Handheld Turns Ratio & Winding Resistance Tester TWR-H -
Amperis sl
TWR-H is a handheld, battery operated, fully automatic test set specially designed for turns ratio, phase shift, excitation current and winding resistance measurements of transformers. It can also perform demagnetization of these transformers. Transformer turns ratio is determined by applying AC voltage across high voltage winding, accurately measuring AC voltage across the corresponding unloaded transformer winding, and then displaying the ratio of these voltages. User can enter a transformer’s nameplate voltages, so that turns ratio deviation can be calculated. This feature eliminates any error otherwise caused by an operator’s manual calculation. TWR-H compares measured turns ratio with the nameplate ratio and prints out the % of error for each test. Transformer winding resistance is determined by injecting DC current through a winding, accurately measuring DC voltage across the winding, and then calculating resistance as the ratio of voltage and current. The device generates true DC ripple-free currents. Both the injection of the current and the discharge of energy from transformer magnetic circuit are automatically regulated.

Oersted Technology
The Model 300-series magnetizers are designed to handle a variety of magnetizing applications and materials, from small Alnico parts to large blocks of neodymium-iron. Each of these magnetizers feature patented ECS (Electronic Capacitance Switching) technology, which allows the user to change the capacitance of the unit through the front panel. By setting the charging voltage and capacitance of the magnetizer properly, the user can then scale the output energy of the unit to match the magnetizing fixture being used. The 300-series magnetizers also includes a peak current meter, which automatically captures the peak current of the magnetizing pulse once it occurs. A safety circuit internally discharges the capacitor banks if mains power is removed from the magnetizer or if the cabinet is opened during operation. When connected to a suitable magnetizing fixture, the magnetizer is able to disable its front panel controls if the fixture overheats. Other features include a lockout keyswitch and a current sense output jack (this connects to an oscilliscope for viewing of the magnetizing pulse). All 300-series magnetizers can be modified for computer control, photocell trigger, or autocharge operation.

Inframet
Solar blind UV cameras are imaging devices optimized to detect ultraviolet light of wavelengths below about 280nm. Such cameras are insensitive against sunlight due to negligible sensitivity to visible and long wavelength UV light. Solar blind UV cameras are used in a series of applications like corona detection, fire detection, combustion analysis, plasma research, testing UV lamps, etc. However, highly sensitive corona detection is the main mass application and these devices are of crucial importance in electric power industry. These imaging devices enable easy detection of degraded insulators of high voltage transmission lines, distributions and substations. They can see the emission of UV light when discharges occur at defect insulators. From design point of view solar blind UV cameras are actually bispectral imaging systems built by combining true UV camera with typical visible camera. These bispectral imaging system generate output image as overlay of typical visible image with UV image of analyzed UV source.

RMO-TW Series -
IBEKO Power AB
RMO-TW series is perfect for winding resistance measurements of inductive objects. It is ideal for testing transformer windings (power transformers, distribution, autotransformers) and for on-load tap changer verification. In addition, any RMO-TW transformer ohmmeter & tap changer analyzer can also perform transformer demagnetization.The series contains 4 models, with maximal test currents from 10 A (RMO10TW) to 50 A (RMO50TW). They are fitted in a portable and lightweight metal housing.All transformer ohmmeters from RMO-TW series generate a true DC ripple-free current with automatically regulated measurement and discharging circuit. The injection of current and discharge of energy from the test object are automatically regulated.Three independent channels enable testing of three windings in series. Consequently, this enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.DV-Win software enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test. Finally, a user can export all results in the form of a report.

DEM60C -
IBEKO Power AB
After a DC current test, such as winding resistance measurement, the magnetic core of a power or instrument transformer may be magnetized (remnant magnetism). It can cause various problems such as wrong diagnostics, inaccurate measurements on a transformer, inrush current at the start-up of a power transformer, or incorrect operation of protective relays due to magnetized CT cores. The best way to eliminate this source of potential problems is to use demagnetizer on the power or instrument transformer.The DEM60C is a fully automatic test instrument which performs three-phase transformer demagnetization. Transformer magnetic core demagnetization requires the application of AC current with magnitude decreasing to zero. DEM60C provides this AC current by internally changing the polarity of a controlled DC current. During the demagnetization process, the instrument supplies the current at decreasing magnitude for each step, following a proprietary algorithm. It can demagnetize single-phase and three-phase power transformers.The instrument can be connected to all three phases of a power transformer to be demagnetized, on either the primary or the secondary side. If a user selects specific vector diagrams for different types of transformers, DEM60C will run a specific demagnetization procedure for each transformer type (i.e., single phase, delta, wye/star, zig-zag.) without switching the test leads.DEM60C enables safe and efficient power transformer demagnetization. The instrument automatically regulates the injection of current and discharging energy from the inductance. During and after the operation, an intrinsically safe discharge circuit with an indicator rapidly dissipates the stored magnetic energy. The discharging circuit is independent of the power supply, which improves its reliability in case of loss of power.Test currents of up to 60 A DC enable efficient demagnetization of even the largest power transformers. Using a DV Win software, it is possible to control DEM60C externally.
