Single-Phase Transformer Winding Resistance Meters

RMO-TD Series

IBEKO Power AB

RMO-TD Series - IBEKO Power AB

Using the most advanced switch-mode technology available today, the RMO-TD series is ideal for winding resistance measurements of inductive objects. Transformer resistance meters and tap changer analyzers are perfect for testing:transformer windings (power transformers, distribution, autotransformers),all types of tap changers,generators,electrical motors,high-current busbar joints,cable splices,and welding joints.In addition, transformer demagnetization can also be done with all RMO-TD instruments.The RMO-TD series contains 3 models, with maximal test currents from 25 A (RMO25TD) to 60 A (RMO60TD).The three independent voltage sense channels enable testing of three windings in series. This enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.All RMO-TD transformer resistance meters have a built-in tap changer control unit. It enables remote control of on-load tap changer (OLTC) directly from the device. In order to make the most out of this feature, DV-Win software is included which can be programmed to do everything automatically – running winding resistance tests and changing OLTC tap positions.The DV-Win software also 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.All results can be exported in the report format.

Osborne Transformer Corp.

Osborne Transformer Corp.

Osborne High Frequency Current Transformers operate at frequencies higher than 50/60 Hertz. Their purpose is to reduce high frequency system currents to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when high frequency current transformers are to be used for power measuring applications.

Techimp HQ S.r.L

Techimp HQ S.r.L

PPS2 provides power supply to the PD detectors installed on HV cable when low voltage AC power is not available. The PPS2 takes the required power directly from the High Voltage power line under monitoring by means of units clamped on the HV power cable(s).PPS2 is designed to withstand High Voltage line failure events such as temporary overload and short circuit conditions. An internal detection and self limiting circuitry guarantees that PPS2 and the connected equipment survives in case of such events.

Yangzhou Power Electric Co., Ltd

Yangzhou Power Electric Co., Ltd

The AC test transformer are especially designed for testing high voltage products and components, such as cables, power transformers, gas-insulated switchgears, bushings and arresters. It is also suitable to test insulation materials. They are used to generate testing high voltage and function as part of the complete system. These systems are particularly suited for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (inductive voltage transformers).

Autoneum Holding AG

Alpha Cabin - Autoneum Holding AG

The Alpha Cabin has been especially designed for the measurement of acoustic absorption properties of materials and components used for the noise insulation of vehicles. The Alpha Cabin is significantly smaller than normal reverberation rooms and therefore ideally suited to use within limited space capacities. The acoustic absorption of the Alpha Cabin itself is also very low: Thanks to the high level of sound insulation, background noise in the frequency range of interest is kept to a minimum.

These multi-element standards consist of multi-layer thin film coatings, one on top of the other, upto a maximum of 6 elemental coatings. It is generally recommended to have coating thicknesses < 20 µg/cm2, so as to cause negligible notable matrix effects, in particular absorption of X-rays emitted in lower deposits by those covering them.
