Manufacturing Process of Electrical Power Cables
Learn how to size electrical cables for load requirements and voltage drop calculation, covering ampacity, short-circuit criteria, derating factors, and IEC standards.
Explore a stepwise 22 kV cable sizing calculation to meet short-circuit and full-load ampacity, applying derating factors to justify a 70 mm² aluminium conductor.
Demonstrates high-voltage cable sizing calculations using voltage drop, derating factors, and starting and running power factors to select cable size for motor and feeder circuits, guided by standards and tools.

3. Cable Interconnection Schedule
Explore the power triangle, with active power (kilowatts), reactive power, and apparent power. Learn how improving power factor, via capacitors, reduces current and lowers utility costs and losses.
Improve power factor by local capacitive units near loads or central capacitor banks, and choose from polypropylene, mixed dielectric, or metallized polypropylene capacitors, considering harmonics and voltage rise.
Analyze capacity sizing for electrical systems, assess harmonic distortion from nonlinear devices, and apply capacitor bank sizing with detuned reactors and filters to prevent resonance and capacitor failure.

The lecture explains vendor guidelines for DG set sizing, warning against running below 30% load, addressing continuous, prime, standby duty, and mitigating harmonics with transient reactance to limit THD.
Learn to size a transformer using an Excel-based manual calculation by summing continuous, intermittent, and standby loads with duty factors, and verify voltage regulation during largest motor inrush within 15%.
Explore battery sizing for stationary and dc loads, comparing lead-acid and nickel cadmium options, applying charging, temperature correction factors, and design margins to determine the number of cells.
The goal is to design safe and dependable processing facilities in a cost effective manner. The fact is that there are very few formal training programs that focus on design and engineering of Electrical systems of such big plants The heavy electrical industry has under its purview power generation, transmission, distribution and utilization equipment. These include turbo generators, boilers, turbines, transformers, switchgears and other allied items. These electrical equipment (transformers, switchgears, etc.) are used by almost all the sectors. Some of the major areas where these are used include power generation projects, petrochemical, refineries, chemical plants, integrated steel plants, non-ferrous metal units, etc.
