Measurements International Ltd.
The measurement of electric power and energy at high voltages and currents at low power factors is becoming increasingly important economically as a way to reduce costs in an ever-growing industrial economy. Today the transformer purchaser subjects the transformer manufacturer to an economic penalty for losses that occur in load and no-load conditions. To keep these penalties as low as possible, it is important that the manufacturer accurately measure these losses. Failure to do so can result in the manufacturer losing important contract awards to their competitors who may be utilizing a more accurate system. Using “State of the Art” proven two-stage-currentcomparator technology, the AccuLoss™ Series of transformer loss measurement systems is designed to meet the needs of today’s transformer manufacturer by providing the most accurate power loss measurement system in the world. Designed for power frequency testing and calibration, the AccuLoss™ system can be used for testing small, medium and large power transformers as well as motors and turbines up to 400 Hz. The system is also ideal for R&D facilities. The AccuLoss™ system can also be used to measure losses in single and three phase reactors.

Keystone Compliance
Electrostatic discharge testing, also known as ESD testing is an essential test for many product. Electrostatic discharge can cause a number of problems including but not limited to mechanical failures, coal dust explosions, fuel vapor explosions and bodily injury. ESD is the sudden transfer of electricity between to electrically charged objects. This electrostatic transfer can be caused by contact, dielectric breakdown or an electrical short. ESD testing simulates various electrostatic impacts that equipment might experience either during transit or operation. The impact of electrostatic discharge can be significant whether the ESD even is so slight that is undetectable by hearing or sight or as spectacular as electrical sparks or lightning. An electrostatic discharge test determines whether a product is in compliance with its ESD protective area and procedures. Electronics manufacturers must identify ESD-reducing measures when their products are either susceptible to ESD or likely to create ESD. These measures can include establishing electrostatic protective areas that are free of static, controlling humidity, using measures to eliminate charging such as avoiding highly charging materials and taking steps to remove static such as grounding human workers or requiring antistatic devices. An ESD test confirms that the equipment correctly operates per the test requirement and the manufacturer’s operating procedures.

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.

TWR-H Series -
IBEKO Power AB
Handheld TWR-H device is DV Power single-phase instrument designed for measuring transformer winding resistance and turns ratio.The instrument has two output DC sources for measuring transformer winding resistance. The first DC source can output up to 2 A DC and is used for injecting current to the transformer’s high voltage winding. The second DC source can output up to 10 A DC and is used for testing the transformer’s low voltage winding. This is especially useful when measuring winding resistance of distribution transformers. These transformers have large turns ratio and therefore a big difference between resistances of high voltage and low voltage windings. Upon the winding resistance test, it is also possible to demagnetize the transformer core. The demagnetization process is completely automatic and safe.Together with the turns ratio, the instrument also measures excitation current and phase shift. This enables detecting transformer core or winding turns failures which cannot be spotted by measuring turns ratio only. The instrument can output test voltage up to 40 V AC for this test, but it can also output a very low test voltage of 1 V AC which is necessary for turns ratio verification of the majority of current transformers.TWR-H is powered by an internal Li-Ion battery. Up to 100 tests can be performed with a fully charged battery.

Hill Engineering, LLC
Fatigue engineering is subject to uncertainty, and data from well executed tests are used to validate conclusions made by analysis and to provide a basis for structural certification. Our staff have extensive experience in testing materials and components under slowly varying, static loads, and under rapidly varying cyclic loads. Tests under static loads are used to assess material properties or to assess the load-deformation behavior of structural components. Tests under cyclic loads provide time to crack initiation, time to failure, or measurements of crack growth over time. We have extensive experience in measuring fatigue crack growth behavior in metallic materials. Past programs have measured crack growth with microscopy and photogrammetry at the surface, cracked area with direct current potential drop, and through-thickness crack profiles with quantitative fractography. By assessing crack growth with a variety of experimental methods, we enable robust analysis validation for cases of complex cracking. Our capabilities in fatigue engineering allow for careful design of a fatigue test program. Whether the tests use constant amplitude loading or an irregular loading spectrum, we specialize in engineering the test that meet your needs. Much of our experience is in non-standard test programs, which require engineering to optimize the test setup. Few others match our capability and experience in fatigue test engineering.

Jinan Testing Equipment IE Corporation
With over 15 years of proven reliability in the world’s most demanding testing environments, the Model 3543 extensometer is designed to survive in those applications where standard axial extensometers would not. Designed by Epsilon, the Model 3543 was created to survive specimen failure by separating into two halves, thus preventing permanent damage to the module body. During operation, the upper half of the extensometer pulls out of the main body. Tapered measuring beams activate strain gaged flexures within the unit. This unique design allows long measuring ranges, yet retains compatibility with electronics for strain gaged transducers. These models offer high accuracy and are light weight but rugged, with low operating force. They are tension only units.The units have hardened tool steel knife edges. Standard quick attach wires provided with the extensometer work on flat specimens up to 12 x 31 mm (0.5 x 1.25 inch) and on rounds up to 25 mm (1 inch) diameter. Optional quick attach kit wire forms are available for use on larger samples. See Model 3542L for long gauge lengths with smaller measuring ranges.The Model 3543 extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers.

Model 3565 -
Jinan Testing Equipment IE Corporation
The Model 3565 uses hard conical points to contact the bolt at the center of the head and at the bottom. It is fully adjustable for different length bolts ranging from 25 mm (1 inch) in length to 150 mm (6 inches) standard. Extension beams are available for longer bolts. The standard maximum measuring range is 1.25 mm (0.05 inches). Generally, on longer bolts this extensometer will be self-supported without requiring any centering marks or punch marks on the bolt. For shorter bolts these marks may be required. If the conical pins are sharp, marks are often not needed even on the shortest bolts.The extensometer has a zero adjustment screw to adjust the length between the contact pins. This is used to set the output voltage to zero, which corresponds to the correct starting position for the test. It also includes a breakaway lower arm. In the event a bolt should fail, the breakaway arm snaps free, helping to prevent damage to the extensometer. This is easily re-installed. In the event that bolt failures are likely during a test, it is recommended the user attach a cord around the upper part of the beam and tie the other end to the test frame to prevent the extensometer from falling. The conical point contacts included with the extensometer are made from tungsten carbide.The Model 3565 extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller. The signal conditioning electronics for the extensometer is typically included with the test machine controller or may often be added.
