Power-supply failure takes on significant importance in high-end computer, telecom, medical, and industrial applications, in which uninterruptible power is paramount. In these systems, diode-OR-ed ...

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 ...

At one time, the National Electrical Code (NEC) contained two Articles you won’t find as of the 2020 revision: Art. 280 (surge arrestors) and Art. 285 (transient voltage surge suppressors or TVSS).

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 ...

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 ...

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 ...

Careful design limits overvoltage on the supply input of integrated circuits, and avoids compromising an IC's specifications. Overvoltage damage can cause an immediate failure, or accelerate an ...

Authorities had scrambled to find answers after the April 28 outage Spain and Portugal were hit by widespread power blackouts in April. Officials revealed Tuesday (June 17) that it was caused by ...

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 ...

IN their communication under the above heading, Messrs. Le Brocq and Cocks 1 redirect attention to a point that has been too often overlooked: namely, that the effectiveness of a metal as the cathode ...

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 ...
