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 ...

Crowbar circuits have long been the go-to safeguard against overvoltage conditions, prized for their simplicity and ...

Researchers from King Mongkut’s University of Technology North Bangkok in Thailand have proposed a new methodology to conduct techno-economic assessments of distributed PV systems considering ...

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 ...

IN general, the term overvoltage refers to the difference between the potential required to discharge an ion at a particular electrode and the calculated reversible value, in the same electrolyte.

Learn what types of circuit-protection technologies are required to overcome metal-oxide-varistor limitations in certain harsh environments to increase application reliability and safety. To ensure ...

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 ...

When testing your devices, it may become apparent that the device needs protection against an overvoltage condition. Most power supplies offer some form of overvoltage-protect (OVP) circuit. The OVP ...

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 ...
