The most affected electrical components in the ESP assemble Insufficient or restricted supply of fluid to the pump inlet, causing intake cavitation. Motor runs, loud noise from the water discharge end. Excess friction or blockage in the discharge piping. The flow rate/head ratio is outside the pump's capability Here, the Atlantic team look at some of the key reasons why submersible pumps can fail . Reverse Rotation This is where the pump is wired incorrectly meaning the motor runs backwards. When this happens, very little water will be pumped but it does serious damage to the pump, polishing the impeller and leading to cavitation 1. Dry Running This is where the water level drops to a point where the pump cannot draw a decent amount of water and/or starts to create a lot of disturbance in the water. This will quickly lead to cavitation*, damaging the impeller and diffuser, and quickly destroying the pump. It also causes the seal rubbers to dry out and crack which allows water into the motor 2. Running on the Right of the Curve This is where there is less vertical head than the pump is designed to handle, which makes the pump less efficient. At an extreme this causes suction cavitation indicated by the sound of marbles being pumped and pitting around the centre of the impeller. 3. Specific Gravity Submersible pumps are not designed to deal with high levels of solids and will usually quickly fail in slurry applications. Exceeding 1.1 – 1.2 specific gravity is a no-go, this effectively constitutes a sand slurry. 4. Cable Damage This includes internal damage often unseen when the cable is jarred externally. It is vital that if a cable has been gashed or yanked that this is checked. The seal arrangement where the cable enters the pump body is a weak spot and the air seal can very easily be broken. Even a few drops of moisture can make the pump fail. 5. Dead Head This is where the pump has more vertical head than it is designed for, i.e. a valve on the discharge has been closed. This causes something called discharge cavitation which is indicated by the sound of marbles being pumped, and pitting around the impeller tips and inside of the pump casing. At an extreme this can make the pump shaft break. 6. Not allowing for Discharge Piping Discharge piping creates friction loss and it is vital that this calculation is taken in to account when specifying submersible pumps. Otherwise it will lead to dead heading, see above. Cavitation - this is the formation and accumulation of bubbles around a pump impeller. This tends to form in liquids of any viscosity as they are being transported through and around a pump system. it creates a high energy shock The circular ripples which are created in this process are similar to cavitation bubbles exploding. The difference here is that due to the sheer number of bubbles creating these shock waves, the impeller and other pump components can be eroded over time.

Preventing Water Intrusion in Electrical Disconnects: A Critical Safety Measure Water intrusion in an electrical disconnect can lead to significant safety hazards and operational failures. When disconnects are not properly stored o a construction site before installation, they become vulnerable to moisture, which can seep into the enclosure. This moisture can cause corrosion of internal components, compromising their integrity and leading to potential electrical shorts or malfunction. If water is present when the disconnect is energized, it can create a path for electricity to follow, resulting in dangerous arcing or even electrical fires. Additionally, water can degrade insulation materials, increasing the risk of electrical faults. The presence of moisture also accelerates the aging process of components, reducing the lifespan of the disconnect. To avoid these issues, electrical disconnects must be stored in dry, well-protected environments until they are ready for installation. Proper storage practices, such as keeping them in their original packaging are essential. Failing to do so not only jeopardizes the safety of the electrical system but also increases the likelihood of costly repairs. Therefore, ensuring that disconnects are stored correctly is critical to maintaining the reliability and safety of electrical installations.

Cleaning the distribution panel, also known as an electrical panel or breaker box, is important for several reasons: Safety: Dust and debris can accumulate inside the distribution panel, potentially causing electrical arcing or short circuits. Regular cleaning reduces the risk of electrical faults and fire hazards. Reliability: Clean contacts and components ensure reliable electrical connections. Dust and dirt can interfere with the proper functioning of breakers and switches, leading to malfunctions or failures. Efficiency: A clean distribution panel operates more efficiently. Heat dissipation is improved when vents and components are free from obstruction, which can prolong the lifespan of electrical components. Accessibility: Regular cleaning makes it easier to inspect and maintain the distribution panel. This is important for electricians or maintenance personnel who need clear access to diagnose issues or perform routine checks. Compliance: In some jurisdictions or industries, regular maintenance, including cleaning of electrical panels, may be required to comply with safety regulations and standards. Visual Inspection: Cleaning the distribution panel allows for a visual inspection of components. This can help identify signs of wear, corrosion, or other issues that may require attention before they escalate into more serious problems. Overall, cleaning the distribution panel is a preventive maintenance measure that enhances safety, reliability, and efficiency of electrical systems in homes, buildings, and industrial facilities.

Why do we use stone/gravel in electrical Substations? Stones are used in electrical substations to provide a stable and reliable base for the equipment, as well as to improve drainage and reduce the risk of vegetation growth around the equipment. Here are some reasons why stones are preferred over sand, soil, or grass: 1 Stability: Stones are more stable than sand or soil, which can shift and settle over time due to changes in moisture levels and temperature. A stable base is important for maintaining the alignment and support of the equipment, especially in areas with high winds or seismic activity. 2 Drainage: Stones provide better drainage than soil, which can become saturated with water and cause equipment to sink or shift. Proper drainage helps to prevent water from accumulating around the equipment, which can lead to corrosion, short circuits, and other damage. 3 Fire safety: Stones do not burn, unlike grass or other vegetation, which can pose a fire hazard if allowed to grow too close to the equipment. Using stones around the equipment helps to reduce the risk of fire and improve safety. 4 Maintenance: Stones require less maintenance than grass or other vegetation, which can grow quickly and require frequent trimming or removal. Stones can be easily cleaned and inspected for damage, and any necessary repairs or replacements can be made quickly. Overall, the use of stones in electrical substations helps to ensure the safety, reliability, and longevity of the equipment, as well as to comply with industry standards and regulations. #electricalpower #nationalgrid #abb #generalelectric #schneider #siemes

What are the reasons for the presence of gravel around electrical transformers? . Gravel is used around electrical transformers for several reasons related to safety and efficiency, the most important of which is electrical insulation, as gravel does not conduct electricity, which reduces the risk of electrical conduction in the event of a current leak or damage to the equipment, and reduces humidity, as gravel helps drain water and prevent moisture from accumulating around transformers, which protects electrical equipment from damage caused by humidity, and also prevents weeds and plants, because the presence of gravel limits the growth of weeds and plants that may affect the safety of transformers, as plants may cause fires or hinder maintenance operations. Gravel also absorbs the heat generated by transformers, which helps maintain a stable temperature around the equipment, and provides stability, as gravel provides a flat and stable surface for installing transformers and protecting them from corrosion due to environmental factors, in addition to draining oil, as when an oil leak occurs from the transformer, gravel contributes to draining the oil towards the designated basin for collecting it and acts as a layer resistant to the spread of fires.
