PT & CT

Accuracy high precision: Current transformers are known for their exceptional accuracy in measuring current. They provide reliable and precise readings even under varying load conditions. Read this guide to learn more about the current transformer accuracy class.

Safety isolation: CTs provide electrical isolation between the primary circuit (high current side) and the secondary circuit (low current side). This isolation enhances safety by preventing high currents from reaching measuring and monitoring equipment.

Wide range of applications versatility: Current transformers are suitable for a wide range of applications, from protecting electrical equipment to monitoring power consumption in industrial processes and renewable energy systems.

Reliability durability: CTs are robust and designed for long-term use. They can withstand harsh environmental conditions and continue to provide accurate measurements.

High accuracy: RCTs are known for their exceptional accuracy, making them ideal for critical applications such as metering, protection, and control. The toroidal shape minimizes external magnetic fields, ensuring that the secondary current is a highly accurate representation of the primary current.

Low burden: RCTs typically have a lower burden compared to bar-type transformers, meaning they can be used with a wider range of secondary loads without affecting their accuracy. This is particularly beneficial in applications where the secondary load is variable or high.

Reduced size and weight: The compact design of RCTs often results in smaller and lighter units compared to bar-type transformers. This can be advantageous in installations where space is limited or where the transformer needs to be mounted in a specific location.

Enhanced reliability: RCTs are generally more reliable than bar-type transformers due to their robust construction and reduced susceptibility to external factors. The toroidal shape helps to protect the secondary winding from physical damage and environmental influences.

Higher current and power densities: Even when in a small, sealed space, the current transformer can reach high current densities of 30A per each module and can offer high power density with the semiconductors and inducers packaged together.

Optimal heat dissipation: Heat can increase when at higher frequencies and when there are more components. The small size, interturn ratio loss of the windings, and uncomplicated design of the short thermal passages allow the transformers to have ample surface area-to-volume ratio for easy heat transfer capabilities. The transformers are capable of working in high ambient temperature environments of up to 120-130 degrees Celsius (248-266 degrees Fahrenheit).

Simple design: A high frequency current transformer does not come with a lot of parts and has fewer windings. This allows for the transformer to be used for more applications by a wide variety of industries. They are convenient for automatic applications that require little operator handling.

Smaller size: Due to the straightforward design, these transformers can come in smaller sizes without impacting the conversion frequency. You are able to use it in settings where there is limited space while taking advantage of its full operating capacity.
