I applied via Referral and was interviewed in Apr 2022. There were 2 interview rounds.
Transformer types include step-up, step-down, isolation, autotransformer, and instrument transformer.
Step-up transformer increases voltage while decreasing current
Step-down transformer decreases voltage while increasing current
Isolation transformer separates primary and secondary windings
Autotransformer has a single winding with multiple taps for voltage adjustment
Instrument transformer is used for measuring current or
I have worked with various control voltage applications in my previous roles.
I have experience with control voltage applications in industrial machinery and equipment.
I am familiar with troubleshooting and repairing control voltage circuits.
I have worked with PLCs and other control systems that use control voltage.
Examples of control voltage applications I have worked with include motor starters, relays, and solenoids.
Yes, cable size estimation is based on the required load and can be calculated using various formulas.
Cable size estimation is important to ensure safety and efficiency of electrical systems
The required load can be calculated by adding up the wattage of all the devices that will be connected to the cable
The cable size can then be estimated using formulas such as the voltage drop formula or the NEC ampacity tables

AC voltage changes direction periodically while DC voltage flows in one direction only.
AC voltage is used for power transmission over long distances while DC voltage is used for electronic devices.
AC voltage can be easily stepped up or down using transformers while DC voltage cannot.
AC voltage is measured in RMS (Root Mean Square) while DC voltage is measured in average value.
Examples of AC voltage sources include powe...
kWh, kVAh, kVAR, kVARh are units of energy and power. They differ in terms of their measurement and usage.
kWh is a unit of energy and is used to measure the amount of energy consumed over time
kVAh is a unit of apparent power and is used to measure the total amount of energy supplied to a system
kVAR is a unit of reactive power and is used to measure the power that is not used to perform work
kVARh is a unit of reactive e...
Kw to hp conversions
1 kW = 1.34 hp
To convert kW to hp, multiply by 1.34
To convert hp to kW, divide by 1.34
