When talking about current measurement devices in electrical systems, “CT” or Current Transformer is a term familiar to electricians and engineers. But did you know that there are several types of CTs to choose from? The one that’s ideal for installation in load panels or systems that don’t require electrical system dismantling is the Split Core CT.

Today, Dako will help you understand the Split Core CT in an easy-to-grasp way, guide you on how to choose the right one, and explain why many professional electricians prefer DAKO for their CT needs.

1. What is a Split Core CT?

A Split Core CT is a type of current transformer that can be "opened and closed" around a live wire or busbar without the need to remove the wiring from the system.

Functions of a CT:

Converts electrical current (Primary Current) into a signal that measuring instruments can read
Helps monitor electrical loads in systems, detect overloading, or perform energy analysis

2. Why Choose the “Split Core” Type?

No need to dismantle the system or remove wires → Easy installation without disassembling components in the electrical panel
Ideal for retrofit installations and maintenance
Easy to relocate and reusable
Fits easily into narrow load panels

3. How to Choose the Right Split Core CT for Your Work

Conversion Ratio (CT Ratio): e.g., 100/5A, 300/5A
Window Size (size of hole for wires)
Accuracy Class: e.g., Class 1, Class 0.5
Insulation and Safety Standards

4. Why Choose Dako’s Split Core CT?

Strong and Durable Construction: Secure locking, no loose connections
Accurate Conversion: Supports Class 1 and Class 0.5 accuracy standards
Wide Range of Current Ratios: From 30/5A to 5000/5A
Quick and Easy Installation in 1 Minute: No need to remove wires, no special tools required
Affordable Price: Comparable quality to European brands with faster shipping from stock, ideal for both maintenance and new projects

A Split Core CT may seem like a small device, but it plays a crucial role in measuring and controlling electrical loads.Choosing the right CT ensures accurate readings, system safety, and saves technicians time. If you haven’t tried DAKO’s Split Core CT, now is the time to give it a try.
