Electricity is only of third-rate interest to hospitals. Their core business is the welfare of its patients, for which medical appliances are required, which, on their turn, require electricity. That said, electricity is a vital utility and any malfunction or interruption can easily lead to disastrous consequences.
Energy prices are high and expected to rise. All CO2 emissions are being scrutinized by regulators as well as by public opinion. As a result, energy management has become a key factor in almost every business. To get the most out of each kilowatt-hour, appliances must be carefully evaluated for their energy efficiency.
Nuisance tripping of circuit breakers is a common problem in many commercial and industrial installations. This Application Note explains the need to use true RMS measurement instruments when troubleshooting and analyzing the performance of a power system.
Capacitor banks have been used for many years to compensate the fundamental reactive power required by resistive-inductive loads. They are essential for an economic operation of the electrical system. However, non-linear loads are becoming predominant in today’s electricity system.
Safety equipment and safety circuits in commercial buildings are likely to stop functioning in the event of a fire, even if they are designed and installed according to state-of-the-art methods and regulations applicable today. This is the result of the increased resistance at the temperature at which these circuits are required to function, concludes a case study of an existing modern shopping mall in Tarnovia, Poland. The study was conducted by WTW Power Solutions.
Electric current is used for two very different purposes: the transmission of energy and the transmission of information.Although the methods and equipment used differ significantly, the same underlying properties of electric current are utilised. Information can be transmitted using voltages and currents via an electric conductor or ‘wirelessly’ via electromagnetic fields.
