What is the maintenance of the substation?
The maintenance of the substation is the process of periodic, planned checks and, if necessary, repair and replace all switchboards, buildings and auxiliary equipment in the installations. To put it simply, the maintenance of the substation is a regime of regular preventive checks and actions carried out to ensure that the wiring is maintained in good operating condition. This process usually consists of a number of strict visual and physical inspections and actions performed according to the set plan. The replacement of the device can be a standard procedure or only after detection of wear, damage or non -standard operation. All inspections and events during maintenance of the substation should be precisely documented and stored for the next link.
The wiring is the most critical part of any electrical power grid. Failure of one piece of distribution device can cause a total grid collapse that can take or even longer. For this reason, the care of the substation is one of the most important part of the preventive maintenance of any electricdepartment. These plans generally consist of a graded plan of small and main maintenance events. Small maintenance will rarely require any type of power shutdown, although the main events usually require short supply interruption interruptions.
routine or lower maintenance of the substation is usually performed on a weekly or bi-week basis. It usually consists only of visual inspections and surface cleaning. Inspections would include visual confirmation of the general condition of the switchboard, grounding mechanisms, transformers, liquid insulating levels and flash arrest. General control of the system's performance can also be performed using any software installed or checking the incoming and outgoing values of the meter. These checks are generally implemented in accordance with the specified checklist and all findings are recorded and file.
Main maintenance of the substation involves multiple planning and je generally processed quarterly. In the case of industrial installations, these procedures are often performed during plant maintenance. Residential wiring is slightly more difficult to plan and generally require switching to auxiliary equipment during the process. During these maintenance events, a more detailed checklist that requires check and testing the individual substation components is observed. This will usually require the insulation of individual circuit breakers and checking the reaging mechanisms, overcurrent and the protection of the Earth's leak and the integrity of the contact.
corresponding devices such as AMP and Volt meters, control circuits and transformers will also be paid to individual attention during this review. Insulating fluids such as transformer and circuit breaker oil are also checked for contaminants, dielectric decay values and dissolved gas content. In the advertisement, there are leading cable tanks and trenches, as well as the sections of the bus bar in the distribution and all the screw connections checked SPWound torque setting. It will also take place for all circuit breakers and cables during insulation resistance of 500 or 1,000 V. All main maintenance work and inspection are recorded and administered for information.
