Power fluctuations are one of the most important factors that can disrupt the performance of electrical equipment, electrical panels, industrial machinery, control systems, and sensitive equipment. A sudden increase or decrease in voltage, frequent disconnection and connection of electricity and creation of momentary overvoltages can, in addition to reducing the life of equipment, stop work processes and impose heavy repair and replacement costs. For this reason, installation and commissioning of protection equipment against power fluctuations is considered one of the important measures to increase the safety and stability of electrical systems.
smart power technical and engineering group is ready to provide a suitable solution to deal with fluctuations and electrical disturbances according to the conditions of each project by providing specialized services in the field of industrial electrical systems, switchboards, protective equipment, automation and electrical control and protection solutions. The correct selection of equipment, the basic design of the protection circuit and the implementation of the standard are three important factors in the correct operation of the protection system.
Why are power surges dangerous for equipment?
Electrical equipment needs a certain range of voltage and power quality to work properly. When the voltage goes out of the allowed range, the operation of the device may also suffer. Power fluctuations in simple equipment may only reduce the life of parts, but in industrial equipment and sensitive systems, it can have more serious consequences.
For example, electric motors, drives, PLCs, instrumentation equipment, lighting systems, network equipment and control panels are sensitive to inappropriate voltage changes. Repetition of this situation can cause heat increase, incorrect operation, burning of parts and production line stoppage.
For this reason installation and operation of protective equipment against power fluctuations should be considered as part of the power system design, not as a side action after a problem occurs.
What is the use of protective equipment against electrical fluctuations?
Protective devices are used to control, limit or interrupt current and voltage in abnormal conditions. The type of equipment required depends on factors such as the type of consumer, system power, voltage level, network type, environmental conditions and the level of sensitivity of the equipment.
In a professional project, it is not possible to prescribe a specific protective equipment for all systems. First, the network condition and consumer needs should be checked and then the most suitable equipment should be selected.
Among the most important protective equipment and solutions, the following can be mentioned:
- Voltage protectors
- Voltage and phase control relays
- Overvoltage protection equipment
- Surge protection or SPD
- Protection switches
- Suitable fuses
- Phase control equipment
- Stabilizer in required applications
- UPS for sensitive equipment
- Motor protection equipment
- System Proper earthing
- Protective equipment inside the electrical panel
Each of these equipments has a specific task and their correct selection and installation is very important.
The importance of installing and operating protective equipment against electrical fluctuations
Simply purchasing protective equipment cannot guarantee the safety of the electrical system. Even a high-quality equipment, if it is not selected according to the network or is installed incorrectly, it may not perform as expected.
Installation and commissioning of protection equipment against electrical fluctuations must be done based on technical principles. In this process, the equipment installation location, current capacity, voltage level, wiring method, upstream and downstream protection and coordination of different equipment are important.
Also, in some projects, the protection system must be coordinated with the electrical panel and the control system of the complex. This issue is especially important in factories, workshops, greenhouses and industrial complexes.
Steps of installing and setting up protection equipment against electricity fluctuations
Initial survey of the power grid
The first step is to check the state of the complex's electrical system. At this stage, things like the type of network, whether it is single-phase or three-phase, power consumption, type of loads, sensitive equipment and observed problems are checked.
If the set is facing shutdown, voltage drop, voltage increase or frequent disconnection and connection, it is very important to know the cause of the problem before choosing the equipment.
Identification of sensitive equipment
Not all consumers have the same sensitivity. An industrial motor, PLC, lighting system and electronic equipment may require different protection methods.
In installation and commissioning of protection equipment against power fluctuations, sensitive equipment should be identified and prioritized so that protection can be designed according to the importance of each consumer.
Choosing the right equipment
After checking the network, protective equipment is selected. The choice should be made based on technical specifications, rated current, voltage level, type of load and working conditions.
Using inappropriate equipment may cause unnecessary outages or even lack of protection. Therefore, expert advice before purchasing equipment can prevent additional costs.
Protection circuit design
In industrial projects, the placement of protective equipment is very important. The circuit should be designed in such a way that in abnormal conditions, it can isolate the desired part from the network and prevent the transmission of the problem to other parts.
Proper design also makes system maintenance easier in the future.
Implementation of wiring and installation of equipment
In the execution stage, the equipment is installed in the panel or in a suitable place and the wiring is done according to the plan. Observance of safety principles, use of appropriate cable, firmness of connections and proper separation of circuits are important issues at this stage.
Installation and commissioning of protection equipment against electrical fluctuations must be done by experts; Because the smallest error in wiring or choosing the right path can affect the performance of the system.
Testing and commissioning
After installation, the performance of the equipment is checked. At this stage, it should be determined how the protective equipment works in different conditions and whether their settings are suitable for the system or not.
Correct testing before project delivery can identify many possible defects.
Protection of electrical panel against fluctuations
The electrical panel is one of the most important parts of any electrical system and contains various equipment such as switches, contactors, relays, PLC, terminals and control equipment.
Exposing the board to fluctuations and overvoltage can disrupt the performance of the equipment inside the board. For this reason, it is very important to use appropriate protective equipment in the design of the panel.
The technical and engineering group of smart power can consider suitable protection solutions in the construction or modification of electrical panels by examining the needs of the project.
The role of SPD in the protection of electrical equipment
SPD or Surge Protective Device is one of the important equipment for protection against transient overvoltages. These equipments can direct the overvoltage energy to the right path and protect the downstream equipments under certain conditions.
Choosing the right SPD depends on the type of system, installation location, level of protection required and project conditions. Also, the proper performance of SPD is directly related to the correct design of the earth system.
Therefore, in installation and commissioning of protection equipment against electrical fluctuations, the selection of a piece of equipment should not be checked separately; Rather, the protection, wiring and earthing set should be coordinated.
The importance of earthing in the protection system
Earth system is one of the basic parts of electrical protection. The presence of proper earthing can help the proper functioning of some protective equipment and provide a suitable path for the discharge of unwanted currents.
Weakness in the earthing system may reduce the performance of protective equipment. For this reason, checking the condition of the earth should be considered in electrical protection projects.
In industrial projects, in addition to increasing safety, proper earthing also helps to better protect control and electronic equipment.
Protection of industrial equipment against electrical fluctuations
Industrial machinery usually consists of a set of mechanical, electrical and electronic equipment. Motor, contactor, inverter, PLC, sensor, HMI and other control equipment may react to power quality problems.
In this situation, installing and setting up protective equipment against power fluctuations can be one of the solutions to reduce the risk of damage to the equipment and unwanted stoppage of the process.
In industries, protection is not limited to only one device; Rather, the entire electricity chain should be examined from the input of the complex to the sensitive consumers.
The role of Smart Power in the implementation of protection systems
smart power technical and engineering group, focusing on technical and electrical engineering services, can be with the client in the field of examining project needs, designing solutions, choosing equipment, implementing installation and commissioning of protection systems.
One of the advantages of the specialized implementation of these services is the simultaneous attention to the protective equipment and the overall structure of the electrical system. This makes the final solution not only focused on buying a protector and the real conditions of the project are also considered.
Smart Power can review and implement services related to industrial power systems, switchboards, control, protection, PLC, cable trays, earthing and solutions related to electrical infrastructure according to the needs of the project.
What sets require protective equipment?
Almost any set that uses electrical equipment can require some form of protection against electrical problems. However, the sensitivity of this issue is greater in industrial environments and collections for which it is costly to stop the equipment.
Factories, production workshops, greenhouses, office buildings, commercial centers, industrial facilities, production lines, complexes with automation equipment and control systems are among the places where the correct design of electrical protection is very important.
How to reduce costs caused by electricity fluctuations?
Damage to electrical equipment is not always limited to complete burning of a device. Reducing the life of parts, frequent breakdowns, stopping production, losing information, increasing the cost of repairs and reducing productivity can also be the result of electrical problems.
For this reason, the cost paid for the installation and commissioning of protection equipment against power fluctuations can be part of a preventive approach to reduce the risk of equipment failure in many projects.
In order to achieve the right result, it is better to check the network condition by an expert first, instead of buying protective equipment without technical examination.
Why is the specialized implementation of protective equipment important?
Choosing the right brand is only one of the success factors of a protection system. Correct capacity, installation location, settings, wiring, equipment coordination and network conditions all affect final performance.
Professional execution makes the equipment to be selected and installed according to the actual structure of the project. Also, if the future development of the system is needed, the protective structure can be designed from the beginning with the ability to expand.
