Devices, components, assemblies and hardware associated with the design and development of electronic equipment. Includes active and passive components, enclosures, interconnection, optolectronics, power and subassemblies.
Demonstrating its commitment to meeting the changing test requirements of utilities and other organisations that operate high-voltage (HV) and extra-high-voltage (EHV) power cables, Megger has opened a new test, development and manufacturing facility in Radeburg, near Dresden in Germany. This adds a further 400m² to the already large site.

The H_RN-2W and H_LT-2W series are designed for applications where a group of polar power supplies are isolated from the input power supply in a distributed power supply system on a circuit board.
The effects of the changes in Germany’s energy policy are already being felt. Together with the photovoltaic systems installed in southern Germany and various biogas facilities, the countless wind turbines along the north German coast should cover at least 35 per cent of Germany’s total energy requirements by 2020. As this OMICRON Magazine article explains, REpower tested a new generation of high-performance offshore wind turbines at selected locations, although they were initially ...
Many Linear Technology devices use an external PNP transistor to sense temperature. Common examples are the LTC3880, the LTC3883 and the LTC2974. Accurate temperature sensing depends on proper PNP selection, layout and device configuration. This application note reviews the theory of temperature sensing and gives practical advice on implementation.
A ubiquitous problem with every industrial plant is the interface of plant measurement signals to the monitoring and control systems. Unfortunately for many plants, this is the single biggest area of weakness — and with the success of the organisation depending on these measurements, more attention should be afforded to the integrity of signal conditioning systems. This paper from Omniflex provides practical guidelines on when and how to introduce signal isolation into 4–20mA loops ...
Voltage transformers (VTs) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration of the objects before installation. The accuracy classes of VTs are different for protection and metering transformers and are classified depending on the maximum ratio and phase-angle error between the vectors of the primary voltage and the secondary voltage related to the primary side.
The safe, fast charging of NiCad batteries is attractive in many applications. Short charge time requires high current. A potential difficulty with high-current charging is battery heating. Excessive internal heating degrades the battery and can cause venting to the outside atmosphere. As Linear Technology explains here, fast-charge schemes based on monitoring cell voltage during charge suffer because cell voltage is not necessarily indicative of the battery’s charge state. Additionally, ...
PC-board layout determines the success or failure of every power supply project. It sets functional, electromagnetic interference (EMI) and thermal behaviour. Switching power supply layout is not black magic, but is often overlooked until it is too late in the design process. Fortunately, physics is on your side.
