to and from the loads in the two wires forms a pair of opposite magnetic fields, there will be a difference in the two fields if there is a leakage current. The current measured when the clamp meter is applied around both wires at the same time is the leakage current.

When measuring a 3-phase circuit, the clamp meter must be applied around the R, S, and T wires (all three wires) at once. The leakage current can also be measured by applying a clamp meter around the ground wire.

That’s it for the information regarding how to use the clamp meter that we can share with you in this article. We hope this info can help you to use this device properly and safely, so you can ensure the quality of your work and your safety at the same time.
