Techimp HQ S.r.L
New IEC standards, IEC 60034-18-41 and IEC 60034-18-42, have been issued to define the procedures for testing partial discharge inception voltage and the long-term performance (endurance) of Type I and Type II insulation systems used in rotating machines fed from voltage converters. Voltage impulse generators are required at least to test turn insulation, but they would be recommended for any testing under power electronics supply because of their capability to simulate the real electrical stress conditions. More generally, any type of electrical insulation system when subject to impulsive voltage waveform during life should be carefully evaluated in terms of partial discharge and endurance behaviour. This is why voltage impulse generators able to provide impulses with controlled amplitude and frequency are needed to face this new testing challenge.

Mini-MAX-Series -
Qualitest International Inc.
The MINI-MAX, Ultrasonic Bolt Tension Monitor, defines the state of the art in the measurement of the actual elongation produced by tightening a threaded fastener. The MINI-MAX can measure the elongation very accurately in fasteners of virtually any material from 1/2 inch to 4 feet in length. The measurement is achieved by determining the change in the transit time, of an ultrasonic shock wave along the length of the fastener as the fastener is tightened by any method. The on-board microcomputer automatically interprets this time measurement to display the time(nanoseconds), elongation, load, stress, or %strain from stretching a fastener. Through the use of high speed digital signal processing and automated diagnostics, the MINI-MAX minimizes the requirement for extensive operator training. With built in data recordation and reporting through an RS232 interface, the MNI-MAX offers an easy to use and reliable solution to the most difficult bolting problem.

ASTM D149 -
National Technical Systems
This test method covers procedures for the determination of dielectric strength of solid insulating materials at commercial power frequencies, under specified conditions. Unless otherwise specified, the tests shall be made at 60 Hz. However, this test method is suitable for use at any frequency from 25 to 800 Hz. At frequencies above 800 Hz, dielectric heating is a potential problem. This test method is intended to be used in conjunction with any ASTM standard or other document that refers to this test method. References to this document need to specify the particular options to be used. It is suitable for use at various temperatures, and in any suitable gaseous or liquid surrounding medium. This test method is not intended for measuring the dielectric strength of materials that are fluid under the conditions of test. This test method is not intended for use in determining intrinsic dielectric strength, direct-voltage dielectric strength, or thermal failure under electrical stress (see Test Method ASTM D3151). This test method is most commonly used to determine the dielectric breakdown voltage through the thickness of a test specimen (puncture). It is also suitable for use to determine dielectric breakdown voltage along the interface between a solid specimen and a gaseous or liquid surrounding medium (flashover). This test method is similar to IEC Publication 243-1. All procedures in this method are included in IEC 243-1. Differences between this method and IEC 243-1 are largely editorial. Note: The above information is taken directly from the test method Scope published in ASTM D149.

Marposs S.p.A.
Marposs complements its geometric measurement solutions with solutions for non-destructive testing using eddy current technology.The testing options can be divided in three large groups:Material integrity test, to check for the presence of defects (cracks, porosity, blow holes, inclusions) on the surface and in the layer just below the surface.Material properties test, to check if the thermal cycles (hardening, hardening and tempering, annealing, stress relieving, etc.) have been performed correctly. Material identification checks are done to sort parts with the same geometry but made with different materials.Thread inspection to check if the treading has been carried out and its quality.In addition to the non-destructive checks performed with the eddy currents, we have developed a durometer for the conventional measurement of surface hardness, according to the Rockwell scale (HRC or HRA); which uses a diamond penetrator to measure the hardness of the sample being tested.

SCR ELEKTRONIKS
Every electrical apparatus or machine consists of two distinct sections - one which carries the electricity, and other which is isolated (insulated) from the electric currents. The former may be called the `Live' side whiles the latter `Earth’ side. A person near about the apparatus or handling it can safely touch the Earth side, but not the live side, for obvious reasons. To ensure that the isolation of the two sections is effected properly, the apparatus is tested by subjecting it to a Voltage much higher than the normal working Voltage. If the insulation is good, it stands the test without breakdown otherwise high electrical stress punctures the insulation at its weakest spot foretelling a later calamity to unwary user. Government Department- when buying electrical equipments- and all reputable manufacturers test every piece of equipment by this test called HIGH VOLTAGE TEST. It weeds out poorly insulate apparatus.

Torontech Group
Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers then have a tough resin buffer layer and/or core tube(s) extruded around them to form the cable core. Several layers of protective sheathing, depending on the application, are added to form the cable. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between the fibers, or reduces flare in fiber bundle imaging applications Optical fibers are very strong, but the strength is drastically reduced by unavoidable microscopic surface flaws inherent in the manufacturing process. The initial fiber strength, as well as its change with time, must be considered relative to the stress imposed on the fiber during handling, cabling, and installation for a given set of environmental conditions. There are three basic scenarios that can lead to strength degradation and failure by inducing flaw growth: dynamic fatigue, static fatigues, and zero-stress aging.
