What is substation maintenance?
A well planned electrical substation maintenance assures reliable supply and reduction in failures. The electrical substation maintenance involves periodic planned inspections, checking, testing and troubleshooting, to ensure the correct operation of all components and their interaction during the plant lifecycle.
What are the different types of maintenance carried out in substation?
The substation maintenance includes periodic electrical testing of different parameters of the transformer, being common the checking of some key magnitudes such as turns ratio, excitation current, polarization index, insulation resistance, winding resistance, short circuit impedance, etc.
What is preventive maintenance in substation?
Preventive Maintenance (PM) system consists of a routine maintenance action taken in a planned pattern based on the average breakdown rates of the system components or equipment [1]. They are actions taken to improve the condition of equipment for optimal performance and prevent unintended failure or breakdown.
What is the function of a mini substation?
As mentioned, miniature substations are used to step down high voltages to distribution levels for electrical distribution. But they can be used to step up (increase) low voltages as well for transmission levels.
How do I maintain my substation?
Substation Maintenance: Six Strategies to Boost Productivity and Safety
- Pay close attention to one-line diagrams.
- Focus on battery maintenance.
- Practice continuous testing of components within a substation.
- Use manufacturer specifications.
- Shine a spotlight on safety.
- Watch out for co-worker complacency.
What does a switchyard do?
A switchyard is that place where a number of High Voltage switches are installed. Switchyards passes power through them and can interrupt the flow of power manually or under fault condition. Generally switchyards do not have any transformer.
What are the 4 levels of maintenance?
Four general types of maintenance philosophies can be identified, namely corrective, preventive, risk-based and condition-based maintenance.
What is electrical substation maintenance?
The electrical substation maintenance involves periodic planned inspections, checking, testing and troubleshooting, to ensure the correct operation of all components and their interaction during the plant lifecycle.

How much land area is required for a GIS substation?
The land area required for a GIS substation is in the order of 10% to 20% of that for an AIS substation considering the switchgear bay. The saving in overall land area depends very much on the specific voltage level and the connection to transformers, reactors and incoming and outgoing lines.
