BACnet protocol is an important part of various automated building control systems, and it is something that needs to be fully understood. If you are new to automated building systems or have never used this protocol before, it is important you comprehend it fully. In this way, you can get the crucial insight you need into this protocol and better understand how it benefits you and your business.
How Rogowski Coils Work
Named after their inventor, Walter Rogowski, the Rogowski style of coils were first developed in 1912. They basically function as a measurement tool that determines the current moving through a conductor that has been inserted within the flexible Rogowski loop. Rogowski coils allows the observer to accurately examine the changes in current over a given […]
DC Voltage Output CT Comparison
If you need an Adc to Vdc transducer, you’ll want to compare the Magnelab DCT series and the Sentran Corp 4DS series. To help you do this, consider the following chart: *May be customized. As response time decreases, ripple increases, and vice versa As you’ll see from the chart above, the Sentran 4DS can be optimized for […]
What is a UL Listed Current Transformer versus a UL Recognized CT?
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
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
Today I hooked up Measurlogic’s DTS-310 Modbus TCP meter to Magnelab’s wireless CT system, the SCT-200W. After getting it set up I created a short video. Here’s the transcript: This is Victor Fehlberg here and today I’ll be showcasing Magnelab’s wireless SCT 200w series. What I’ve got set up here – this is the wireless […]

Ease of Shipping
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
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
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?
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
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
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
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 […]
