Pachyderm Leg Ailment = Diagnosis=20 with Infrared Thermography [top]

Something just = wasn=92t right with=20 one of the Bowmanville Zoo=92s oldest attractions, Vance the = pachyderm.=20 Vance, a 29-year-old Asian elephant was exhibiting symptoms of leg = troubles. Weighing in at almost 10,000 pounds and displaying = majestic=20 5-foot tusks, Vance literally is one of the biggest attractions at = the=20 zoo.

Bowmanville Zoo Attraction Vance the Elephant

Zoo curators=20 Wendy Korver and Michael Hackenberger had been noticing Vance's = reluctance=20 to apply his full weight on his front right leg. It was unsure = however=20 exactly what part of Vance=92s large right leg was the problem. = Irritation=20 in either of the foot, knee or hip joints would all cause Vance to = favor=20 the leg as he was doing. An attempt to use infrared thermography=20 inspection techniques as a method of pinpointing the location of = Vance=92s=20 leg woes was suggested. Knowing the exact location of irritated, = inflamed=20 tissue offers great advantages to the Zoo owners and veterinary = staff in=20 hopes of correcting the elephant=92s condition. Widely accepted in = the=20 equine field for diagnosis of various conditions in horses, = infrared=20 thermography is capable of detecting small surface temperature=20 differences. By displaying the temperature differences as an = image,=20 thermography can zero in on inflamed and irritated = tissue.

On = October 21,=20 2001 under overcast skies, an infrared thermal imager was turned = on and=20 pointed at Vance. Instantly it was noted that Vance=92s right = front leg was=20 indeed the problem and was seen =93operating=94 at an elevated = temperature. A=20 closer look and a few adjustments of the imager's temperature = spans for=20 better temperature resolution indicated the source of the troubles = (click=20 the images for a high resolution version.)

Right side - inflammation located in front right = leg,=20 specifically the lower foot area

<= FONT=20 size=3D1>Front feet - Here the front right foot is easily = compared to=20 the left foot. Problem area is the right lower foot area = (white=20 section)

Front left leg - elevated front left temperatures = noted.=20 Suspect cause: left leg taking weight not supported due to = front=20 right foot problem.

Vance had a=20 sore front right foot. Down at the base of the foot, on the right = front=20 side. Infrared images of the bottom of Vance=92s huge front feet = were also=20 taken to rule out any foreign object concerns such as a nail or = sharp=20 stick as the cause of the front foot irritation. The images of the = bottoms=20 of Vance=92s feet did not indicate any irritation and Vance=92s = veterinary=20 staff could concentrate on the front right foot condition. Further = inspection of Vance=92s bulky frame also located a smaller = irritation on=20 Vance=92s rear right foot and front left shoulder. Both conditions = are=20 suspect linked to the front right foot condition and Vance=92s = favoring of=20 the leg over the recent past. Corrective action by the zoo=92s = caretakers=20 has been developed and put into action to help Vance=92s foot = troubles.=20 Thermography will be used in follow up examinations to study and = prove the=20 effectiveness of treatment.

Aviation applications please
I am=20 interested in finding any sites that may assist me in finding = new ways=20 to utilize our camera in the aviation area. I found the lock-in=20 thermography page but it lead to another question. which is can = the p-60=20 be used in this application and if so where can I research the=20 procurement of a thermal wave source, and instruction on = utilizing this=20 technique?
Solar Collector measuring with IR camera = ?
I'm Working in a Solar Institute and i have to = measure the=20 Heat losses inside the Solar Collector ( Thermal) by using an = Infrared=20 Camera and this collector have a GLASS cover which cause too = much=20 problems to measure the heat loses inside by an IR camera ,so = I'm=20 suggesting to remove the Glass cover and replace it by a Teflon = ,or=20 Makloron cover .so my question will it work or not and why = ?
Water In Subgrade
Has = anyone had any=20 luck detecting water infiltration below an asphalt surface? More = specifically, water in the subgrade below a road surface and = being able=20 to trace the source.
Best marking to put on tank for IR level=20 measurement
What is the best color = or=20 material to put on a tank to be able to use an IR photo of the = tank to=20 see the feet and inches of material in the tank? I thought black = would=20 work best on a white tank but tests have shown that black does = not work=20 real well. Would reflective tape would well?

Does anyone = have=20 any experience with this?
Uneven loads
What would = typically be=20 the problem if only one phase of a 3 phase circuit was showing a = temperature difference(30-40 degree F difference) throughout the = entire=20 system (into breaker and out through starter to motor)? =

Amperage=20 readings are: L1: 19.2, L2: 20.9, L3: 13.2.

I guess my = question=20 is what would cause the uneven loads between adjacent phases and = what=20 percentage of difference should you expect to see?
Motor wiring and net efficiency
I know=20 how to use the ITC provided indirect power loss tool for = specific=20 shapes, but I'm wondering if there is any kind of rule of thumb = approach=20 for conservatively estimating the hit to efficiency in = situations where=20 you find a motor running hot throughout its entire = circuit.

The=20 example I'm looking at right now is a 100HP booster pump in a = municipal=20 water supply system. The motor is on a VFD even though it is = generally=20 running under a fairly consistent condition near full load. The = operator=20 indicates that most of his VFD equipped motors run hotter than = he'd like=20 them to. This particular motor runs warm but not alarmingly so, = but the=20 primary conductors are running >45=B0F over ambient on a warm = day.=20

I'm suggesting this is a probable deficiency that = warrants=20 further investigation, but my problem extends a little deeper.=20

I'm doing this work for a local energy authority, and my = specific task here is to identify not so much hazards or = maintenance=20 issues as to identify and, to the extent that it's possible, = quantify=20 energy savings opportunities.

So what I need to figure = out is,=20 given the information above, how can I come up with a ballpark = figure=20 representing the energy being wasted by the poor condition of = this=20 motor, beyond just measuring the heat coming off its constituent = parts=20 and converting from watts to dollars? If a motor is supposed to = be=20 premium efficiency rated at 92% but it's running like this, can = we=20 assume a 5% or 10% or worse hit in efficiency? What's the best = way to=20 quantify this without overstating the case?
Inactive cable
Has anyone = out there=20 had any experience performing infrared inspection on feeder = cables in=20 manholes. What we're looking to do is to identify inactive = cables as=20 opposed to cables carrying load in a = manhole.

And of course=20 if YOU have a question or want to start a discussion on a = topic, we=20 would love to hear from you. Just post a new thread on a mes= sage=20 board.
