• Star/Delta Type( Vector Group) 
• Impedance/PF/Efficiency/Voltage Level 
• Mounting-Pole/Base
Transformer Calculations 
Transformer sizing 
Total Connected load = 185.85 kW 
Max. demand = 185.85 x 0.9(load factor) 
= 167.27 
Transformer Cap. = 167.27/(pf x eff ) 
=167.27/(0.85x0.85) 
=231.51 kVA 
Considering 85% loading of Xmer = 231.51/0.8 
=271.36 kVA 
Nearest available higher capacity 315 kVA
Diesel Generator(DG Set) 
A. Categorize into 
1. Continues load 
2. Non continues load 
3. Intermediate load 
B. Selection Consideration
Diesel Generator 
• Selection Consideration 
• Capacity Combination 
• Load pattern & DG set capacity-Overlaod 
a) 10% overload for 1hour of every 12 hours 
b) 50% overload for 15 seconds. 
Technical Comparison for DG set

Illumination 
• Illuminance is a measure of how 
much luminous flux is spread over a given 
area. One can think of luminous flux 
(measured in lumens) as a measure of the 
total "amount" of visible light present, and the 
illuminance as a measure of the intensity of 
illumination on a surface 
Building Services-Electrical 21
Lux Level 
• The lux (symbol: lx) is the SI unit of illuminance and luminous 
emittance, measuring luminous flux per unit area. It is equal 
to one lumen per square metre. 
• Lux Level 
Moonless Sky/Dark overcast night- 0.001 Lux 
Moonless clear night sky – 0.002 Lux 
Full moon – 0.27-1 Lux 
Street Light – 39 Lux (Avg) 
Living room – 250 Lux 
Office – 350-400 Lux 
Day light/Sun light – 10000-25000 Lux 
Building Services-Electrical 22
Light Fixture 
• Luminaire = Lighting fixture 
– Lamps 
– Lamp sockets 
– Ballasts 
– Reflective material 
– Lenses, refractors, louvers 
– Housing 
• Mounting- Ceiling, Recessed, Surface, Flush, 
Concealed 
Building Services-Electrical 23
Fixture Types 
• Incandescent 
• Fluorescent 
• CFL(Compact Fluorescent Light) 
• Light Emitting Diode 
• High Intensity Discharge 
Building Services-Electrical 24
Types of Lighting Controls 
– Occupancy Sensors 
– Bi-level Switching 
– Time Clock 
– Photo Sensors 
– Dimmers 
– Lighting Control Systems 
– Building Management Systems 
Building Services-Electrical 25
Color Temperature (K˚) 
• A measure of the “warmth” or “coolness” of a light source. 
– ≤ 3200K = “warm” or red side of spectrum 
– ≥ 4000K = “cool” or blue side of spectrum 
– 3500K = “neutral” 
– 5000K = “Daylight”

  • 21. Illumination • Illuminance is a measure of how much luminous flux is spread over a given area. One can think of luminous flux (measured in lumens) as a measure of the total "amount" of visible light present, and the illuminance as a measure of the intensity of illumination on a surface Building Services-Electrical 21
  • 22. Lux Level • The lux (symbol: lx) is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square metre. • Lux Level Moonless Sky/Dark overcast night- 0.001 Lux Moonless clear night sky – 0.002 Lux Full moon – 0.27-1 Lux Street Light – 39 Lux (Avg) Living room – 250 Lux Office – 350-400 Lux Day light/Sun light – 10000-25000 Lux Building Services-Electrical 22
  • 23. Light Fixture • Luminaire = Lighting fixture – Lamps – Lamp sockets – Ballasts – Reflective material – Lenses, refractors, louvers – Housing • Mounting- Ceiling, Recessed, Surface, Flush, Concealed Building Services-Electrical 23
  • 24. Fixture Types • Incandescent • Fluorescent • CFL(Compact Fluorescent Light) • Light Emitting Diode • High Intensity Discharge Building Services-Electrical 24
  • 25. Types of Lighting Controls – Occupancy Sensors – Bi-level Switching – Time Clock – Photo Sensors – Dimmers – Lighting Control Systems – Building Management Systems Building Services-Electrical 25
  • 26. Color Temperature (K˚) • A measure of the “warmth” or “coolness” of a light source. – ≤ 3200K = “warm” or red side of spectrum – ≥ 4000K = “cool” or blue side of spectrum – 3500K = “neutral” – 5000K = “Daylight” Building Services-Electrical 26
