panels are an integral part of the system that controls various pieces of equipment, as they provide power, operator devices, and proper control over the machinery/appliances.
Every company has its own rules and regulations when selecting control panels. It is determined by the combination of devices that must attach to it that determines the selection process as well as the outcome.
Here are a few primary components listed by control panel manufacturers.
Control Relays
Control relays have a coil that can be energized or de-energized by an electrical voltage. The contact changes the logic state by changing the coil state. There are many types of relays, but the most basic is the Timing relays. These relays are used to control contractors and pilot lights. These can be used to turn them on or off at specific times. With their built-in timers, you can justify their work.
- One-Shot Timer: The coil stays on the right state when it is energized due to the contacts.
- On Timer – These are used to switch the contact state from off to on after the delay is over when the coil is energized.
- Timer Off – The coil’s de-energized state is used to set timers to cause the contacts to switch to the off state.
- Repeat Cycle Timer – The state of the contacts keeps switching between on and off when the coil is energized.
Programmable Logic Controls
There are many components in the programmable logic controllers, such as timers and relays. They are used to transmit digital signals and input signals to the MCC panel to allow the motor to turn on. This control panel operates on the principle that the relay logic or DCS/PLC programs are used. To ensure safety regulations are maintained, labels are placed on the interlocks since all instruments and equipment are connected to this control panel. It is now possible to install a single panel rather than separate MCC or control panels thanks to technological advancements.
Motor Control Center
Indian control panel manufacturers can now customize the various control panels required by different industries. A motor control center (MCC), is basically a collection of enclosed panels that are fabricated and have a common power bus. It also contains motor control units. These panels are equipped with motor control units, blowers, and feeders. They can also be switched from manual to auto mode. These feeders are designed to meet the motor ratings. An external signal, which passes through the control panel, is needed to start the motor in the automatic provision. Motor control can include programmable controllers and frequency drives for any industry. Metering and the electrical service entry are also possible.
Low Tension Panels
These panels can be used to control high tension currents, but they are not designed to handle it. These panels are designed to withstand extreme weather conditions and high temperatures. The panel is also energy-efficient and cost-efficient, as it doesn’t consume more.
Automated Power Factor Control Panels
The APFC panels can be used when energy efficiency is a priority. Their design is flexible enough to handle voltage and power supply fluctuations and still maintain a high power factor. A unit’s electrical load will depend on the type of machinery and other devices used in the industry. The machines can be damaged if there is even the slightest fluctuation. For fixed loads, capacitors are used to protect the equipment. However, for variable loads, capacitors with a switch-in and switch-out mechanism are used.
High Tension Panels
High tension panels can contain and transfer high voltages. They are more insulation than control panels made by some electrical panel manufacturers. The electrical distribution board distributes power from the generator to various distribution boards and electronic devices. Depending on the use of electricity and their requirements, these panels are used by industries.
Synchronizing Panel
The synchronizing panel works between power sources, such as DG sets, to manage the power supply for the machinery. To eliminate any subdividing of the total load, these DG sets can be manipulated so that they act as one unit. When servicing is required for any unit, the load shall be transferred to another unit equipped with synchronizing panels units so that it can shut off. The critical load is not interrupted, so production interruptions can be avoided. As the load increases, more units can be synced and can be disengaged with low loads.
Power Control Center
The power control center, or PCC, is a common control panel which controls and monitors predetermined electrical parameters. It is made up of several vertical sections. This panel can handle high current flows at low voltage. The PCC is basically a power distribution unit that supplies power for transformers, motors, and panels that are part of electrical control systems. These panels are made of strong materials and are rigidly constructed.
Variable Frequency Drive Control Panel
The industry control panel guide states that VFD controls panels are used to protect VFDs and other electrical equipment from dust, humidity or heat. All components for different types of equipment are contained in one panel. The VFD can reduce harmonic distortion by between 3% and 5% using line reactors or harmonic filters. The bypass feature allows the VFD to continue working even if it fails. These panels are weatherproof and waterproof. The panel doors have a frequency control potentiometer that transmits command signals to the motor as requested by the operator.
Panel for Auto Main Failure
AMF (also known as Automat Transfer Switch (ATS), panels) is used to turn to emergency generators in the event of an unexpected loss of power. This allows the industry to continue uninterrupted. The mains supply is switched to the UPS (Uninterruptible Power Supply), system between the generators and the utility mains. There are many sensors on the AMF panels that can determine the type and extent of loss. It can determine if the loss is complete or partial and also note variations in the utility mains supply. If all three phases fail simultaneously, the utility mains failure covers the failure of one phase.
The control panels mentioned above can be used to handle many types of equipment and serve a variety of purposes. You can customize the metal box to fit your needs. It can hold multiple electrical devices.
According to the control panel manufacturers, there are many components that make up an electrical panel enclosure.
- Surge Arrester
- Main Circuit Breaker
- Transformer
- 24-Volt Power Supply
- Terminal Block
- Contactors and Relays
… and many other things.
Although control panels come in many sizes, most are equipped with the same devices.
