Current Shunt Resistors - rc-electronics-usa

In the past, an ammeter shunt meant a current shunt resistor put in parallel with the coil of an analog, galvanometer type meter. Automobiles did this. The idea was that only a tiny fraction of the current to be measured passed through the meter, the rest being "shunted" through the current shunt.

SHUNT is precision element for the energy meter which works in all kinds of electrical meter as power measure. The Manganin Shunt resistor is used as a key part of the measuring device inside the electronic ammeter The EBW type shunt gives precise measurement. It also helps to save cost of the production process and ma

Best shunt resistor for power meter application ...

Looking for a shunt resistor for measuring power usage and was wondering if anyone had any experience with these. It should be capable of handling 110V/20A in-home circuit. EDIT: Energy monitors...The key is finding one with low enough resistance that it doesn't have to dissipate much power. Two of these in parallel would do the job: search.digikey/scripts/DkSearch/dksus.dll?Detail&name=TMC5-.10-ND With two in parallel, the resistance will be 0.05 ohms, so at 20 A, you'll have to dissipate 20 * 20 * 0.05 = 20 W. They're rated for 5 W continuous, or 10 W for the two of them. As long as you don't have to maintain 20 A, they'd work fine. I'll see if I can dig up something better. -- Edit: here's a better solution. Try one of these: search.digikey/scripts/DkSearch/dksus.dll?Detail&name=MR50.01FTR-ND The resistance is 0.01 ohms, so at 20 A, you'll dissipate 20 * 20 * 0.01 = 4 W. The part is rated for 5 W continuous, so you're safe.Best answer · 4You haven't stated the accuracy you require or the range of currents you wantto want to measure. If you are looking for a 5% measurement you may want to look at a current transformeror a hall effect device. The nice thing about these is they give you isolationfrom the line. Take a look at the various power meter application notes onthe TI, Microchip and ADI sites. They will probably have some specificrecommendations. For a resistor be careful of the power dissipation. You need to derate for dissipationand you may need to look at the temperature coefficient for accuracy. Also some powerresistors have very specific mounting recommendations -- height off the PCB, the amount ofpower being dissipated by adjacent components. If you need an accurate measurementyou will want a resistor with Kelvin connections (four terminal). If you needa wide range of currents you may also need an instrumentation amplifier.4Ah, you actually want to build a power meter-- take a look at the STPM01. It's an IC designed to be the core of a residential power meter. st/stonline/products/families/analog_and_mixed_signal/interface_ics/related_info/stpm01.htm Digikey has them in stock for $9.94 in qty. 1. You'd need to connect it to a microcontroller of some sort via SPI. I suspect that there are also other ICs like this available-- maybe check Analog Devices, Linear Technology, and TI.2For higher current ranges, such as the one you're looking at, it is probably better to use an inductive pickup. This allows you to measure high currents accurately, without having to dissipate lots of heat from shunt resistors. An example would be the Digi-Key 398-1081-ND , which gives a DC voltage out proportional to the AC current in the system.2If you're just measuring AC, use a current-sensing transformer, such as this EPCOS one from Digikey (or flip through some others ). It offers much lower resistance than a shunt resistor (0.8 mΩ nominally) and provides the added benefit of isolating your sensing circuitry from the mains line. Hall-effect current sensors also offer similar performance, such as these from Allegro , but work with DC as well as AC. Digi-Key carries most of their product offering as well.1The ACS714 from Allegro comes in a common SOIC package and has an internal shunt resistor, so no worries about parasitic resistances in measurement. The ACS714 measures bidirectional currents up to 30A , and outputs 66 to 185 mV/A.1Shunt resistors supposed to be used for DC, for AC suppose to use amper clamps which is the same current transformer.0

Meter Shunts - electronics tutorials

Meter shunts are a useful means of extending the current range of an ammeter. As current divides between two resistors in parallel it is possible to increase the sensitivity of a DC microammeter or milliammeter by paralleling an additional resistance with the inherent DC resistance of the meter itself. This is called a meter shunt
