Multiple-Turn Primaries Saturday, July 22, 2023 When measuring DC currents with a transducer, it isn’t uncommon to encounter operating currents that are too small to provide an input that is within the transducer’s optimal measurement range.
We recently stocked a new line of AC current sensors with a 5A output that are UL registered. Made by Magnelab, the new line covers amperage ratings of 100-2400A. The devices are up to 0.5% accurate, depending on the amperage and burden.
Truth be told, modern society would not be the way it is today if not for the transformer— not the robot, but the special electrical component that’s being used in practically every home and commercial establishment today, even after centuries have passed. Have you ever wondered, however, when the contraption was first invented?
It’s something that even experienced electrical engineers forget at times: never operate a current sensor with the secondary winding in an open circuit. Doing so results into catastrophic overvoltage failure of the transformer, which usually manifests as arcs bridging the gap between the terminals. Aside from overvoltage, this error can also cause insulation failure, which increases the chances of a fire breaking out.
Given the planet’s dwindling resources, energy needs to be saved—and there are several ways to go about it. One is submetering to make people more conscious of their energy consumption.
Electric current is a flow of electric charge typically occurring in electric circuits and such energy is carried by moving electrons in a wire. Electric current may also be carried by ions in an electrolyte or by both ions and electrons like that in a plasma. For monitoring purposes, an AC current sensor can be used to detect electric current and measure it in amperes using a device called an ammeter.
There’s no denying that electricity is an important part of modern life. Without the ability to control and measure it, however, people cannot harness its full potential.
As much as electricity has been a true boon for mankind, it is equally dangerous when it isn’t harnessed properly. This is why many people’s hearts skip a beat when they see a downed power line blocking their path. Unfortunately, that is exactly what happened in Portland, Oregon recently. An article from KATU provides more information:
Power is everything in electronic and mechanical systems, but you need to cut down utility bills whenever possible. In an article for data storage industry portal Server Watch, writer Paul Rubens explains
Centralized power may be a good thing but there are times when people using a facility must shoulder part of the responsibility and obligations, which are mostly made possible by submetering. An August, 2010 article in The Electricity Forum states as much about an apartment complex in New York City’s Greenwich Village
