Transformer Test Equipment
-
DV Power test instruments perform various diagnostic tests on power and instrument transformers. Even more, a unique feature is a condition assessment of on-load tap changers. Performing a transformer test before their breakage can be crucial.Test instruments are portable and enclosed in durable metal cases. Also, the 19” rack-mounted version suitable for factories is available as well.Applications supported by DV Power transformer test equipment include:Winding resistance measurement (IEC 60076-1)Analysis of on-load tap changers (IEC 60214-1)Heat run test (IEC 60076-2)Automatic transformer demagnetizationTurns ratio measurement of power and instrument transformers (IEC 60076-1)Excitation current measurementPhase angle measurementTransformer vector group detectionDemagnetization status verificationAll of the above-mentioned measurements are performed with the highest accuracy.The advanced DV-Win PC software collects both numerical and graphical results. As a result of that, these features provide an easier and more efficient analysis. After the test, DV-Win software generates a test report with a single click. Furthermore, a user can easily customize the test report and save it in different formats, such as XLS or PDF.Finally, the analysis of on-load tap changers is performed by the new method called dynamic resistance measurement (DRM). This is a non-intrusive method. Therefore, it allows detecting problems in on-load tap changers without disassembling them.

Shunt Voltage References
-
Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.

Voltage Variation Simulator
KES7400A
-
The KES7400A Series comes in a single cabinet that consists of a Signal Generator module (including an arbitrary pulse generator), which combines our power supply technology and EMC technology, and a high-speed bipolar power supply module. Many automotive electronic devices have long wire harnesses and inductive load characteristics, as do motors, or capacitive load characteristics with a large-capacity capacitor connected between the input and ground. In the case of these devices, general DC power supplies exceed the linear operation range, potentially making it impossible to obtain the desired waveform output.

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.
