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 ...

Different types of loads applied on long and short steel columns
Long columns are more susceptible to buckling under compressive loads
Short columns are more susceptible to crushing under compressive loads
Long columns are more likely to experience bending under lateral loads
Short columns are more likely to experience shear under lateral loads
Examples of loads include dead load, live load, wind load, seismic load, etc.
