The Three-Stage Model of Service Consumption is a model to
explain the consumption process when dealing with services. The
three stages involved are namely the Pre-purchase Stage, the
Service Encounter Stage and the Post-encounter Stage. In the
Service Encounter Stage, one common framework used to capture the
stage is known as the Servuction Model/Framework. State and
explain a service’s invisible and visible elements as mentioned by
the Servuction Model/Framework.
A three phase source supplies a building with 18 KV which has a
group of four 3-phase loads as follows:
LOAD 1: Wye connected; S=444 KVA and 0.84 lagging power
factor
LOAD 2: Delta connected; S=693.75 KVA and 0.64 leading power
factor
LOAD 3: Wye connected; Z= 140 + j240 Ω
LOAD 4: Unbalanced wye-connected and grounded load,
with Za = 14+j3 Ω , Zb = 5-j24Ω and Zc =1+j14 Ω
What is the current phasor flowing through each conductor?
A three-phase balanced star load No. 1 of (120 +j90) ohms in
parallel with another three-phase balanced star load No. 2 of (90
+j120) ohms, both are fed by three-phase balanced conductors of 3
ohms resistance and 4 ohms reactance. If the generator is 240
volts, with angle of -150° on phase c and reactance of 1 ohms,
determine: a) the current on load N°1 on phase C, b) the terminal
voltage of the generator on phase B, c) the...
Explain how the demand and supply model relates to the
maturation phase of the product life cycle. How will profit
incentives lead to different responses of what to produce?
A three-phase line has an impedance of 1 + j2 Ω per phase. The
line feeds two balanced three-phase loads that are connected in
parallel. The first load is Y-connected and has an impedance of
20+j40 Ω per phase. The second load is ∆-connected and has an
impedance of 30-j60 Ω per phase. The line-to-line voltage at the
load end of the line is 415V. Taking the phase voltage Va as
reference, determine: a) The total current per phase from...
