Q1. Life cycle in angular,component communication,Directives ,component
Ans. 
Angular life cycle, component communication, directives, and components are key concepts in Angular development.
• Angular life cycle includes ngOnChanges, ngOnInit, ngDoCheck, ngOnDestroy, etc.

• Component communication can be achieved using @Input, @Output, services, or event emitters.

• Directives in Angular are used to add behavior to DOM elements.

• Components are the building blocks of Angular applications, each representing...read more

Q1. What is the method for calculating the fault current of a VCB breaker?
Ans. 
Calculating fault current for a VCB involves system parameters, fault impedance, and breaker ratings.
• Identify the system voltage and configuration (e.g., three-phase, single-phase).

• Determine the source impedance (Zs) and load impedance (Zl).

• Calculate the fault impedance (Zf), which may be negligible in short-circuit conditions.

• Use the formula: Fault Current (If) = Voltage (V) / Total Impedance (Zs + Zl + Zf).

• Example: F...read more

Q2. What type of breaker do you prefer for high voltage (HV) and low tension (LT) sides along with protection features?
Ans. 
For HV, I prefer SF6 circuit breakers; for LT, MCBs or MCCBs are ideal, each with specific protection features.
• HV Side: SF6 Circuit Breakers - Excellent insulation and arc-extinguishing properties.

• LT Side: MCBs - Protect against overload and short circuits, ideal for residential applications.

• LT Side: MCCBs - Provide adjustable settings for overload protection, suitable for industrial use.

• Protection Features: Earth Faul...read more

Q3. How do you manage voltage optimization?
Ans. 
Voltage optimization involves adjusting voltage levels to improve efficiency and reduce energy consumption in electrical systems.
• Conduct a voltage audit to identify areas of over-voltage.

• Implement voltage regulation devices like transformers or capacitors.

• Use smart grid technology for real-time voltage monitoring.

• Example: Installing a voltage optimizer can reduce energy costs by 10-15%.

• Regular maintenance and monitorin
