What is a split core current transformer?
Split-core current transformers provide accurate measurements of AC electrical systems and feature a removeable or hinged leg for easy installation without disconnecting wires or interrupting power. Both retrofit and semi-permanent metering applications can benefit from the split-core’s non-invasive design.
How do CTS work?
When alternating current travels through an electrical conductor, like cable or bus, it develops a magnetic field at right angles to the flow of current. If this current is passed through the primary winding of a CT, the iron core inside becomes magnetized which then induces a voltage in the secondary coils.
Why do we use current transformer in relay circuit?
CT- current transformer, is used in the the relay circuits for protection purposes. As the current and voltage ratings in a power system are very high, it is not possible to measure currents and voltages of that high magnitude as they are way too large for any meter of reasonable size and cost.
What is a split core CT?
Split core CTs have a “split” in the core that allows the CTs to be placed around the conductor without having to disconnect the conductor or disrupt the wiring. Split core CTs may be more expensive but their convenience generally outweighs their cost when dealing with retrofit installations.
What is split current?
These split-core current transformers take an AC amperage input and output a corresponding 5A AC amperage signal. DCT Series. These current sensors take an AC amperage input and output a corresponding DC voltage signal.
What is a split core ammeter?
The split-core ammeter is actually an open transformer (that is why it only works with AC) which has a winding on its primary (the lead through which we measure current), and on the secondary a much larger number of windings in order to get low current from the higher one which we, using the resistor, convert into …
What makes a split core transformer split core?
Split-Core Current Transformers. SEL-CTs are designed for applications where it is difficult or uneconomical to open the primary conductor to install a solid-core-type current transformer. The split-core design uses M-6 silicon steel formed into a hexagonal or rectangular shape.
What can you do with a split core switch?
Optional Relay Output, Solid or Split Core Case Current Switch is ideal for monitoring whether fans, pumps, or motors are operating. All models have a built-in solid state output. Applications include BAS and HVAC.
What are the features of a current transformers?
Current Transformers and switches have either solid or split cores as well as relay outputs, LED confirmation, and an adjustable set point. Some models feature an LED for visual confirmation that current is flowing through the device.
What can a field selectable range transformer be used for?
Solid or Split Core, Field Selectable Range Current Transformer is a low cost alternative for measuring power and monitoring the operation of fans, pumps, or other equipment. Applications include BAS and HVAC.
