Traductoare de curent cu miez solid vs. cu miez divizat

Current transducers are used to measure the current in a circuit and are a key component of every power monitoring system. Common examples include Hall current sensors, fluxgate current sensors, Shunt Resistor Transducers, Current Transformers, Rogowski coils, etc.

Current Transducer Types

There are two main types of current transducers: Solid core traductoare de curent și Split core current transducers. The main difference between solid core and split core current transducers (CTs) is how they are installed.

Solid core current transducers

Require the conductor to be disconnected before installation. They have a permanently closed, toroidal (donut) shaped core that the conductor must pass through. Solid core CTs are often used in new installations and are more accurate than split core CTs. However, they can be difficult to install in tight spaces or in situations where the electrical system needs to remain operational.

Split core current transducers

Have a hinged core that can be opened and closed to pass the conductor through without disconnecting it. Split core CTs are often used in retrofit installations because they are easier to install and don’t disrupt the wiring. However, they may be less accurate than solid core CTs.

Choosing the right current transducers

When choosing between a solid core and split core CT, you can consider things like:

Acuratețe și precizie

Precizia se referă la cât de aproape sunt citirile traductorului de curentul real. Precizia se referă la consecvența cu care traductorul furnizează aceeași citire pentru același curent.

High accuracy ensures the transducer gives correct readings, while high precision means it consistently provides those correct readings. Look for a transducer with low error margins and minimal variations in its measurements.

Acest lucru este deosebit de important în aplicațiile critice în care este necesară monitorizarea precisă a curentului, cum ar fi în sistemele de alimentare sau în echipamentele sensibile.
Solid core CTs are generally more accurate than split core CTs.

Environmental Conditions, Mounting and Installation

Consider the operating environment, including temperature range, humidity, and potential exposure to chemicals or vibration, and choose a transducer that can withstand these conditions.

Ensure the transducer’s mounting and installation requirements align with your system’s capabilities and constraints. Isolation is also one of the factors in choosing sensors. Ensure the transducer provides adequate electrical isolation for safety and to prevent signal interference.

Split core CTs are easier to install and don’t disrupt the wiring.

Cost and Effective

The cost of the sensor is a significant factor, especially in the design phase where companies aim to lower costs and reduce risks. There is a choice between off-the-shelf sensors, which are generally more cost-effective, Solid core CTs are generally less expensive than split core CTs.

Use case

Solid core CTs are better for critical monitoring, while split core CTs are better for installations where power shouldn’t be disrupted.
