Power meters are used for ensuring good power quality and uninterrupted power. This is critical in many businesses and organisations. For example, commercial and manufacturing premises, data centres and healthcare facilities need high-quality power. They also need to be proactive about ensuring they have quality power rather than dealing with the consequences of an inferior power supply. Therefore power quality meters are the ideal solution.
Meters that measure the quality of power are there to ensure that a power supply isn’t compromised. This can lead to damage to infrastructures and to electrical equipment. It can also cause productivity to decrease and business to suffer. In some cases, this can lead to extreme disruption to a business or service. If power quality fluctuates, this can result in spikes, swells or sags in voltage and interruptions can vary, lasting from a fraction of a second to a couple of seconds in some cases. This unpredictable state of affairs can occur at random times but power quality meters are there to track these problems so timely action can be taken.
Power quality meters are sophisticated proactive monitoring tools that run constantly. They run using sensors and meters and monitor electrical sensitivity. The data is then used to track and interpret the results. Also, some systems include technology that communicates any power problems to facilities staff, including important information such as the part of the system to be affected.
A power quality meter can pick up problems at the outset. At this stage, they can be easier to address. Often, damage to equipment and service disruptions can be minimised. Furthermore, a review of the recorded data also helps to pick up abnormalities such as spikes, sags, swells or even outages. Knowing about these helps to diagnose problems so that any action can be taken in a timely and planned manner. Obviously, a proactive approach is better than a complete system failure and emergency repairs, which can lead to huge costs and massive disruption.
Analysis for proactive maintenance
Analysing power quality means that a baseline can be established and used to check the performance of electrical equipment over time. Having a baseline standard to measure against makes it easier to spot performance trends. Therefore, proactive preventive maintenance programs can be put in place. Also, comparing results with a baseline provides useful information to calculate power needs in the future. Finally, purchasing new equipment and maintaining existing equipment is easier to plan and execute.
When power quality meters carry out their analysis, any particular sequence of events can be investigated to find out why it happened. In such cases, analytics and forensics can find the root cause of a problem resulting from an electrical supply anomaly. Analytics and forensics can also root out power quality problems early before they cause more serious equipment damage and premature wear and tear.
When good power quality is needed for business continuity, a power quality meter works alongside a power management system. Power management systems run at a high speed and high frequency to monitor and analyse electrical components. They monitor voltages at current, normal and emergency levels as well as frequency and power. The results can be communicated via a web interface to relay information such as alerts to anyone, anywhere.
In some cases, sophisticated power quality meters can also help with testing for compliance and reporting requirements. This can be useful, for example, to help meet fire safety standards for fire protection systems and equipment.
Finally, power quality meters improve efficiency and reliability in power infrastructures, which leads to reduced energy bills and fewer staff or occupant complaints due to unreliable power. The far-reaching benefits include improved business relations and a strong business reputation for reliability and continuity of service.
