Containerised Switchrooms
A containerised switchroom is essentially an entirely complete electrical switchroom installed within a standard-sized container, usually either 20 or 40 feet in length. Rather than having to construct an entirely conventional switchroom using materials such as concrete or masonry, an entirely complete switchroom is...

RTU – Why They Are Important for Remote Monitoring Systems?
An RTU is a compact computer that assists in controlling and monitoring equipment in factories and other large systems. It gathers information from equipment and reports it back to a control system. Hence, it is important to maintain seamless operations. What Does an RTU...

Pilot lights – Why Are Indicator Lights Important?
Indicator lights or Pilot lights are small lamps that indicate if a machine or device is on or off. Lights tell people whether an object is on, on standby, or if it is faulty. Pilot lights appear on control panels, instrument panels, and on...

CT Accuracy Class – Why does it matter?
When you look at the nameplate of a current transformer, one of the most important things you’ll see is the ct accuracy class. At first glance, it might look like just a number—something like 0.5, 1.0, or maybe 5P10—but this small label actually tells...

Instrument Safety Factor (ISF) – Why do we need to know this?
Instrument Safety Factor, or ISF, is one of those CT concepts that often gets mentioned but not always fully understood. In simple terms, ISF defines how much current a current transformer will allow to pass to its secondary before it starts to saturate and...

CT Saturation – Why is it important?
CT saturation is one of those concepts that sounds complicated at first, but once you understand it, everything about current transformers starts to make more sense. In simple terms, CT saturation happens when the core of a current transformer can no longer accurately reproduce...

How to Select the Right Current Transformer (CT)
Selecting the right current transformer isn’t just about picking a ratio that matches your load current. In practice, it’s about making sure the CT performs accurately, safely, and reliably under both normal and fault conditions. A lot of issues in metering and protection systems...

How to Calculate CT Burden (Step-by-Step Guide)
By now, you already know that CT burden is the total load connected to the secondary of a current transformer. This includes meters, relays, and the resistance of the connecting wires. But here’s the key point: CTs are only accurate when they operate within...
