Outdoor products are essential components of medium-voltage distribution grids. Siemens' comprehensive outdoor portfolio of switching devices and vacuum circuit breakers is designed for a wide variety of applications and climatic conditions.
Waves in one part of a circuit can be transferred to other circuits by inductive and capacitive coupling. As indicated above a transformer appears to a steep-fronted wave as a distributed capacitance which can be crudely represented by a simple pi network (Fig. 9.5). From the figure, Cp and...
Voltage regulationis one of the major concerns in LVdistribution networks[30]. It is the utility׳s responsibility to keep the customers׳ service voltage within an acceptable range.Fig. 4shows an example of voltage limits for the primary circuit, the service entrance, and utilisation based on...
S11 and S13 series products are the most widely used power distribution transformers, mainly used in 10kV distribution network, with capacity range of 30-3150kva and rated voltage level of 10kV. S11 and S13 are energy-saving enterprises, among which S13 series energy-saving transformers are mad...
Servo drives come handy in a lot of applications, but controlling them and the power needed to drive them can be challenging when attempting to do it efficiently. Similarly, handling overload and short-circuit conditions is critical. Through this webinar, we will demonstrate best practices of pro...
In this circuit TR1 forms the series pass transistor. The second transistor, TR2 acts as the differential amplifier, feeding the error voltage between the reference diode and the sensed output voltage which is a proportion of the output voltage as set by the potentiometer. The r...
