ELECTROWAVE CAPE Low Voltage Primary Current Injection Services Profile Circuit Breakers are one of the critical "safetyvalves" of electrical systems and basic maintenance procedures are essential to maintain maximum reliability. Effective circuit breaker maintenance requires wellorganized, accurate testing. Breakers are situated at the key points of electrical energy transmission and distribution systems. Their reliability has a decisive influence on the availability, safety and economic efficiency of electrical supply networks. Despite constant subjection to external influences such as dirt and fluctuations in humidity and temperature they must be able to function perfectly in the case of a fault, even if they have not been operated for some time. Should a short-circuit occur, circuit breakers must interrupt extremely high fault currents within just a few milliseconds. Initially, the reliability of newly installed breakers depends on their construction, the manufacturing quality and the type and scope of final factory inspections and tests. However, once installed on site, only regular inspections and tests can guarantee perfect functioning throughout the operational life of a breaker. Comprehensive, accurate testing also requires analytical tools and efficient reporting. It must be possible to validate test results in detail and then easily compare them with other test results. We, at Electrowave Cape provide a comprehensive and highly skilled inspection, test, commissioning and maintenance service. Our engineers and senior technicians are trained, competent and are familiar with all statutory and legal documents, (isolation certificates, permits-to-work), as required. Why Test Breakers? Some of the most important of the many reasons for testing circuit breakers are: To guard against damage to expensive equipment To prevent outages that lead to loss of income To ensure reliability of electrical supply To prevent downtime and black-outs To verify breaker performance To ensure that the breaker is in a safe condition Breakers are mechanically challenging devices that require periodic adjustments. The need for some of these adjustments can be determined visual and they can be given the attention needed without testing. However, in most cases, it will be necessary to carry out electrical testing to find out what is the cause of the out-of-tolerance conditions. Furthermore, Primary current injection testing will prove whether the circuit breakers conform to the original specifications and if they are in a safe reliable condition. Anytime, anyplace, anywhere… Electrowave Cape has a fully calibrated portable high current Megger Programma Oden AT primary current injection unit, with 3 high current modules that can be transported to your premises, ship or rig. All instruments used during the testing are calibrated and are traceable to an international standard. No need to remove breakers and ship them for testing. Breakers tested on site and in same environment as used.
