To design busbar for increased fault level but same current rating, increase the cross-sectional area of the busbar.
Increase the thickness of the busbar
Increase the width of the busbar
Use materials with higher conductivity
Use busbar supports with higher short-circuit strength
Consider the temperature rise of the busbar
Perform a fault level calculation to determine the required cross-sectional area
The bending radius for HT cables varies depending on the cable type and size.
The bending radius for XLPE cables is typically 12 times the cable diameter.
For PILC cables, the bending radius is usually 20 times the cable diameter.
The bending radius for EPR cables is generally 10 times the cable diameter.
It is important to follow the manufacturer's recommendations for bending radius to avoid damaging the cable.
Bending rad...

Lighting levels for indoor and outdoor areas are determined based on the purpose of the space and the activities that take place.
Indoor lighting levels are typically measured in foot-candles or lux
Outdoor lighting levels are typically measured in lumens per square meter
Calculation procedures involve determining the required illuminance level for the space and selecting appropriate light fixtures and bulbs
Factors such a...
Cable glands are used to secure and seal cables in various applications based on the area of installation.
Cable glands are used in hazardous areas to prevent the entry of flammable gases and liquids.
In outdoor applications, cable glands are used to protect cables from moisture and dust.
In industrial settings, cable glands are used to secure cables and prevent them from being pulled out.
Different types of cable glands a...

I applied via Company Website and was interviewed in Apr 2023. There were 2 interview rounds.
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.
It is named after Georg Simon Ohm, a German physicist who first formulated this law.
This law is applicable to all types of circuits, including DC and AC circuits.
It is use...

PCB stands for Printed Circuit Board, a board made of non-conductive material with conductive tracks for electronic components.
PCB is used to mechanically support and electrically connect electronic components using conductive pathways.
It is made of non-conductive material like fiberglass, with copper tracks to connect components.
PCBs can be single-sided, double-sided, or multi-layered depending on the complexity of th...
Active components require a power source to operate, while passive components do not.
Active components require an external power source to function, such as transistors and integrated circuits.
Passive components do not require an external power source, such as resistors and capacitors.
Active components can control the flow of electricity, while passive components simply store or dissipate energy.
Examples of active comp...
Resistance is the opposition to the flow of current in a circuit, while a capacitor stores and releases electrical energy.
Resistance limits the flow of current, while a capacitor stores and releases charge.
Resistance is measured in ohms, while capacitance is measured in farads.
Examples of resistors include carbon film resistors, while examples of capacitors include ceramic capacitors.
Resistance dissipates energy in the...
SMT stands for Surface Mount Technology, a method of electronic component assembly where components are mounted directly onto the surface of a printed circuit board (PCB).
SMT components are smaller and lighter than through-hole components, allowing for higher component density on PCBs.
SMT components are typically mounted using solder paste and reflow soldering techniques.
SMT technology allows for automated assembly pro...
