In addition to Autistic''s correct answer, the value of C9 (X rated) is a compromise between consuming excessive AC current at 60 Hz while suppressing the noise voltage spikes by about 3 dB to 6 dB at the …
What is the purpose of putting a capacitor on the primary side of a ...
In addition to Autistic''s correct answer, the value of C9 (X rated) is a compromise between consuming excessive AC current at 60 Hz while suppressing the noise voltage spikes by about 3 dB to 6 dB at the transformer primary if power is cut off when the 60 Hz sine wave is at or close to peak current. C9 does NOT behave like a MOV or …

I a audio DAC output stage I have seen the following circuit. It''s function is to convert an balanced signal to an unbalanced signal. IN+ and IN- are differential outputs that are biased at 2.5V. simulate this …
Capacitors (Part 1)
Okay, we''re in Section 7.3 and we''re looking at the subject of Capacitors. Capacitors are another fundamental building block in electronic circuits. Certain characteristics of a capacitor are similar to resistors and inductors. In other ways, they are unique. …
Capacitor Bank
Power system operation involves many switching functions that may inject currents with different harmonic resonance frequencies. Mitigation of such harmonic sources is vital. There is no safe rule to avoid such resonant currents, but resonances above 1000 Hz will probably not cause problems except interference with telephone circuits.. This means the …

When voltage transformer is not 1/1 ratio, this condition can be represented by energizing the equivalent circuit with an ideal transformer of the given ratio but having no losses.. Voltage transformers behave similar to small power transformers, with difference only in details of design that control ratio accuracy over the specified …
Capacitive Voltage Transformer : Working & Its …
So as to decrease the installation cost, the CVT type of transformers is used in the place of a normal voltage transformer. Starting from the range of 73 kV and more, these capacitive voltage transformers can be used …
Transformers (Part 1)
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer''s core, which induces a varying electromotive force (EMF) across any other coils wound around the same core. Electrical energy can be t…
