A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, ...

In many power systems around the world, a major transformation is underway. Proportions of synchronous generation, generally from coal and gas-fired power plants, are rapidly reducing. At the same ...

One concern some observers raise about the growth of inverter-based resources, such as solar, wind, and battery storage, supplying the power grid is that they don’t provide inertia. Inertia has ...

Massive integration of inverter-based renewable energy systems has been displacing conventional generating units (mainly synchronous generators) and causing a reduction in power system inertia. This ...

In simple terms, inertia refers to the energy stored in the rotating masses of synchronous generators, typically found in traditional thermal power plants. This stored kinetic energy acts as a cushion ...

Many voltage regulators are of the fixed output variety and include the voltage divider internal to the regulator. There are definite advantages to this approach, which allows active voltage trimming ...

The evolution of today’s Power over Ethernet (PoE) and Power over Data Line (PoDL) systems. The fundamental power delivery characteristics of PoE and PoDL and how these digitally integrated, ...

Energy markets are undergoing some massive transitions. Growing demand for electricity, when combined with the need to limit carbon emissions, drives a huge increase in renewables. This growth is ...
