Battery systems for superior use and reliability

Facilities such as data centers, hospitals, airports, public companies, oil and gas facilities, and railways cannot function without 100 percent backup power reliability. Even standard commercial and manufacturing facilities have backup power systems for their emergency systems, alarms and controls, emergency lighting, and smoke and fire control Battery systems.

Most standby power systems use an uninterruptible power supply (UPS) and a set of batteries. The UPS serves as a backup to the Digital Control System (DCS) to maintain control of plant operations until it can be safely shut down or until the standby generator starts.

Although most batteries used in modern UPS systems are maintenance-free, they are still susceptible to deterioration from corrosion, internal shorts, sulfation, drying, and seal failure. This article establishes the recommended practices to maintain the optimal operation of these “Battery systems banks”, so that the reserve is ready in the event of a blackout.

The two main indicators of battery status

One: internal resistance of battery

Internal resistance is a test of service life, not capacity. The resistance of the battery remains considerably uniform until it approaches the end of its useful life. At that point the internal resistance increases and the battery capacity decreases. Measuring and recording this value helps to identify when the battery should be replaced.

Fluke 500 Series Battery Analyzer

Measuring Ohmic Values ​​in Sequential Mode with a Fluke 500 Series Battery Analyzer Use only a special battery tester designed to measure the resistance of the battery while it is in use. Read the voltage drop across the load current (conductance) or AC impedance. Both results are expressed in ohmic values. An isolated ohmic measurement has little value without context. Recommended practice requires the measurement of ohmic values ​​over months and years. Each measurement must be compared to previous recorded values ​​to generate a baseline.

Two: the discharge test

The discharge test is the best way to discover the actual available capacity of a Battery systems, but it can be difficult to carry out. During this test, the battery is connected to a load and discharges over a specified period of time. In addition, the current is regulated and a constant known current is established while the voltage is measured periodically. Details of the discharge current, the specified time period for the discharge test, and the battery capacity in amp-hours can be calculated and compared to the manufacturer's specifications. For example, a 12 V 100 Ah battery may require a discharge current of 12 A for eight hours. A 12 V battery is considered discharged when the terminal voltage is 10.5 V.

Batteries do not carry critical loads during a discharge test, or immediately after completion. Transfer critical loads to another Battery systems bank for a significant time after testing is complete and reconnect a temporary load, comparable in size, to the tested batteries. Also, before testing, prepare a cooling system to compensate for the rise in ambient temperature. When large batteries discharge, they emit a large amount of energy in the form of heat.

Good batteries must maintain a capacity greater than 90% of the factory ratings. Most manufacturers recommend replacing the battery if its capacity drops below 80%. When performing battery tests, look for the following fault indicators:

  • More than 10% drop in capacity compared to baseline or previous measurements
  • 20% minimum increase in impedance compared to reference or previous measurements
  • Continuous high temperatures compared to manufacturer's reference and specifications
  • Degradation in the condition of the plates

Reforms that will revalue your home in 2021

Mood reforms. Are you thinking of selling or renting your house? Or at the moment just to make it more comfortable and beautiful, without ruling out the idea of incorporating it into the real estate market in the near future? Before taking the step, remember that updating the bathrooms or the kitchen can multiply its price. How much more? Quite. The previous reform of your home can suppose a revaluation of between 10 and 20%. Little joke then! Take note of the reforms that we propose to revalue your home in 2021 and at the same time make it the most sought-after (and attractive) in the neighborhood. Why are reforms important? Knowing that the comprehensive reform of an apartment of about 90 square meters would be around € 50,000, we are going to see if it is worth the expense. Taking into account that an investment of this type guarantees a revaluation that could reach 20%. It seems logical to bet on the reform in your home. And not only that, but also 7 of the 10 second-hand h

How to maintain your motorcycle before the rainy season hits?

Motorcycle drivers should be taking precautions before the rainy season hits. If you want to avoid costly maintenance or repairs, it is important that you maintain your motorcycle in a good condition. Don't let the rain get you down - follow these tips for maintaining your bike this fall!   1. Check your motorcycle tires for wear and tear If your motorcycle tires show any signs of wear and tear, it's important to get them changed as soon as possible. If the tread on a tire is worn down too far or has multiple cuts in it that could lead to an air leak or blowout, then you need new rubber before anything else happens! 2. Clean off the bike with a damp cloth to remove any dirt or grime Cleaning the motorcycle is a good way to remove dirt and grime. This will prevent any damage being done should you come into contact with another vehicle. It's important to properly clean your bike. One way is by using a damp cloth and removing any dirt or grime that may be on it w
