Unlike a direct current (DC) where the magnitude remains constant, the frequency wave of AC currents varies at around 50 and 60 times a minute. This enables the electrons to travel longer distances and deliver more power. DC currents cannot reach longer distances unless their voltage is increased.

AC electricity is better for supplying power because the voltages can be easily increased or decreased with the use of a transformer. It is easier to use electric devices like lights, television sets, and refrigerators. DC currents easily heat up and burn, thus making AC currents cheaper and safer.

Electricity is measured by AC current sensors like inductive sensors. These are electronic proximity sensors with a core wound up in wire and signal conditioner. They can detect metal objects without touching them, and can be used for measuring the current used in traffic lights, residential power, and other industrial processes for automation.

Measure strain– Equipment suffers wear and tear. Having electricity pass through something puts it through strain that may cause it to break. Knowing exactly how much voltage is being passed through can help detect any emerging problems.

 Prevent overloads– Too much power can be bad, especially for sensitive equipment. Voltage transducers ensure that the right amount of voltage is delivered to each system. This preserves equipment and prevents future malfunctions.

The Current Transformer

A current transformer’s main function involves providing an alternating current from a source, and its basic anatomy involves a core material which produces magnetic electricity as well as two windings: a primary coil that takes the input electrical energy, and a secondary one that receives the alternating current.

Solid versus Split Core

Most current transformers come in two types: solid and split core. As the name suggests, the former is a single core that cannot be opened and repaired unless the entire power source is shut down. In cases where this isn’t an option though, the split core provides the alternative, since it can be handled by professionals without having to cut the power.

Applications

AC current sensors play a significant role in the complex process of power generation and distribution. The concept and device are largely involved in successfully accomplishing the tasks of any system or equipment that needs constant power supply.

What is AC?

AC stands for alternating current or the back-and-forth flow of electrical current (as opposed to a single flow linked to direct currents or DC). Power plants supply AC to residential and commercial users. The constant change in direction is so fast that whatever is powered by the grid (say, a light bulb) cannot stop functioning unless power from the source is stopped.

What does the AC current sensor do?

As with other types of sensors, an AC current sensor’s main function involves measurement. The device measures the waveforms that ACs produce and convert it into a readable numerical value or voltage. Current is measured as it passes through the sensor and onto a load, or to a transformer which can manipulate the voltage of the AC as needed before distributing it.

What are the benefits of using an AC current sensor?

If you work in the power distribution industry or in any field that utilizes high-voltage equipment, then there is one instrument that you are very familiar with: current transformers. After all, these peripherals are vital for measuring the current that flows through any given system, which prevents overloading and all the problems associated with it.

Given the important task that current transformers perform, choosing a type or brand is no small matter. If you’re in the market for these instruments, here are three good reasons to consider split-core models:

Perfect Retrofit Solution

If you already have existing power lines that need measuring, a split-core current transformer is the perfect retrofit solution. Thanks to their design, these transformers can simply be snapped onto a conductor. Trusted brands have self-locking mechanisms that ensure a tight, reliable fit.

No Need to Disconnect

Other current transformers require the power line to be disconnected before they can be installed. This isn’t the case with split-core transformers since they are “snap-on” measuring instruments. Their ease of installation means there is no downtime whatsoever.
