InaTech FM Global Solution Interview Questions, Process, and Tips

A single line diagram for HT to LT panel diagram is a simplified representation of the electrical system.

• The diagram shows the flow of electricity from the high voltage side to the low voltage side.

• It includes all the major components such as transformers, switchgear, and distribution panels.

• The diagram also shows the protective devices such as fuses and circuit breakers.

• The single line diagram is used for planning, de...read more

DOL starter is a type of motor starter that directly connects the motor to the power supply.

• DOL stands for Direct-On-Line

• It is the simplest and most common type of motor starter

• It is used for small motors with low starting current

• It provides full voltage to the motor during starting

• It does not provide any protection against overloading or short circuits

Load calculation can be done by measuring the power consumed by the load and dividing it by the voltage supplied.

• Measure the power consumed by the load using a wattmeter

• Divide the power by the voltage supplied to get the load in amperes

• Use the formula P=VI to calculate the power consumed by the load

• Consider the power factor of the load while calculating the load

The number of circuit breakers used in an electrical system depends on the size and complexity of the system.

• The number of circuit breakers can range from a few to hundreds or even thousands depending on the size of the electrical system.

• Circuit breakers are used to protect electrical equipment from damage caused by overloading or short circuits.

• The type of circuit breaker used depends on the specific application and t...read more
