The Physics of Armature-Reaction
The Physics of Armature-Reaction

... IEEE STD 100 defines Armature-Reaction as, “The magnetomotive force due to armature winding current.” Seems rather sparse! Karapetoff‟s definition in 1911 was, “When carrying loads armature-current being a source of mmf (magneto-motive-force), modifies the flux created by the field-coils, thus influ ...

... The Aalborg – Aarhus line was energized for the first time in 2004 and in order to monitor such a ”hybrid” and at that time unknown constellation did not ”misbehave”, transient recorders were used to monitor switch‐on and  switch‐off events. And I remember Elmers comment on the latter of the above m ...

... When a heavy load is applied to the output of the AAT4608, the load current is limited to the value of ILIM determined by RSET (see Figure 1). Since the load is demanding more current than ILIM, the voltage at the output drops. This causes the AAT4608 to dissipate a larger than normal quantity of po ...

Islanding

Islanding refers to the condition in which a distributed generator (DG) continues to power a location even though electrical grid power from the electric utility is no longer present. Islanding can be dangerous to utility workers, who may not realize that a circuit is still powered, and it may prevent automatic re-connection of devices. For that reason, distributed generators must detect islanding and immediately stop producing power; this is referred to as anti-islanding.The common example of islanding is a grid supply line that has solar panels attached to it. In the case of a blackout, the solar panels will continue to deliver power as long as irradiance is sufficient. In this case, the supply line becomes an ""island"" with power surrounded by a ""sea"" of unpowered lines. For this reason, solar inverters that are designed to supply power to the grid are generally required to have some sort of automatic anti-islanding circuitry in them.In intentional islanding, the generator disconnects from the grid, and forces the distributed generator to power the local circuit. This is often used as a power backup system for buildings that normally sell their excess power to the grid.
