CLASSIFICATION OF LT PANEL
▶ PCC--- Power Control Center.
▶ MCC- Motor Control Center.
▶ AMF- Auto Mains Failure Panel
▶ APFC- Automatic Power Factor Correction
▶ Distribution Panels.
ABOUT PCC PANEL
▶ A Power Control Centre (PCC) is a main power control panel that
contains feeder breakers and supply breakers, monitoring devices,
control devices, switching devices, protection devices, and
instrumentation devices. Alternatively, it is called the Main
Switchboard. This type of switch is mainly installed near power
sources, so its fault level is high. In order to function properly, it must
be able to satisfy 50KA or 65KA fault levels for 1 second.
▶ A Power Control Center’s bus bar system is designed to handle fault
levels and temperature rises up to 40 degrees Celsius. The
termination of cables is provided with ample space. In order to
protect the source and equipment, various protections are provided,
such as short circuits, overloads, earth faults, under voltages, etc.
ABOUT MCC PANEL
▶ A Motor Control Center (MCC) is an assembly that controls several or
all-electric motors centrally. There are multiple enclosed sections and
a common power bus. Each section has a combination starter, which
consists of a motor starter, fuses or circuit breakers, and a power
disconnect. It is also possible to equip a motor control center with
push buttons, indicator lights, variable-frequency drives,
programmable logic controllers, and metering equipment. In some
buildings, it may be combined with the electrical service entrance.
▶ Typically, Motor Control Centers can be found in large industrial or
commercial buildings containing a lot of electrical motors that must
be controlled centrally, such as an electrical room or mechanical
room.
ABOUT AMF PANEL
▶ Automatic mains failure (AMF) panels are an automated switching
device that switches the load to main or stand by generator. During
the event of main power failure, AMF automatically makes the power
switch to emergency standby generators. Without AMF panels, stand
by generators need to be operated manually and that can cause data
loss, potential damage to electrical equipment, and huge amounts of
disruption. When the mains power supply returns, the AMF panel
switch back to the mains supply and shuts down the running generator
after a suitable cooling run. Automatic mains failure panels are
sometimes also called an Automatic Transfer Switch (ATS). The AMF
panel includes a battery charger, electronic circuit boards, power
relays, and terminal blocks
ABOUT APFC PANEL
▶ APFC Panel means Automatic Power Factor Correction Panel. In some
cases, in industrial applications, the loading pattern of the entire network
will change from time to time. So if that type of Industries connect a fixed
compensation. It will not be in a position to compensate exactly what is
required for Power Factor. But, in case of APFC panels that type industry
will have a microprocessor or Micro controller based relay which helps you
to sense the load current instantaneously and the particular MC relay will
hunt for capacitors to compensate and power factor improvement will be
automatic. APFC is nothing but steps of capacitors connected to the
contactor in turn connected to the breakers and relay. It doesn’trequire
much of the manual support as of fixed compensation is concerned. Your
power factor will be improved automatically; APFC will have a step by step
compensation.
ABOUT DISTRIBUTION BOARD
▶ A distribution board (also known as panelboard, breaker
panel, electric panel, fuse box or DB box) is a component
of an electricity supply system that divides an electrical
power feed into subsidiary circuits while providing a
protective fuse or circuit breaker for each circuit in a
common enclosure. Normally, a main switch, and in recent
boards, one or more residual-current devices (RCDs) or
residual current breakers with overcurrent protection
(RCBOs) are also incorporated.
HT PANEL
▶ Definition – HT panel is a metal enclosure fitted with HT Circuit Breakers, relays
&metering that is used to receive 11KV/33KV supply (from one or more source) &
distribute the power through its outgoing feeders. Outgoing feeder may be one or more
it depends on the load of the building.
▶ HT panel is installedin substations of Commercial complexes, residential colonies,
factories, schools, hospitals etc. To receive & distribute HT supply.
▶ Main functions of HT panel –
▶
▶ To make & break HT supply (or switch on or switch off supply),
▶ To receive & distribute HT supply,
▶ To provide protection against faults,
▶ To provide metering to monitor various parameters.
FEATURES OF HT PANEL
(FOR 11KV OR 33KV)
▶ HT panel receives electrical Supply 11KV or 33KV) from H – poleby 3 core HT cable
& then it distributes power through one or more outgoing feeders.
▶ These outgoing feeders are connected with distribution transformers which
convert HT supply into 415V, 3-phase 4 wire AC supply.
▶ To measure electrical power consumption, Energy Meter is installed in it,
▶ Meters are installed to measure electrical Voltage, Current, frequency, power
factor etc.
About CRP panel
▶ A Control & Relay Panel (CRP) solution is designed to control several feeders,
through medium voltage indoor and outdoor switchgear in a primary
distribution substation.
▶ It is typically deployed when associated switchgear does not have space to
accommodate the protection, control, and monitoring needs of a substation.
▶ The CRP solution can also be extended to incorporate substation HMI, time
synchronization, metering and networking functionality in the substation and
thereby avoid requirement of a separate control room.
▶ By deploying CRP solutions also enhances the safety to the substation
engineer, as exposure to a live switchgear is mitigated.
▶ And therefore, it is designed and customized to fully suit requirements of a
particular customer site.
Testing
Generally, all the residential houses rely on the local power generating
companies for electricity. The power from the utility company is routed to the
main switchboard, which then distributes the electricity to the home’s
appliances. For example, domestic lighting, appliance and other gadgets. In
simple words, we can say an electrical panel is a metal box with a door that is
placed into a wall in a secluded area of your home.
Main breaker panels, fuse boxes, main lug panels, and subpanels are the four
types of electrical panels. The primary breaker panel in your home is the most
essential of all the panels. It regulates the circuit breakers as well as the house’s
power usage. Fuse boxes contain a large number of fuses that safeguard your
circuits from overheating. Subpanels are electrical panels that receive electricity
via a specific circuit from the main panel. They let you set limits on how much
power each member of your household uses.
Need for electrical panel testing
▶ An electrical panel test is performed in any power system to ensure that the panel
construction, connection, and performance are correct from an operational, reliability, and
safety standpoint. So to ensure the continuity of electrical operation comprehensive panel
test is performed in the factory. During commissioning and maintenance programmes with
different inspections to ensure the continuity of electrical, operations a panel test is done.
▶ Keep an electrical panel in excellent repair by following these guidelines.
▶ While performing the testing, it has to make sure that all the connections and wiring are
done in accordance with IE(Indian Electricity) rules.
▶ The cable continuity and earth resistance values must be maintained at a safe level,
according to IE requirements.
▶ The panel board must be correctly earthed.
▶ And all metal pieces must be grounded.
▶ Connections between the panel board and machines are supposed to be as short as possible.
▶ It is always better to keep them away from sunlight, wet conditions and pollution as well.
▶ To summarise, there may be various leaks or risks that might occur when dealing with
electricity. As a result, thorough testing must be performed at regular intervals to assure the
safety of the equipment and the users. Following a thorough investigation, it was discovered
that Karytron is one of the top firms offering numerous testing services.
ASSEMBLY & INSTALLATION OF ELECTRICAL
PANEL
▶ Installing an electrical panel board is a crucial task that requires precision
and adherence to safety standards. Whether you are setting up a new
electrical system or upgrading an existing one, a well-installed panel board
ensures the efficient distribution of electricity throughout a building.
▶ 1. Assessment and Planning:
▶ Before you begin the installation, conduct a thorough assessment of the
electrical needs of the building. Consider the types and number of electrical
devices that will be connected. Plan the location of the panel board, ensuring
it complies with local electrical codes and regulations.
▶ 2. Gather Necessary Tools and Materials:
▶ Gather the tools and materials required for the installation. This may include a voltage
tester, wire strippers, screws, screwdrivers, and the electrical panel board itself.
Ensure that all tools and materials are of high quality and suitable for the task.
▶ 3.Install Circuit Breakers:
▶ Carefully install the circuit breakers into the panel board. Different circuits may
require breakers of varying sizes, so refer to the electrical plan to ensure the correct
placement. Tighten the breakers securely but avoid overtightening.
▶ 4. Connect Wires:
▶ Connect the wires to the appropriate terminals on the circuit breakers. Follow the
color-coding standards to ensure proper identification of wires. Double-check
connections to prevent any loose or crossed wires.
