Testing, Diagnostics and Monitoring of High Voltage Plant and

IntroductionSwitchgear MonitoringCondition Assessment of CablesTransformer TestingFailuresConclusionDuring recent years the owners and operators of electrical networks have become increasingly interested in condition monitoring of high voltage electrical equipment. Major benefits have been obtained through preventing failures, reducing maintenance, reducing operating costs and, ultimately, extending plant life. The use of testing, diagnostics and condition monitoring systems has enabled assessment of the condition of existing distribution equipment by using a number of applied techniques during routine inspection, maintenance, or during initial commissioning phases. It has also been recognised that simply increasing the frequency of maintenance can have a negative effect and increase failure rates. The provision for gathering information on the condition of the assets has given key personnel the ability to make informed decisions and ensure the effective operation of the electrical distribution network. There are a number of characteristics that give information about a piece of h...Get price

Switchgear - Wikipedia

High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on the low-voltage side of the transformers may be located in a building, with medium-voltage circuit breakers for distribution circuits, along withGet price

Maintenance RequirementsPreparation Before MaintenanceMaintenance ProcedureSwitchgear SparesLubrication of Operating MechanismsTroubleshooting GuideMaintenance covers a wide range of activities, all of which are required to keep the switchgear in ready condition at all times to enable it perform its functions satisfactorily. The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance.
