UPS Maintenance

services

'You've made a significant investment in providing a back-up power solution, why wouldn't you continue to invest in its successful and safe operation?'

Your UPS needs regular servicing by a professionally trained UPS Engineer. These regular maintenance inspections check the operation of the UPS and its batteries to ensure safe operation and reduced risk from critical battery failure or gradual battery degradation. In addition to preventative maintenance visits, your cover plan will guarantee availability of an engineer for rapid response to any critical failure or service alarm. We can even remotely manage your equipment and identify issues before you become aware of them. Click here for more information on our PowerVue remote monitoring service.

What's included in Your Service & Maintenance Visit?

  1. Using a calibrated multi-meter, measure the phase to phase (3 phase) and phase to neutral input voltages.
  2. Perform a complete visual inspection of the equipment, including sub-assemblies, wiring harnesses, contacts, cables and major components.
  3. Check all nuts, bolts, screws and connectors for tightness and heat discoloration.
  4. Inspect for broken, brittle, damaged or heat stressed components and cables.
  5. Clean for any foreign material and dust from internal compartments.
  6. Perform a status check of alarm circuits.
  7. Perform an operational test of the system.
  8. Install or perform Engineering Field Modifications as necessary.
  9. Return the system to normal load and verify the output voltage. Calibrate as necessary.
  10. Review system performance with customer to address any system questions.

Internal Battery Maintenance Service

  1. Check integrity of battery mounting brackets and assemblies.
  2. Visually inspect battery system for: Swelling, leaks, loose foreign objects, overheated or corroded cables and connectors, loose connections on batteries and appropriate product labels related to safety and warning hazards.
  3. Clean and neutralize cell tops as required.
  4. Verify integrity of all battery terminal connections.
  5. Measure and record total battery float voltage.
  6. Record room ambient temperature.

All visits are fully documented with a signed Service Visit Report, enabling you to keep adequate records to prove that you are correctly maintaining your business critical infrastructure

Additional UPS Services

Powertecnique offers a range of additional engineer services recommended to assist you in correctly maintaining your critical and back-up power equipment. For details of our battery testing, remote monitoring and similar services please read on.

Testing UPS Expected Performance

There are different ways to test the predicated performance of your UPS equipment. The most reliable way is to Load Bank test the entire system in combination with periodically testing the battery to determine its internal resistance. However in some instances a Load Bank may not be considered appropriate due to interruptions and perceived risk. In these instances testing the battery cell internal resistance is a cost effective and reliable way to predict the health and performance of the UPS battery. The internal resistance is closely related to its capacity and therefore this can be used to help predict performance. Continue reading to better understand which testing is right for you.

UPS Load Bank Testing

You've made a significant investment in your UPS equipment and battery that is suitable to maintain your load. It's essential that you are certain that your equipment is ready to support your power requirements should it be required. Our Load Bank service tests the whole system under controlled conditions and at a time to suit you.

services

Why Do You Need to Load Bank Test?

Our Engineer will test your complete UPS back-up power system to identify any potential issues that may occur during a power failure. By identifying these issues before your UPS is actually called upon due to a power outage, we are able to correct any potential problems and reduce future risk.

How Often Should You Load Bank Test?

Regular testing reduces your risk profile and should be part of your business continuity planning. Knowing that your UPS is fully maintained, tested and fit for purpose provides great peace of mind. We recommend a full Load Bank test is carried out regularly but only as necessary. Though load bank testing gives an accurate overview of the system and battery capacity, it should be used prudently. Over testing by discharging the battery will reduce the battery service life and the load is submitted to a higher risk for some time following a discharge (until the battery is recharged once more). Load bank tests can be arranged as part of your Service and Maintenance cover plan or as a separate agreement.

Load Bank Test Benefits

  • Powertecnique's planned Load Bank testing is by far the safest way to identify any potential points of failure and ensure that your UPS is fit for purpose
  • Testing can be arranged outside of normal business operating times to minimise disruption
  • Our Load Bank tests are fully documented and certificated to provide you with the evidence needed to prove that your equipment is fit for purpose
  • Risk and Method statements ensure compliance with all Health & Safety legislation, minimising risk to you
  • Our Engineer will test your entire system providing you with total confidence in your UPS power supply integrity

What's included in Your UPS Load Bank Test?

  • Your Load Bank test will be fully documented, providing you with the relevant evidence that your equipment is fit for purpose
  • Complete and thorough test of your UPS, battery, electrical supply, cabling, switchgear, fuses and other components
  • Efficient and safe battery discharge and test
  • Mobile AC and DC load banks of any size available, allowing testing of any installation anywhere within the UK.

Battery Resistance Testing

A UPS is only as reliable as the batteries it uses to support the load. UPS users need complete confidence that their load will be supported should there be an issue with the main supply. Predicting how a battery will perform when required to do so can be challenging. Powertecnique aims to remove this uncertainty and provide you with complete peace of mind.

services

Why Do You Need a Battery Resistance Test?

Load Bank testing will provide you with an accurate indication of how your UPS will perform in the event of a power failure. However these tests are reliant on a battery discharge and sometimes the risks associated with the UPS being incapable of supporting the full load during the time it takes for the batteries to recharge following a Load Bank test can sometimes be unacceptable. Each discharge of the battery also reduces the service life of that battery. Battery Resistance Testing looks at the internal resistance of a cell and allows us to predict its expected performance and identify any cell failure risk before issues arise. This test acts as a warning indicator of cells that have deteriorated to a point where it may compromise the integrity of your UPS system.

How Often Should You Resistance Test?

Battery Resistance Testing allows us to build up a profile of your cells predicted performance. This profile is of most use when it is monitored over time to show any significant changes and potential points of failure. With this in mind we recommend at minimum annual testing and ideally this test should begin from the time of installation to obtain the actual battery baseline data, although any starting point is better than not starting at all. This can be part of your Service and Maintenance cover plan or arranged as a separate agreement.

Battery Resistance Test Benefits

  • Powertecnique's Battery resistance testing is by far the lowest risk method to predict and reduce battery failure risk
  • Resistance Testing removes the risks associated with battery discharge and does not diminish the battery service life.
  • Testing can be carried out with the UPS in normal operation with no risk to the load or if required arranged outside of normal business operating times to minimise disruption
  • Our Resistance Tests are fully documented and certificated to provide you with the evidence needed to prove that your equipment is fit for purpose
  • Risk and Method statements ensure compliance with all Health & Safety legislation, minimising risk to you

By identifying any potential issues following resistance testing, further action can be agreed. Typically this may require the replacement of the individual cell or the string or would include testing the capacity of the individual cell or string to ascertain replacement criteria based on actual performance.
