Types of Substation
Step-up substation
Step-up substation is designed with advanced technology, which can effectively transmit a high-voltage power supply to the transmission line in the substation. With the use of a transmission bus, it can reduce the loss of power as well as reduce the distance between the substation and the transmission line.
Step-down substation
The step-down substations are the main components of the overhead transmission system which is used in areas where the voltage levels vary from 69kv to 34kv. These substations are linked with load centres as there is a requirement for different voltage levels for various loads.
Switching substation
As they are situated between transmission lines, one of the main functions of these switching stations is to switch the power lines without modifying the voltages. It also isolates the failed systems and de-energizes faulted equipment, allowing the grid to run more reliably.
Outdoor substation
If you are seeking a professional and effective solution for your electrical and mechanical needs then the outdoor substation is sure to be the ideal choice for you. It is designed to meet all electrical and mechanical needs of businesses, industrial plants, commercial buildings, and homes.
Indoor substation
The indoor substation is an alternative solution to the outdoor substation. The indoor substation is mostly used in places where high-voltage residential distribution lines are not allowed. This can be done by targeting lower voltage lines to a particular area or by using a building for the installation of indoor substations.
Underground substation
Underground substations are an alternative to surface substations, and they are often the most cost-effective and time-efficient solution. Subterranean substations are typically utilised as a backup system for your home or company. The best thing about underground substations is that they don’t take up any surface area because they’re installed underground. It’s a waterproof, airtight, soundproof, and temperature-controlled device that’s perfect for cramped quarters.
Mobile substation
A mobile substation is a self-contained, movable electrical supply station used for a specific purpose. Power outlets for any type of event, such as concerts, athletic events, festivals, or trade exhibitions, are provided by these substations. They’re simple to put up and provide several hours of power per day.
Industrial substation
The industrial substation is a powerful and cost-effective solution for those who require an industrial power supply. This industrial power supply comes with a machine-like appearance and supports a wide range of applications including manufacturing, agriculture, construction, mining, and more. This bulk power distribution system comes with all the necessary accessories to ensure that you have everything you need to start enjoying this cost-effective solution.
Switchyard substation
Switchyard substation is the mediator in transmission as well as generation. It is a switch box providing an identical voltage to the nearest transmission line. Switchyard substation is used in power plants which are used for generating electricity and supplying it through transmission lines.
Benefits of Substation
Reliable power supply
Substation equipment ensures a reliable power supply by maintaining voltage levels, regulating power flows, and protecting the system from faults and overloads.
Improved efficiency
They can reduce power losses during transmission and distribution, leading to more efficient power delivery and reduced costs.
Increased capacity
The Substation equipment can increase the capacity of the electrical grid by enabling the integration of renewable energy sources and improving load management.
Enhanced safety
Substation equipment incorporates safety measures such as circuit breakers, grounding systems, and protective relays, which help prevent electrical accidents and reduce the risk of power outages.
Remote monitoring and control
It can be remotely monitored and controlled, which enables operators to quickly respond to any issues or emergencies and reduce downtime.
Scalability
They can be easily expanded or upgraded to meet the changing needs of the electrical grid and accommodate future growth.
Substation Safety – Best Practices
Securing perimeter area
Minimising safety threats from the outside environment is a key concern that needs attention. Installing metallic or non-metallic fences along the perimeter is bound to prevent incidents of trespassing, deliberate scaling, stray animals foraying into the premises, and more importantly, children gaining entry into the area. Washouts and structural damage to enclosures require prompt attention. Use of appropriate warning signs on the fencing is recommended.
Restricting or prohibiting visitor access
Substations are not intended to support visitor traffic. It is possible to prevent or reduce the possibility of accidents by either restricting or totally prohibiting visitors from entering the place. In unavoidable circumstances, visitors accompanied by experienced personnel can be allowed access, but with the necessary safety precautions and PPE.
Monitoring/ guiding vehicular traffic
It is important to monitor and guide vehicles entering a substation to ensure that there is sufficient clearance between objects on the roof of the vehicle and the overhead lines and elevated equipment within the substation. Vehicle drivers must proactively ensure safe navigation as well.
Similarly, the operations of mobile hoisting equipment and cranes also need to be supervised and controlled by substation personnel.
Prohibiting equipment storage
Substations also tend to double up as storage for equipment and other material that find use in the environment, leading to at least a couple of unwarranted risks. It not only increases footfall in the area as materials get shifted in and out of the facility, but also lures thieves on the lookout for expensive electrical components/ equipment. Not everyone entering the substation in such cases are fully aware of the dangers they are exposed to and accidents that they can accidentally trigger. Prohibiting equipment storage in substations can prevent undue accidents.
Securing battery stores
Battery storage rooms are also known to be the sources of chemical hazards, and are best secured with authorised access. While it is important to ensure the storage areas are well-ventilated, regular maintenance helps detect units that need replacements, recharging or address gas, caustic or acid leaks common in batteries.
Providing PPEs
Use of PPEs, including arc flash PPE, is mandatory when working in a substation. Flame retardant and arc-rated clothing, gloves, safety glasses, shields, face masks, hard hats, and steel-toed shoes must be an integral part of the PPE collection made available for workers.
The infrastructure on the other hand must house gas detectors, scaffoldings, and rescue equipment to assure the safety of the occupants.
