The percentage of carbon presence in cast iron varies from 2.1% to 6.67% depending on the type of cast iron.
Cast iron is classified into four types based on its carbon content: white, gray, ductile, and malleable.
White cast iron has the highest carbon content, ranging from 2.1% to 6.67%.
Gray cast iron has a lower carbon content, ranging from 2.5% to 4%.
Ductile cast iron has a carbon content of 3.2% to 4.1%.
Malleable ca...
Addendum is the height of the tooth above the pitch circle in a gear.
Addendum is the distance between the pitch circle and the top of the gear tooth.
It is an important parameter in gear design as it affects the strength and durability of the gear.
The addendum can be calculated using the formula addendum = module or diametral pitch.
For example, in a gear with a module of 2mm, the addendum would be 2mm.
Addendum is the op...
The least count of vernier calipers is the smallest measurement that can be accurately read on the scale.
The least count is determined by the number of divisions on the main scale and the vernier scale.
It is calculated by dividing the smallest division on the main scale by the number of divisions on the vernier scale.
For example, if the smallest division on the main scale is 0.1 mm and the vernier scale has 10 division

Composite error and ratio error are two types of errors in current transformers.
Composite error is the combination of ratio error and phase angle error in a current transformer.
Ratio error is the difference between the actual turns ratio and the specified turns ratio of a current transformer.
Phase angle error is the angular difference between the primary and secondary currents of a current transformer.
Composite error a...
An AC drive circuit diagram controls the speed of an AC motor by varying the frequency and voltage of the power supplied to it.
An AC drive consists of a rectifier, DC link, inverter, and control circuitry.
The rectifier converts AC power to DC power, which is stored in the DC link.
The inverter converts the DC power back to AC power with variable frequency and voltage.
The control circuitry adjusts the frequency and volta...
A single line diagram of a distribution system is required with proper specifications.
The diagram should show the flow of power from the source to the load
It should include all components such as transformers, switchgear, and cables
The specifications should include voltage levels, power ratings, and protection devices
The diagram should follow standard symbols and conventions
Example: A 11 kV distribution system with a 5
Dewpoint test is done in transformer to check the moisture content in the insulation oil.
Moisture in insulation oil can cause breakdown of transformer insulation
Dewpoint test helps to determine the moisture content in the oil
It is a preventive maintenance measure to avoid transformer failure
The test involves cooling a mirror until dew forms on it, and measuring the temperature at which dew forms
Power transformers are used in transmission systems to step up or down voltage, while distribution transformers are used in distribution systems to step down voltage.
Power transformers are used in high voltage transmission systems to step up or down voltage for long distance transmission.
Distribution transformers are used in low voltage distribution systems to step down voltage for local distribution.
Power transformers...
Buchholz relay is used to protect transformers from faults by detecting gas and oil flow abnormalities.
Buchholz relay is installed in the pipe connecting the transformer tank and conservator tank.
It operates based on the principle that faults in the transformer generate gases and cause oil flow disturbances.
When gas or oil flow abnormalities occur, the relay trips and sends a signal to the control panel to isolate the ...
