It is known from the fundamentals of electrical engineering that current must always be measured in a line to a consumer, since the maximum current is determined by the smallest resistance in the electrical network. However, it is often not possible to split the circuit with a multimeter in order to measure the current, or the current in the alternating power supply system is very high so that a contact current measurement is not possible. That is when a clamp meter is needed.
How does a clamp meter measure the electrical current?
Around each electrical conductor, through which the current flows, a magnetic field spreads linearly regarding the flowing current. In case of the direct current, this is a DC magnetic field and, in case of the alternating current, an alternating magnetic field. Clamp meters use this effect and measure the current via a Hall sensor (direct current) or via a kind of transformer (alternating current), depending on the current type.
Which clamp meter should be used?
The selection of the clamp meters depends on various factors. The first factor is the nature of the current. The clamp meter for alternating current is most widely used. For applications, when also the direct current is to be measured with the help of a clamp meter, for example, to measure the current of a starter in a motor vehicle, a clamp meter, which can measure the direct current, is needed. Commonly, the clamp meters, measuring the direct current, are also able to measure the alternating current.
Another question to consider when selecting the right clamp meter, is the amperage. Generally speaking, the higher the current to be measured, the bigger the size of the clamp meter. A special design of a clamp meter is the Rogowski coil. This type of a clamp meter is often used for very high alternating currents, since very large sizes can be achieved here. Flexible clamp meters are also frequently used for the measurements in the control cabinet.
Besides, clamp meters are frequently used for measuring the electrical power. This particular form of the clamp meter is widely used in the electrical measuring technology. The following must be considered here. The measurement with the help of a clamp meter is always possible only if in a 3-phase network, all conductors are loaded in the same way, i.e. symmetrically. For asymmetrically loaded phases, 3 clamp meters must be used. Here, PCE Instruments offers appropriate clamp meters with power measuring functions.
A special measuring function in a clamp meter is the so-called inrush function. This function is always used when the starting current of the machines or motors must be measured. The clamp meter is in a kind of standby mode after activation. As soon as the current is detected by the clamp, it is detected with a very high sampling rate and displayed on the screen, also if the current is again on a different level after switching on.
Further special functions such as voltage measurement or resistance measurement and temperature measurements complete the range of functions of a clamp meter.
