#split core current transformers

A transformer is the most efficient electrical device, which is used widely throughout all the industries. It transfers electrical energy from one electric circuit to another, without changing the frequency. The energy transfer generally takes place with a change of voltage and current. So, transformers are used extensively for measuring current and monitoring the operation of the power grid. According to the end user or switchgear manufacturer, current transformer’s shapes and sizes vary.

One of them is Split-core current transformers, which are a perfect fit for energy applications. It either has a two-part core or a core with a removable section. A Current Transformer has a split core that allows you to easily install the CT around the existing bus or cable conductors.  This Split Core Current Transformer is a perfect solution for energy management applications and manufacturing, which is also easy in installation. Split core AC current sensors also have different hole sizes and current ratings to suit any energy application.

There are also different industries that need different models of a current transformer according to their workload. To fulfill those requirements there are many suppliers of current and voltage transformer in the market but searching for the top supplier is a difficult task. To make the process easier, Shandong YUANXING Electronics Co., Ltd. is the leading company in this industry. Whether you are searching for SA Series, SB Series, S series split-core current transformer or for energy, we have all the options for you.

One of the special models we have is the UL 2808 Split Core Current Transformers. This safety standard CT was released in 2012. This is a standard covers open-type split-core current transformers that are intended for field installation within distribution and control equipment to measure current on a branch circuit, for example, switchboards, panel boards, industrial control equipment, and energy-monitoring/management equipment.

Current transformers (CTs) are devices used in railways, electricity transmission and distribution, vessel propulsion, power generation, wind/solar power renewables, and industrial equipment. With various applications come many different purposes for CTs, which include protection, power measurement, interposing, and summation, among other things. So when buying CTs from power monitoring equipment companies, you need to ensure that you buy the right type for your intended application.

The more common current transformers are smaller than a typical apple. However, certain transformers are the size of wet-cell batteries or small towers. These can be commonly found in utility poles and electric substations, where they serve the same purpose of measuring currents in real time.

You can step down the current through several ways. The most common is to design a complete circuit, i.e. a power supply connected to a load and resistor. A simple light bulb doesn't need a resistor because the tungsten filament inside is already one. A LED lamp, on the other hand, does away with the tungsten, thereby requiring a resistor.

Another way is to wind the current-bearing line around a current transformer. Aside from getting the amperage of a supply line, current transformers also step down the current with a few turns of the wire. Think of it as a spiraling water slide; compared to a straight one, a spiraling slide can cut the speed of your slide to the bottom.

Electrocution is a deadly form of accident. Depending on the voltage, anyone making contact with an uninsulated live wire can suffer fatal injury or even death. This is the reason why there are strict safety guidelines on working with high voltage and line powered equipment and wires.

Virtually all electrical measuring instruments, including ammeters (instruments that measure current flow) are susceptible to over fusing or damage resulting in current overload. To protect them from such risks, these devices have to be connected to the source using a current transformer, a device that reduces the amount of current flowing through a secondary winding. Current transformers can either have split or solid cores.

A split core CT is often preferred to a solid core CT due to its efficiency. After all, solid core CT installation normally entails opening the metal buss or the wire before the device can be installed snugly. In addition, the entire system has to be shut down to ensure the installer’s safety. Unfortunately, doing so will impede any production process that relies on electricity.

Demand meters, as the name implies, are installed in residential and commercial properties to help utility companies keep track of their consumers’ power demands. Transformers play a pivotal role in this regard because they must be able to accurately measure a household’s rate of using electricity (in kilowatt) over a period of time (kilowatt per hour). These two variables are needed to measure the household’s overall ‘load factor’, or how often electricity is used. That said, measuring individual or unit load factors of a multi-story building is quite impractical unless mini-transformers are used.

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.
