Let RESA Power Help You Find the Current Transformer That’s Right for Your Power System

Current Transformers are an essential part of managing and monitoring your power systems. They allow you to measure current on circuits that would otherwise overpower the power meters if the current was measured directly. Not only does accurately measuring power output allow the operator to assess load capacity and equipment performance, it is also invaluable for companies that are moving towards energy-saving operations.

Solid-Core Current Transformers

Solid-Core Current Transformers are designed with a fully closed ring around the conductor. To ensure smooth installation, the conductor must be disconnected and then fed through the core of the transformer. Usually employed in newly installed applications, these low voltage Current Transformers are typically the more cost-effective and precise choice.

Split Core Current Transformers

Split Core Current Transformers cater to operations where disconnecting the conductor isn’t favored. The core of these medium voltage current transformers is split, allowing easy placement around the conductor with minimal disruption. Ideal for retrofit installations, the cost of these transformers can be higher than solid-core current transformers due to their added benefits.

Solid-Core Low Voltage Vs Medium Voltage CTs

When it comes to choosing between solid-core low voltage and medium voltage CTs, it’s important to consider the specific needs of your system.

Solid-Core Low Voltage Current Transformers

Solid-core low voltage current transformers are often the go-to choice for industries requiring currents up to 1,000A. Known for their reliability, cost-effectiveness, and high precision, these transformers are easy to install, suiting a wide range of applications. An important factor to remember, however, is their substantial size, which can be challenging in limited-space applications.

Split Core Medium Voltage Current Transformers

Split Core medium voltage current transformers handle higher voltage levels and can accommodate currents up to 10,000A. Commonly used in power distribution systems, they maintain accuracy even under high voltage conditions. Their compact size is ideal for applications with limited space, though they may be more expensive and require specialized installation and maintenance compared to low voltage transformers.

The Right Current Transformer for Your Needs

When choosing between solid-core low voltage and medium voltage CTs, it’s important to work with an experienced electrical engineer who can help you determine which type of CT is best for your system based on its specific needs and requirements. Factors to consider include the voltage level, current range, accuracy requirements, and space limitations.

No matter which type of CT you choose, it’s important to select a high-quality product that is reliable and fits your system’s needs. Proper installation and regular maintenance can also help ensure accurate and reliable current measurements over time.
