Power transmission substation safety tips

In India, the power requirement is estimated to reach 1650.59 billion units by 2023. Power substations play an important role in meeting these rising power demands. A power station is a high-voltage electrical power system that can be used to switch electrical equipment, circuits and generators. Besides, it is also used in changing the AC voltage from one level to another. It would not be wrong to say that substations are the heart of the power distribution system. It is, therefore, important to formulate guidelines that will make substations more secure against known hazards.

Here we share with you some power transmission substation safety tips:

1. Secure the area around the substation:

Minimising safety threats from outside is an important concern that needs to be paid attention to. It is better to install metallic/non-metallic fences to prevent incidents of deliberate trespassing, children gaining entry into the area and stray animals and birds foraying into the premises. Appropriate warning signs must be put on the fences.

2. Do not use the substation to store equipment:

Substations are an integral part of the electrical grid, responsible for transforming and distributing electricity. However, often they have used storage facilities for equipment and other materials. This can lead to a number of unwarranted risks, including increased foot traffic in the area as materials are shifted in and out of the facility. Not everyone who enters the substation is aware of the dangers he or she is exposed to. So it is essential to not use the substation area for storage. 

3. Make sure adequate training is provided personnel at the substation 

Training is one of the important safety practices. Safety training must ensure that personnel:

• Understand the risks that are present in the substation area
• Wear appropriate PPE such as arc flash PPE, arc-rated clothing, gloves, safety glasses, shields, face masks, hard hats, and steel-toed shoes.
• Maintaining and using each piece of equipment in a proper manner.

• Be cautious even when around de-energised equipment. Maintaining the prescribed clearance and handling operations remotely if there is an option available.

• Knowing how each function such as clearance requirements, what parts need to be energised at what voltages, levels of protection and risk involved.

• Conducting routine inspections to check the equipment and area is safe.

4. Conduct regular visual inspections:

Visual inspections are not just an important part of preventive maintenance but also safety procedures. By regularly checking for signs of wear and tear, potential problems can be identified and dealt with before they cause serious damage. The first step in a visual inspection is to ensure that the area is safe to work in. Once the area has been assessed, the next step is to look for any visible signs of abnormality or failure. If any problems are found, they should be recorded and appropriate action is taken to rectify them.

5. Make sure the vehicles have safe access to substations 

Vehicles entering substations should be properly guided by the designated personnel. They should only pass over designated crossing areas where reinforcement or steel plates are placed. There should be sufficient space so that vehicles should neither touch overhead lines nor should drive over underground cableways. 

Metal vs PVC Pipes: What's Better?

 

If you are in the process of upgrading your plumbing system, you will come across the option of using either metal or PVC piping. You may wonder what the pros and cons of each are, and what’s better suited for your needs. Here are some useful insights on metal pipes and PVC pipe of water distribution:

 

 

1.     PVC pipes are corrosion resistant: Metal pipes are prone to corrosion which not only contaminates the water but also degrades the metal pipes, shortening their lifespan. This leads to unnecessary costs in repair work and replacement.  On the other hand, PVC pipes are resistant to underground external corrosion as well as internal pipe corrosion. This makes them a good choice for transporting potable and drinking water.

 

2.     PVC pipes are leak-resistant:

One of the factors that make PVC pipes a favourite is that it requires zero metalwork for welding. Most leaks occur at the joints. Joints that are required in PVC pipes can be easily sealed with solvent cement.

 

3.     PVC pipes ensure smooth flow rate: Pipe blockage is one of the most faced problems in the sewage system which involves costly and complicated repairs. The major reason for this is the slow flow of water through the metal pipes.  When corrosion builds up in a metal pipe and it restricts water flow, it causes low water pressure and a slow flow rate. PVC pipes for water distribution have a smooth lining when compared to metal pipes. Smooth lining reduces the flow resistance and provides a better surface for the water to flow easily. The pressure is also not reduced as there is less resistance when compared to metal pipes.

 

4.     Safe for drinking water: PVC pipes for water supply are considered to be a safer option as the material does not leach into the water which often happens in the case of metal pipes. As metal pipes are prone to corrosion and the metal can get easily leached into the water. Therefore, PVC pipes are not prone to bio infections causing bacteria breeding grounds. Hence, they are better for public health.

 

5.     PVC pipes are durable: Corrosion is the major cause of shortened life of metal pipes. PVC pipes being corrosion resistant have a better lifespan and can work efficiently for up to 100 years for underground piping.

 

6.     PVC pipes are lightweight: In comparison to other metal pipes, PVC pipes have a major advantage when it comes to weight. PVC pipes are lightweight which makes them easy and cost-effective to transport over heavy metal pipes.  Being lightweight, the installer does not get hurt while installing. Even a single person can handle a large piece of PVC pipe individually with ease. PVC pipes also take less time for installation. As PVC pipes are light-weight, they are easy to transport and less labour is needed, making it a cost-effective option in comparison to metal pipes.

 

7.     PVC pipes are cost-efficient: Comparatively the total cost of ownership of PVC pipes for water distribution is less in comparison to metal pipes. The cost of installing, operating, and maintaining PVC pipes is lower than that of metal pipes. Also, during the time of installation of PVC pipes, heavy lifting equipment is not needed.
