Turns Ratio Testing
-
The transformer turns ratio test, or TTR test, confirms that the transformer has the correct ratio of primary turns to secondary turns. Using this test correctly can help to identify tap changer performance, shorted turns, open windings, incorrect winding connections and other faults inside transformers. Megger’s range of TTR testers are robust to withstand the harsh conditions that some transformer testing in. The range includes varying features to simplify and speed up testing as well as 3 phase TTR testers and PT and CT TTR testers.

90-Degree Optical Hybrid
-
Six-port hybrid devices have been used for microwave and millimeter-wave detection systems since the mid-1990s and are a key component for coherent receivers. In principle, the six-port device consists of linear dividers and combiners interconnected in such a way that four different vectorial additions of a reference signal (LO) and the signal to be detected are obtained. The levels of the four output signals are detected by balanced receivers. By applying suitable baseband signal processing algorithms, the amplitude and phase of the unknown signal can be determined.

High Frequency Transformers
-
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.

LV Iron Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.
