How to Get Solar Modules Replaced Under Warranty Claim!!
Generally, Manufacturers follow these checks to validate the replacement of the solar module. 1. Loading, Unloading and Transportation Conditions – Solar PV panels are exposed to various risks during their journey. There can be a certain amount of mechanical stress that can affect the module in the transportation process. The reasons can range anywhere from rough handling of the packed modules to vibrations or shocks that occur in the back of a truck, on a rail, or during transshipment on the sea. The most common damages to solar panels are breakages and cracks of the solar cells in the …
Compressed Air Leakages and Its Impacts!!
Compressed Air leakages Leaks can be a significant source of wasted energy in an industrial compressed air system, That can result in 20-30% wasting of a compressor’s output sometimes. If regular maintenance activities have not been followed, a possible leak rate can be equal to 20% of the total compressed air production capacity. With regular maintenance activities in a place like proactive leak detection and repair, leaks can be reduced to less than 10% of the compressor output. 1. Planned Leaks The planned air leaks are the ones that have been designed into the system. These leaks are the blowing, …
Major Location of Compressed Air Leakages!!
1. Main Supply Line and Branch Connections Two Material composites can be used for main supply lines i. Plastic Pipes Air leak inspections should focus on connection points and any bends in the pipe. Suspension hangers as these are areas of strain which, when combined with vibration will be the first area where cracking will appear. ii. Metal pipes Stronger anchoring and suspension are required as steel is heavier than plastic. Most steel pipes are uncoated which leaves them susceptible to corrosion; even if you use a good dryer system to eliminate moisture. Rusty pipes can cause damage to pneumatic …
Major Causes of Industrial Air & Gas Leakages!!
Why does an Air Leakage occur? Air leakages are one of the operating concerns of using compressed air systems. But timely leak tests and scheduled maintenance can help avoid compressed air leaks and ensure the longevity of your compressor. Here are some reasons why air leakages happen. 1. Moisture-laden air Rich in moisture content, untreated/semi-treated air may enter the air network and begin damaging the internal parts of the pipes. This can cause air leaks. Corrosion happens when semi treated air or untreated air laden with high level of moisture content and typical residual compressed air humidity of more than …
Compressed Air and Gas Leakage Detection Methodologies!!
Water Immersion Bubble Test Method This is a traditional and relatively primitive technique of leak detection. This includes immersing a charged or pressurized part, usually with high-pressure dry air or nitrogen, in a water tank and watching for escaping bubbles. The larger and more frequent the bubbles, the bigger the leakage. Limitation – Small equipment like pumps and tanks can be checked with this methodology but the equipment like vessels and storage tanks can be tested with this method standard industrial practices don’t support this as there are chances of huge investments. Soap Solution Bubble Test Instead …
Is your Field-Working staff aware of the Arc Flash hazardous areas of the manufacturing facility?
Defining arc flash boundaries is the crucial part of the Arc Flash Analysis. Depending on the potential arc flash hazard, this boundary is calculated separately based on specific system information. There are different types of boundaries as shown in the figure below. Let’s look at what the mentioned terms mean – Boundary Arc Flash: When an arc Flash hazard exists, an approach limit from an arc source at which incident energy equals 1.2 cal/cm2 (5 J/cm2 ). The flash boundary is the farthest established boundary from the energy source. If an arc flash occurred, this boundary is where …
Know Your Electrical Network Through Power System Study – Load Flow
What does load flow analysis show? Load flow analysis calculates the steady-state voltages, currents and active and reactive power flows in a defined electrical-network model. The results help engineers assess equipment loading, losses and voltage performance for the agreed operating cases. They depend on the input data, network configuration and assumptions; they do not describe every transient or fault condition. Load-flow studies are performed to determine the steady-state operation of an electric power system. It calculates the voltage profile, voltage drop on each feeder & at each bus, real power (MW/KW) & reactive power (KVAR/MVAR) power flow in all branch …
As Build Documents – Adding in Accuracy
Manufacturing facilities/infrastructure companies/waste treatment plants have been building the facilities to last long for like 15 to 20 years. Currently, we all are living in a world where we experience a change in technology more often. Earlier technology used to change in 10-15 years but in current times we can see the transformation in 3-5 years only. Then there comes the question to embrace the change to survive the competition out there. And that is possible only if you have your existing data in place. Imagine the hustle you may go through if you don’t have all the as-built documents …
