Transients, spikes, surges …. these disturbances are the most destructive, costly and common power quality events in industry today. In the United States, these events represent billions of dollars a month in maintenance and production costs due to equipment failures, lost profits and losses due to opportunity costs. Over the years as virtually all equipment has become increasingly microprocessor based, such failures are more recurrent and more costly.
Other events such as fluctuation, blackouts and harmonics cause significant problems that are without a doubt disruptive, however are compared to transients, are much lower in actual damages.
Transients are able to stop equipment and plants for extended periods of time, causing disruptions in the processes, delays in deliveries and loss of credibility to clientele. Often, the repair costs are minimal compared to the cost of lost profits or deferred production. Equipment downtime prevents delivery on product demand and services that customers require.
A transient is a brief but powerful high-voltage and high-current event that can last up to 100 microseconds (As defined by the ANSI/IEEE C62-41). It can climb as high as 100,000 volts during extreme events such as lightning, as high as 10,000 volts due to utility substation operations/grid switching events (external sources), as high as 6,000 volts for switching inductive loads (electric motors), and as small yet disruptive as 2,000 volts created internally. These internal causes can account for more than a million events per hour in heavy industrial environments.
It is critical to invest in protection systems in order to mitigate the damages causes by transients. The investment in SINETAMER® products will cut annual maintenance electrical and/or electronic costs and provide the benefit of Return on Investment that typically ranges from 3 – 18 months. Remember that this damages can occur at any time and in a various ways: during a thunderstorm, a failure in the electrical system, in a blackout or even by a curious squirrel stumbling into an electrical transformer.
