Production of series of 250 MVA autotransformers rated for power up to and the transformers up to 400 MVA, 330 kV; Production of the first three-phase autotransformer 250 MVA, 500 kV, equipped with in-built on-load tap changer; Production of the first converter transformer 90 MVA for DC transmission line ± 400 kV, Volgograd – Donbas
When testing power supply circuits, a high-impedance connection (that is, a nearly open-circuit fault such as a burned switch contact or wire joint) in the power path might still allow enough voltage/current through to register on a high-impedance digital voltmeter, but it probably can't actuate the solenoid voltmeter. For use with high ...
The Spain-Morocco interconnection includes two 400 kV lines, commissioned in 1997 and 2006 that have a combined power of 1,400 MW and consisting of seven cables: three for each circuit, plus one for reserve. [3]

A different form of short-circuit testing is done to assess the mechanical strength of the transformer windings, and their ability to withstand the high forces produced if an energized transformer experiences a short-circuit fault. Currents during such events can be several times the normal rated current.
Certain specialized circuits can also be considered power converters, such as the flyback transformer subsystem powering a CRT, generating high voltage at approximately 15 kHz. Consumer electronics usually include an AC adapter (a type of power supply ) to convert mains-voltage AC current to low-voltage DC suitable for consumption by microchips.
A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...
When line commutated converters are used, the converter station will require between 40% and 60% of its power rating as reactive power. This can be provided by banks of switched capacitors or by synchronous condensers , or if a suitable power generating station is located close to the static inverter plant, the generators in the power station.
