Installing advanced and forward-looking electrical systems
Hospitals and medical facilities face major challenges in managing and maintaining their power supply networks. They are under increased pressure to ensure availability of critical systems and protect their electrical infrastructure from network pollution resulting from increased use of electronic equipment, while at the same time reducing energy consumption. Mumtaz Farooqi of Bender UK explains why the installation of advanced and forward-looking electrical systems is so important.
The ‘health’ of power and voltage is rarely considered in the process of managing electrical networks on which modern medical facilities and hospitals rely so heavily. However, deployment of power quality
monitoring (PQM) and residual current monitoring (RCM) technology can improve reliability and resilience while also delivering cost savings. Power quality monitoring, residual
current monitoring, insulation monitoring (IMD) and earth fault detection (IFLS) technologies from Bender equip clinical facilities to reduce costs by identifying faults before they become a problem – avoiding unexpected downtime in critical power supplies or costly emergency maintenance. Bender’s PQM devices also act as
energy meters while checking the system quality, determining the energy consumption per cost centre. PQM can show the effects of faulty network components or interaction and
interference on the efficiency of the network. The technology safeguards the quality of electricity supply by tracking and recording fluctuations in voltage and current – providing a record that can be matched to system issues.
What is power quality? Power quality is often defined as the supply of a clean, stable, and constantly available power supply. It should ideally offer a pure sinusoidal wave form and remain within specified voltage and frequency tolerances. But in real-life that is rarely the case. The impact of complex system
interactions such as voltage fluctuation, flicker, transients, voltage sags, and harmonic distortion is felt in the form of faults and failures. In the worst cases, it can result in serious damage to equipment and systems that can lead to facilities being out of use, impacting on patient care and business profitability. Power quality monitoring enables the

Bender UK is a market leader in electrical safety for the medical and industrial sectors, and head of technical Mumtaz Farooqi is an expert in the design, development, and application of power distribution and condition monitoring technology. Hospital engineers are under
increasing pressure to manage electrical infrastructure, cut costs, reduce energy consumption, and protect the ‘quality’ of power supplies more effectively. Mitigating the detrimental effects of network pollution resulting from the wider use of electronic medical devices including CT and MRI scanners, X-ray equipment, and operating robots, is an issue of increasing importance. The ‘health’ of electrical networks on which modern medical facilities and hospitals rely must be monitored to improve reliability and resilience. Monitoring can also deliver cost savings by tracking energy usage and identifying faults before they become a problem, avoiding unexpected downtime or expensive emergency maintenance. With this in mind, Mumtaz Farooqi
explains the opportunities to remotely monitor the health of hospital power systems in real-time using digitally enabled technology and internet connectivity, fixing issues before they become critical to meet the challenge of resilient and problem-free power provision in healthcare locations.
