For this it is needed to implement modern techniques when monitoring an important element of power system, such as power transformer.
Additionally, these encompass a vast array of equipment such as machines, power transformers, capacitor banks, power electronic devices, motors, etc. that are continuously evolving in their demand characteristics.
SVC PLUS® uses standard components, such as typical AC power transformers, reactors, capacitors, and industrial class IGBTs that are widely used for traction and industrial drives.
These new transformers are named as power electronic transformer (PET) or solid state transformer (SST).
Leaning on Sony's ES heritage, the model incorporates audiophile-grade discrete components such as twin R-Core power transformers and gold-plated outputs to maintain the utmost performance.
This device uses a set of power electronic-based switches, usually made up of two antiparallel thyristors which replace the mechanical switches used in the regulation windings of conventional power transformers, as shown in Fig. 11.
Wind parks are made up of a large number of saturable inductances (power transformers, inductive voltage transformers (IVTs)), as well as capacitors (cables, wind turbine harmonic filters, capacitor voltage transformers (CVTs), voltage grading capacitors in circuit-breakers).
As a matter of fact, power transformers were largely responsible for the great development of the current AC systems, instead of the primitive DC-based ones.
In practice, the online condition monitoring of power transformers, such as dissolved gas analysis, is discrete (periodical) while the state transition could happen at any time [20, 21].
