In configurations of this kind, serial reactors are connected to the capacitors. The serial reactors detune the circuit to a frequency below the 5th (or 3rd) harmonic, which is the most significant in a harmonic-rich environment. In Europe, detuning by a factor of 3.78 times the line frequency is most common, whereas in other parts of the world, in
This guideline defines the standard tests that all electrical systems and equipment must pass prior to final acceptance by the University. These tests are in addition to acceptance tests specified by equipment manufacturers or defined in the other Design Guidelines sections.
The stated specifications and requirements, both technical and testing, are universally needed for acceptance tests on-site and commissioning of ultra-high voltage power equipment, including

Function of Capacitors and Reactors. Define the following terms: working power, non-working power, capacitive power, inductive power, power factor, and unity power factor. Describe how the relationship between working and non-working power determines the efficiency of the power produced in a T&D system. Explain how capacitor banks and shunt reactors are
connected to the capacitors. The serial reactors detune the circuit to a frequency below the 5th (or 3rd) harmonic, which is the most significant in a harmonic-rich environment. In Europe, detuning by a factor of 3.78 (7%) times the line frequency is most common, whereas in other parts of the world, in particular in Asia, a factor of 4.08 (6%) is stan-dard (Fig.1). The thinking behind this
Capacitors can be used to filter out low frequencies. For example, a capacitor in series with a sound reproduction system rids it of the 60 Hz hum. Although a capacitor is basically an open circuit, there is an rms current in a circuit with an AC voltage applied to a capacitor. This is because the voltage is continually reversing, charging and discharging the capacitor. If the
