Prolong the life of your electrical equipment by monitoring your voltage supply

In recent years a massive rise in the number of ‘non-linear loads’ – from lighting ballasts to IT equipment – has led to increased harmonic distortion of the electricity supply. This causes variations in voltage that can damage sensitive electronic equipment. Gilbert Owens of Ideal Industries explains why you should pro-actively monitor the voltage supply within your buildings, in order to protect mission-critical systems. Nominal voltage: what is it and why is it important? Your equipment is designed to handle varying voltage within a specified range, called nominal voltage. For example, a fridge-freezer might be designed to operate between 220V and 240V AC, a typical range for a nominal 230V supply. However, when voltage fluctuates outside equipment design specifications, that equipment has to work harder. In the case of the fridge-freezer, if the mains voltage goes below 220V, the circuit powering the compressor motor will run hotter, which reduces... Full Article »
