Describe the types of Insulators used in Transmission and Distribution .

Insulator: An electrical insulator is a material whose internal electric charges do not flow freely, and therefore make it nearly impossible to conduct an electric current under the influence of an electric field. This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily. The property that distinguishes an insulator is its resistivity; insulators have higher resistivity than semiconductors...

What is Voltage Stabilizer & How it Works? All About Voltage Stabilizer.

Introduction to Stabilizer: The embedding of microprocessor chip technology and power electronic devices in the design of intelligent AC voltage stabilizers (or automatic voltage regulators (AVR)) led to produce high-quality, stable electric power supply in the event of significant and continuous deviation of mains voltage. As advancement to the conventional relay type voltage stabilizers, modern innovative stabilizers use high performance...

What are the Differences Between Generators and Inverters?

Differences Between Generators and Inverters: There is literally no time gap in the onset of power, once there is a power outage, in case of inverter, whereas starting a generator takes considerable time.  Inverters are soundless, whereas even silent generators make a lot of noise. Generators require a power source (kerosene, diesel or petroleum) to run, whereas an inverter charges the battery with the electricity itself. Generators...

What is a differential amplifier? Why use differential amplifiers?

Differential Amplifier: A differential amplifier is the combination of inverting and non inverting amplifier. The amplifier, which is used to amplify the voltage difference between two inputs-lines, neither of which is grounded, is called differential amplifier. This reduces the amount of noise injected into the amplifier, because any noise appearing simultaneously on both the input terminals as the amplifying circuitry rejects it being...

What is RMU (Ring Main Unit) and Its Use in Electrical Power Distribution System?

Ring Main Unit (RMU) is a 11 KV or 33 KV HT panel having 3 nos. of switches (Circuit Breakers or Isolators or LBS) that are 2 for incoming one for outgoing. It enables consumer use 2 sources of HT power in at the same metering point. It is a totally sealed, gas-insulated compact switchgear unit. RMU is to be used two incoming with mechanical or electrical interlock and one out going  to the load generally but...
