Islanding is the intentional or unintentional division of an interconnected power grid into individual disconnected regions with their own power generation. Intentional islanding is often performed as a defence in depth to mitigate a cascading blackout .
Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection. Solar micro-inverters differ from conventional inverters, as an individual micro-inverter is attached to each solar panel. This can improve the overall efficiency of the system.
For safety, grid-connected set-ups must automatically switch off or enter an "anti-islanding mode" when there is a failure of the mains power supply. For more about this, see the article on the condition of islanding.
The publication describes requirements, levels and test methods to achieve immunity compliance of an electronic product. The purpose is to create a reproducible ground for product compliance and the standard defines: ranges, levels, test equipment, setups, procedures, calibrations, generator waveforms and general uncertainties.
The second-largest U.S. producer is partnering with investment firm Engine No. 1 and electric services company GE Vernova on the project. Chevron's announcement comes a day after Chinese startup ...
Illegal border crossings have dropped dramatically from a year ago. U.S. Customs and Border Protection reported fewer than 82,000 migrant encounters in January versus more than 242,000 encounters ...
The possible invocation of the 1798 Alien Enemies Act is also hanging over how Trump’s anti-immigration agenda is being framed so far. That law, which Trump touted on the campaign trail, allows ...
An isolation transformer provides maximum protection when the device is ungrounded. Connecting it to test equipment, for example, an oscilloscope or a benchtop multimeter, may ground the circuit. Electrical isolation is considered to be particularly important on medical equipment, and special standards apply.
