I.C.A.S.T. Course
The I.C.A.S.T. 2.5 Day course is focused on making a greater impact in plant inspections programs. The course will cover the following.
Introduction to Predictive Technologies.1/2 day basic theory & instrumentation. 1/2 day leak testing. 1/2 day electrical inspection. 1/2 day mechanical inspection.Best practices.
This course will stress the benefits of the different technologies and how they work in an integrated RCM Program. Every course can be customized to one application or all of the above mentioned.
Knowledge of ultrasound physics.Inspector must have the physical capabilities to use the equipment. Knowledge of safety concerns in the plant that might be encountered while testing.Knowledge of the type of assets being tested.Knowledge of equipment being used to analysis the assets.Inspection techniques to proper test and analysis the data.Experience of inspector. If you don’t use it! You will lose it!

(Air leaks, belt rub, finger guards issue, shoes, rollers)
What is Ultrasound?
Sound is a mechanical wave that travels in a straight line.
A sound wave is a disturbance that moves through a medium.
Requires a medium through which to travel.
Ultrasound is a wave with a frequency exceeding the upper limit of human hearing. Greater than 20 khz (20,000 hertz).
Often described in terms of a sinusoidal plane wave.
12 kHz 50 & younger 16 kHz 30 & younger
Heterodyning
First demonstrated in 1901 by Reginald Aubrey Fessenden.
This is done by shifting one frequency range into another new one.
It also involves the modulation and demodulation of the signal.
It’s the process of taking a raw signal, splitting the high from the low frequency, oscillating the signal, amplifying it and converting it into a translation of high frequency to an audible signal.
Also pioneered amplitude modulation (am) radio.
Reginald Aubrey Fessenden (October 6, 1866 – July 22, 1932) was a Canadian-born inventor, who did a majority of his work in the United States and also claimed U.S. citizenship through his American-born father. During his life he received hundreds of patents in various fields, most notably ones related to radio and sonar.
The Benefits of Ultrasound
Ultrasound is one of the most versatile PD/M testing devices on the market.
Can be used for Annual Cost Avoidance.
Wide range of applications.
Picks up the earliest indications of faults in equipment.
Eliminates background noise through is ability to heterodyne the signal.
Allow the user to isolate the source of the emission quickly and effectively.
How Transducers Work
These transducers have piezoelectric crystal are flex when sound wave strikes them. This is know as a piezoelectric effect. Ultrasound detection devices don’t transmit sound waves they only detect them. These can be found in everything from Watches, Lighters, Camping Stoves, to Ultrasound Detection devices.
Contact Module
Internal inspections
Connected to Piezoelectric Transducer
Acoustic Energy via the Wave-Guide is Converted into Electrical Energy.
Angle of Incidence
Creates a wave mode conversion:
When not at a normal angle of incidence
When ultrasound changes mediums
At interface of new medium(s)
NOTE: airborne ultrasound equipment only receives ultrasound
Angle of Incidence is the Angle that Sound
Interfaces with the Second Medium.
Incident Wave
Reflected Wave
Angle of Incidence
Ultrasound Path Characteristics
Mode conversion causes the Incident Wave to change its characteristics.
Reflected Wave
Refracted Wave
Shear wave is a Transverse Wave
Surface wave is a Rayleigh Wave
Plate wave is a Lamb Wave
Incident Wave Reflected Wave
Mode Conversion Refracted Wave
Shear Wave
Surface Wave
Plate Wave
Reflection
Occurs when a sound waves bounces off a flat surface.
Can be mistake for the source of the incident wave.
Safety Tips
Is the inspector properly trained.
Be aware of pressurization.
LEL levels in the area.
Pressurization exceeding tensile strength.
Fork truck traffic.
Operating around robots.
LOTO.
Quality Assurance
Containment tightness
Airline
Aerospace
Automotive
Marine
Pressure vessels
Tank cars
Vacuum systems
Bulkhead testing
Building Envelope Testing
Pharmaceutical Products
Environment Conservation
Air Surveys help identify leaks that waste energy and contribute to green house gases. Companies can apply tax incentives by reducing their energy usage.Some sites use compressed gases that can destroy the environment.
What does a Steam Trap do?
Steams are designed to hold back steam.
Return condensate to the boiler.
bleed of air.
Mechanical Inspection
Can determine Bearing Faults issues as well as Stray Voltage in a motor.
Identify beginning stages of a fault before other technology.
Will work on slow speed bearing very effectively.
Why Risk Lives Opening Electric Cabinets?
Unfortunately, these actions expose us to electrical faults such as corona and arc, which can cause very serious burns and even death in our body. It is necessary to know when one of our teams is going to fail, but doing so exposing the life of ourelectricians is not the best way to do it, that is why IRISS puts at your disposal our excellent products with which the onesin charge of monitoring all the cabinets online inspections without having to open them.
Electrical Injury
Electrical injuries can allow the current flows from hands to feet to a ground causing damage to:
Nerve center
Vital organs
Heart & lungs
What is Partial Discharge?
‘Electrical discharge that does not completely bridge the space
between two conducting electrodes’
Gas filled voids in solid insulation
Bubbles in liquid insulation
Around electrodes in air (corona)
What is Partial Discharge?
1. (Surface) Tracking – Electrical tracking over contaminated insulator
2. Internal Discharge – Void or defect within component
• Voids within solid insulation
• Across the surface of insulated material
• Within gas bubbles in liquid insulation
• Around an electrode in gas. This is more commonly referred to as Corona
Where does Partial Discharge occur?
