Eight major equipment in the substation

Equipment used in substation Bus bar: bus bar is a very important component of the substation because it is the common conductor for incoming and outgaining lines. Hence any fault taking place on the bus bar will

Classification of amplifiers according

Voltage amplifier: it is the amplified where only the signal voltage is amplified i.e. input and outputs are in terms of voltage only. Current amplifier: it is an amplifier where only signal currents are amplified. I.e. input

Methods of coupling

Resistance-capacitance (RC) coupling It is also known as capacitive coupling amplifier using this coupling are known as RC coupled amplifier the function RC coupling network is two-fold: To pass a signal from one to next To block

Necessity of coupling

Whenever large amplifier with very good impedance matching is required, a signal stage amplifier circuit will not able to amplify the signal to a large extent. Thus, a number of stages are required for amplification, for this

What is an indicator?

An indicator is a substance that undergoes a change when the endpoint of a titration is reached E.g.: acid indicators are used to single the end of acid-base titration. Indicators are organic weak acids or bases with

Application of astable multivibrator

The astable multivibrator is used as the wave generator. It is used as voltage-frequency converter. It is used in pulse synchronization. Since it produces square waves, it is a source of production of a harmonic frequency of

Explain the frequency stability of an oscillator

Manos table multivibrator has one stable state and one quasi-state. It is also known as one-shot multivibrator or univibrator. It remains in its stable state an input pulse triggers it into its quasi-stable state for a time

Differentiate between single-walled carbon nano-tube and multi-walled carbon nano-tube

The difference between the single-walled carbon nanotube and multi-walled carbon nano-tube are as follows- Single-walled carbon nano-tube Multi-walled carbon nano-tube SWNT is made up by rolling a graphene sheet into a seamless cylinder. MWNT is made up

Difference between feeder and distributer

Feeder Distributor In the substance (s), the voltage magnitude is reduced to a utilization level and then the eclectic power is a distribution to the various area through the conductors which is known as feeders. The distributor

Comparison of A.C distribution with D.C distribution

A.C distribution D.C. distribution 3 phase A.C distribution system requires 4 wires. D.C distribution system requires only one wire with the ground as a return path. The voltage at the far end is a less i.e. voltage
