What is the working principle of a choke?

The working principle of a choke, also known as an inductor or reactor, is based on the fundamental property of inductance. Inductance is a characteristic of an electrical circuit that opposes changes in current flow. When an electric current passes through a coil of wire, a magnetic field is generated around the coil.

What is a choke in electronics?

In electronics, a choke is an inductor used to block higher-frequency alternating currents (AC) while passing direct current (DC) and lower-frequency ACs in a circuit. A choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a doughnut-shaped ferrite bead strung on a wire.

How does a choke work?

A choke is essentially an inductor that is specifically used to filter or suppress certain frequencies in an electrical circuit. It consists of a coil of wire wound around a magnetic core, typically made of ferrite or iron. The coil creates a magnetic field when current flows through it, and this magnetic field stores energy.

How does a common mode choke work?

The working principle of a common mode choke relies on the concept of inductive reactance, which resists changes in current. When a common mode signal passes through the choke, the magnetic field generated by the choke opposes the unwanted noise.

Does a choke have a resonant capacitance?

A choke, as with any inductor, also exhibits some degree of self-capacitance or "distributed capacitance". This capacitance in conjunction with the design inductance are resonant at some particular frequency. At low frequencies this capacitance has virtually no effect and the choke could be depicted as in "A" below in Figure 1.

How does a choke voltage affect the output voltage?

So the choke voltage, and therefore the current ripple needed to induce it, is the same at all load currents. In practice an increase in load current does drop the output voltage slightly, because it has to pass through the neglected resistances of choke, rectifier and transformer.

Typically, series capacitors are applied to compensate for 25 to 75 per-cent of the inductive reactance of the transmission line. The series capacitors are exposed to a wide range of currents as depicted in Figure 1, which can result in large voltages across the capacitors.

How does a series Capaci-Tor increase transmission line loading?

The reduction of the series inductance of the transmission line by the addition of the series capaci-tor provides for increased line loading levels as well as increased stability margins. This is apparent by reviewing the basic power transfer equation for the simplified system shown in Figure 2. The power transfer equation is:

Most capacitor fuses have a maximum power frequency fault current that they can interrupt. These currents may be different for inductive and capacitively limited faults. For ungrounded or multi-series group banks, the faults are capacitive limited.

What is a high voltage capacitor fuse?

For high voltage capacitor fuses, this is generally defined as 8.3, 15.5 or 23 kV, the distribution system maximum voltages. Other voltage ratings may be available for special applications. When a capacitor fails, the energy stored in its series group of capacitors is available to dump into the combination of the failed capacitor and fuse.

What is a capacitor fuse used for?

The fuse, by its design, avoids absorbing all of the available energy on the series group. This fuse is used for capacitor banks with a large number of parallel capacitors. It can be used on applications with essentially infinite parallel stored energy, as long as sufficient back voltage can be developed to force the current to extinguish.

What is a capacitor fusing factor?

The capacitor must be able to absorb this energy with a low probability of case rupture. Fuses are usually applied with some continuous current margin. The margin is typically in the range of 1.3 to 1.65 per unit. This margin is called the fusing factor.
