Smartgrid: Why adding RTTR to Distributed Temperature Sensing?

Real Time Thermal Rating (RTTR) or Dynamic Cable Rating removes all uncertainty left by the DTS. The DTS measures the real time temperature at the sheath or jacket of a cable. The sheath temperature gives a good idea of the temperature of conductor, but unless an accurate model for the conductor is provided there will be some uncertainly left. The uncertainty is small during steady state operation, but it could be (very) large during an emergency situation. The following figure illustrates the… Continue

Death & Destruction of a Fluke Multimeter



I found a very entertaining video in which Electronics Engineering Video blog host David L. Jones tries to see just how much punishment the Fluke 28-II multimeter will take and still function. It's a fun video (but some of the drops and tosses are almost painful to watch). You can check it out at…

Introduction to Vibration



In simplest terms, vibration in motorized equipment is merely the back and forth movement or oscillation of machines and components, such as drive motors, driven devices (pumps, compressors and so on) and the bearings, shafts, gears, belts and other elements that make up mechanical systems.

Vibration in industrial equipment can be both a sign…

Troubleshooting commercial lighting loads



Commercial lighting loads are a major load for large facilities. Troubleshooting them can often be challenging but it's important to evaluate these circuits for both 1) energy conservation and 2) power quality purposes. They are wired single phase, with the loads connected from phase to neutral. Typically, the phase-to-phase voltage is 480V,…

(Almost) Frictionless Micro Linear Motors?

Traditional linear motors were designed by essentially rolling out a permanent-magnet rotary motor into a linear, flat machine. But a new micro linear motor re-imagines this traditional design with the added benefits of reduced component wear and a significant decrease in friction.


Read all about it here:…

Bimba to Introduce Electric Actuators



Come April, well known and respected fluid power company Bimba will

introduce a line of electric actuators. And this jaded old editor

might be forgiven for thinking they're pretty excited about it, with

language like this in the draft press release:

“This is our most exciting new product launch in more than 10

years,” said Scott Meldeau, Bimba's VP Sales and Marketing. “Now

we can meet our customers' electric actuation needs with the same

value for which… Continue

Microsoft launches cyber attack

Microsoft Corporation convinced me this week that I should buy a new Apple computer. At least when something goes wrong with an Apple computer, I can take it to the nearest Apple store and get it repaired, whether the problem is with the software or the hardware. But when I install an on-line security software update from Microsoft and it totally disables my Dell or Hewlett Packard computer, I have no quick and easy solution to getting it fixed. The hassle is endless.



For example,… Continue

hybrid collector

In this systems production of both electricity and hot water is done simultaneously. In PV modules, as the module temperature increases, the efficiency of the module drops down. In hybrid modules, the module heat is

absorbed in order to produce hot water. In this way, PV efficiency is optimized

as the heat is transferred into water for hot water production.



Solimpeks Corp.has launched its Volther hybrid photovoltaic-solar thermal collector,…
