POWER QUALITY :
Power Quality may be defined as –
The characteristics of the supply voltage and the electrical system that affect the performance of the load.
The characteristics of the load that affect the electrical system or other loads
Value of the Voltage and other PQ parameters as a percent of the Nominal Values.
POWER QUALITY ANALYSIS :
The power quality analysis provides you with an opportunity to be aware of the quality of the electrical power being utilized by your facility. Power Quality Includes
RMS Voltages ,Wave shape, Voltage Imbalance.
RMS Currents, Imbalances
Harmonics(Voltage, Current),Predominant
Load Interactions.
Power Quality Analysis would involve collection of the data about the Voltage, Current, Power factor, KW, KVA, Harmonics (THD levels of individual harmonics can be registered) in a given time frame and then using the data collected to understand –
Variations in the Voltages across the three phases and computing the associated effects.

maxCap – Details
DESIGN
o Low Loss “WETMET” Type in rectangular Aluminium/Polyurethane Self-
o Extinguishing Casing. They are Self Healing “WETMET” with Lektrol/Gas
o filled Vacuum Impregnated, NON-PCB, internal pressure Sensitive
o Interrupter.
o They are designed by assembling individual single-phase coils, coupled in
o a delta arrangement to obtain a three-phase unit.
o The coils are produced from two films of polypropylene with zinc plating on one side:
The metal plating forms the electrode
The polypropylene film forms the insulator.
All coils are then coated under vacuum into self-extinguishing thermoset polyurethane
resin which forms the casing, providing mechanical and electrical protections.
The unique vacuum potting technique ensures that maxCap capacitors have
excellent resistance over time and much longer service life than conventional
units. It also ensures that no air or humidity remains close to the coils after coating. This design provides excellent resistance to over voltages and partial discharges. Furthermore, the unit complies fully with environmental protection
requirements (no PCB).

rt@edgetechnologies.in
INSTALLATION
The compact format simplifies installation and significantly reduces cubicle or rack costs. The casing is particularly resistant to all solvents and atmospheric agents (rain, sun, salty air, etc.).
CONNECTION
The terminal blocks are easily accessible on the top of the unit, making
maxCap capacitors particularly easy to connect
The use of socket-type terminals enables cable and eye connections to
be made directly to the unit’s various ranges.
maxCap capacitors are double-insulated or class 2 units, which do
not need earthing.
INTERNAL PROTECTION
Self-healing dielectric: this is a result of the characteristics of the metal deposit which forms the electrode and the nature of the insulating support (polypropylene film).
This special manufacturing technique avoids blowing the capacitor due to
Over voltages. The dielectric is perforated when over voltage occurs, causing discharges which vaporize the metal around the short circuit and instantaneously restore electrical insulate.
Electrical fuse: one per coil
Over pressure disconnecting device: if an electrical fault cannot be
overcome by the self-healing dielectric or the electrical fuse, gas is emitted, deforming a membrane and taking the defective coil out of the circuit.
These three protection mechanisms, associated with the under vacuum coated coils, form a highly advanced unit
DISCHARGE RESISTORS
The discharge resistors enable the unit to be discharged in compliance with applicable standards. They are fitted internally and/or externally on the connection terminals.

LOSS FACTOR
maxCap capacitors have a loss factor of less than 0.1 x 10-3. This leads to a total wattage consumption of less than 0.3 W per kvar including the discharge resistors.
CAPACITANCE
Tolerance on the capacitance value: ± 5% .The manufacturing process, which avoids any air inclusions in the coils, ensures that the capacitance remains exceptionally stable throughout the service life of the MAXCAP Capacitor.

WHY NEUTREX?
Harmonic Currents are caused by virtually any appliance or machine in a building (except resistive loads) & have various negative implications for electric utility companies and consumers.
The worst harmonic source turned out to be the personal computer and electronics equipments with a THD varying from 25% to almost 89% and a crest factor of 3.89 to 4.00. While the Displacement P.F. indicated a healthy 0.85, the total True PF figured out to be only 0.43 to 0.70.
They can interfere with other electronic and signaling equipment (mains
pollution) and cause premature failure.
Skin effect can cause overheating and efficiency losses.
Eddy current losses also cause overheating & efficiency losses.
Excessive harmonic currents in neutral conductor cause dangerous hazards
since neutrals are not always protected by circuit breakers.
Communication Interface: Magnetic coupling, between electrical power
circuit and communication circuits can cause what is known as Communication Interface in other words the RFI/EMI; current flowing in the power circuit produces a magnetic/ electrostatic field that will induce a current/ voltage in the nearby conductors of the communication circuit. The amount of interference will depend upon the magnitude of the induced current/voltage, frequency, and the efficiency of the magnetic/ electrostatic coupling. Other types of communication interfaces are.
Induced line noise.
Interference with power line carrier systems.
