The last % refers to the percentage of completion of your most recent project or task.
The last % is a measure of how much of the project or task has been completed.
It can be calculated by dividing the amount of work completed by the total amount of work required.
For example, if you have completed 80% of a project, your last % would be 80%.

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 ...

The capacity of a furnace refers to its heating output, typically measured in BTUs or tons.
Furnace capacity is determined by the amount of heat it can produce.
It is usually measured in BTUs (British Thermal Units) or tons.
Higher capacity furnaces can produce more heat and are suitable for larger spaces.
For example, a furnace with a capacity of 80,000 BTUs can heat a larger area compared to one with a capacity of 40,000
Drive components in CCM department are the parts that enable the motor to function properly.
Drive components include motors, gears, belts, and pulleys.
They work together to transfer power from the motor to the machine.
The components must be properly sized and aligned to ensure efficient operation.
Examples of machines that use drive components include conveyor belts, pumps, and fans.
A contractor is a person or company hired to perform a specific task or project for a client.
Contractors are often hired for construction projects, electrical work, plumbing, and other specialized tasks.
They are typically paid on a project-by-project basis, rather than receiving a salary or hourly wage.
Contractors may work independently or as part of a larger company.
They are responsible for providing their own tools, ...
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).
Rectifiers are commonly used in power supplies for electronic devices.
They can be made using diodes or other semiconductor devices.
Rectifiers are essential for many electronic devices to function properly.
Examples of rectifiers include bridge rectifiers, half-wave rectifiers, and full-wave rectifiers.
vvF is not a recognized term in the field of electrical engineering.
vvF is not a standard unit of measurement or abbreviation in the electrical field.
It is possible that the interviewer made a mistake or was testing the candidate's ability to admit when they don't know something.
The candidate could respond by politely asking for clarification or admitting that they are not familiar with the term.
