A major power outage in April was caused by grid overvoltage, triggering a chain reaction. The Spanish grid lacked sufficient voltage control capacity, contributing to the blackout. Minister Aagesen ...

The good thing about being a field applications engineer is that you get to work on many different circuits, often all at the same time. While this is interesting, it also presents problems. Jumping ...

Requiring only a handful of inexpensive components, the circuit breaker in Figure 1 responds to both overcurrent- and overvoltage-fault conditions. At the heart of the circuit, D 2, an adjustable, ...

High demands on the robustness of electronic systems, especially in industrial environments, continually present developers with great challenges. Overvoltage protection is one key design ...

A modern distribution system that feeds a facility having a significant environment of susceptible electronic equipment requires protection against lightning-induced overvoltages. And when an overhead ...

Many system applications require that capacitors be connected together, in series and/or parallel combinations, to form a "bank" with a specific voltage and capacitance rating. The most critical ...

POWER OVER ETHERNET (POE) enabled devices and their electronic components are designed for operation within specified current and voltage ratings. If these ratings are exceeded due to short-circuit or ...

Australian scientists have identified seven methods to prevent PV losses when overvoltage-induced inverter disconnections occur. The methods include battery storage, reactive power inverters, export ...

A widespread blackout plunged Spain and Portugal into darkness and has been identified as “one of its kind.” The official report of the European Network of Transmission System Operators for ...

Madrid (AFP) – A major power outage that paralysed the Iberian Peninsula in April was caused by "overvoltage" on the grid that triggered "a chain reaction", according to a government report released ...
