What is a UL Listed Current Transformer versus a UL Recognized CT?

Posted on

When it comes to current transformer (CT) requirements, approvals and registrations can cause quite a headache for inspectors and installers. Sifting through different products and components to decipher certifications and seals can be quite a challenge, which is why knowing the difference between a UL Listed current transformer and a UL Recognized current transformer is so […]


Regular to Revenue Grade Current Transformers: The difference is in the dollars

Posted on

Not all AC current sensors are created equal. Some are able to measure energy usage with acceptable accuracy, while others can pin down your energy bill to within 0.2%. What makes a Revenue Grade Current Sensor? Typically, current transformers are available in two accuracy classes: standard (or regular) CTs, as well as revenue grade CTs. […]


Wireless CTs Connected to Measurlogic’s Modbus TCP Meter

Ease of Shipping

Posted on

As part of a current transformer distributor that receives orders from all over the world I have sent out a lot of different packages to many different locales.  A good portion of my day includes handling the packaging and preparing of shipping labels for orders.  As would be expected some days take longer to complete this […]


New Rogowski Coil Videos Available

Posted on

I recently created a blog on increasing the output of a Rogowski coil.  To add to the content of that blog post, I’ve also created a video that describes the effect of wrapping a Rogowski coil multiple times around  a conductor. A couple of weeks ago I also added a video on Magnelab’s new “tear drop” Rogowski […]


Increasing the Output of a Rogowski Coil without an Integrator

Posted on

Rogowski coils are convenient, lightweight, and easy-to-install.  However, the output of a Rogowski coil is very low. For example, the RCT-1800-000, made by Magnelab, outputs 70 mV for every 1000A on the primary, when operating at 60 Hz.  If operating at 50 Hz the output is even lower, only 58.33 mV per 1000A.  Dent Rogowski […]


What is Modbus and Why Are Modbus Meters So Popular?

Posted on

Modbus is one of the first and probably one of the most popular systems in use today for creating an intelligent system for controlling electrical devices. Developed in 1979, Modbus is a serial communications system that allows facility managers to control a number of devices from one centralized location using a series of predefined commands. […]


Current Sensing Theory: The Technology Behind AC Current Sensors

Posted on

Ask any electrical professional what the most important piece of equipment he or she carries and the answer you will almost certainly receive is their current sensor. There are different current sensors for DC current and for AC current, and this article will focus on the technology used for accurately assessing AC currents. In any […]


Current Transformer Basics: What You Need To Know About Current Transformers

Posted on

A current transformer is a device that is designed to create an alternating current from a direct current. The device will measure the direct current in its primary winding and convert it to a proportional alternating current in its secondary winding. They are used to reduce a high voltage current into a much smaller and […]


BACnet meters are the key to a successful building automation system

Posted on

Building automation is one way that corporations are not only saving money when it comes to operating their various facilities, but reducing their carbon footprints. So, how does building automation help companies save money by reducing energy consumption? The key lies in the use of BACnet. BACnet is an acronym that stands of Building Automation […]


The Benefits of Using Split Core Transformers

Posted on

If you’re looking at current transformers, you have two main options: split-core transformers and solid-core transformers. A contactless, split-core transformer’s claim to fame is its ability to be snapped over pre-existing wires, making them ideal for retrofitting projects and more. There is no need to screw or weld any type of bracketry, so they are […]


What You Need to Know About Current Sensors

Posted on

When it comes to current sensors, you have two main options: open loop or closed loop. Open loop current sensors can measure either AC or DC current and offer you electrical isolation between the circuit you are trying to measure and the output of the sensor in order to provide you with a more accurate […]
