Power Factor
PFI Plant Panel
For a DC circuit the power is P = VI and this relationship also holds for the instantaneous power in
an AC circuit. However, the average power in an AC circuit expressed in terms of the rms voltage
and current is
Where
is the phase angle between the voltage and current the
additional term is called the power factor
LT Switchgear Panel
From the pharos diagram for AC impedance, it can be seen that the power factor is R/Z. For a
purely resistive AC circuit, R=Z and the power factor = 1.

ACB Range: 800A - 6300A
Low Voltage Dry Type Capacitor
VCB: 630A—1250A
VCB’S:
AC high voltage vacuum
circuit breaker is a type of holistic
and completely sealed HV switch
gear it has compactable dimension
and small volume. The VCB applies
to power system of rated voltage
12kV, three phase and AC 50/60Hz.
It is applicable in occasions with
frequent operations, acting to
protect and control line and electric
apparatus. The product conforms to
IEC62271, GB1984, JB3855 and
DL1403 and passes KEMA test.
This capacitor bank is installed at low
voltage (220v, 380v, 440v,) electrical
system in parallel for improving power
factor and performance of electrical
power quality.
Used advanced technology consists of
metalized PP film with extremely low
loss factor. The dielectric system is self
healing and has no liquid imp regnant.
Capacitor enclosed in cylindrical aluminum cases. The construction described
above and the uses of high quality
materials ensure reliability & longevity.
MCB Range: 2A - 63A
MCB’S: Protection and control the
circuits against overloads and Short
circuits protection for people and big
length cables.
Application: Factory, Buildings both
residential and commercial.
Operating Voltage: 230V / 440V
Surge Protective Device (SPD)
The single block multi pole modular
power type surge arresters provide
protection for equipment against
transient over voltage that occurs
on the electrical network (mains).
FLANGE MOUNTED ONLOAD
TAPCHANGERS (OLTC) - CTR
AVR Range: 3KVA – 630KVA
ACB’S: Air circuit breakers are rated
800A to 6300A, 50Hz, 380V in
voltage. The breaker is mainly used to
distribute electric energy in the power
distribution network and to prevent the
circuit and power source equipment
from overload, under voltage and short
circuit. Under the normal conditions,
the breaker can be used to switch the
circuit and start the motor infrequently.
With the current limiting characteristics, the ACB is especially suitable for
the large short circuit current is likely
to occur
INVERTER: 200V-240V single - phase
200V- 240V/380 -500V/525V to 600 V,
3 phase, 50/60 Hz. Speed regulation
by flux vector control Speed range
from 1 to 50, 2 Hz to 3 Hz without
adjustment Auto-tuning Protection of
motor and of drive Operation up to
50°C without de rating brake
sequence

Generator Set - 50Hz
MCCB Range: 16A - 1600A
MCCB’S: Protection and control of
electrical machineries against over
loads, short circuits protection for
people and big Length cables.
Applications: Industrial & residential
low voltage plants.
A.C switchgear for motor protection
generators, capacitors, cable etc.
