I’m happy to announce that Aim Dynamics has partnered with Sentran Corporation to provide exciting new lines of UL Listed current transformers.
Ease of Shipping Sunday, July 23, 2023 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 than others but it is important for me to try to anticipate how long I’ll need to complete each order because the shipping is mostly completed in the afternoon that way we can include any orders that come in through the course of the day.
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 coil. It’s a new product designed to help reduce the error seen when Rogowski coils are placed on conductors close to the connector. In addition, they can be used in tight situations because of their small size.
What would you like to see a video on next? Please share your feedback.
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 coils are similar; they output 131 mV per 1000A at 60 Hz, and 109.2 mV per 1000A at 50 Hz.
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. This system not only allows for centralized control, but also better monitoring or device performance in order to provide more economical energy usage.
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.
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 easier to manage current that can be easily monitored.
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.
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
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 measurement. In addition, they tend to be less expensive than their closed loop counterparts. Electricians and engineers prefer to use open loop current sensors in a battery powered circuit because they have a low power requirement to operate.
