Maintaining electrical equipment performance in healthcare facilities, and ensuring a long service life, requires a stable electrical supply.
Bender’s new PEM735 – ‘a comprehensive class A1 power distribution network analyser’, monitors power quality in accordance with DIN EN 501602. The company explained: “Such measurement at the point of common coupling allows evaluation of the ambient conditions for electrical equipment in relation to the voltage.”
Bender says ‘power quality phenomena’ often cause failures in process installations, or premature material fatigue, adding: “Increased harmonics or irregular voltage fluctuations – so-called ‘flicker’ – can also affect electrical equipment’s expected service. With a class A power quality analyser, all relevant voltage characteristics can be monitored and evaluated.” Measurement and analysis features range from the frequency, through harmonics, to transient events and ‘flicker’.
Due to the PEM735’s high sampling rate, high frequency harmonics caused, for instance, by inverters, can be measured. If power quality ‘events’ occur, the PEM735 records high-resolution current and voltage waveforms. The data is stored locally in a 1GB capacity memory; the results are accessible via a 5.8 in colour display, fieldbus communication, or on a PC via a web server.
