Preventive Maintenance
Key Elements of Substation O&M
Visual Inspection
Current transformers are normally filled with oil and have oil impregnated paper insulation for both primary and secondary winding. Careful inspection is to be made for any trace of oil leakages. Oil leakages are more prone through cemented joints or secondary terminal box due to improper sealing of terminal studs.
Visual inspection is also to be carried out on the healthiness of terminal connections, condition of porcelain, development of cracks, chippings, cleanliness of insulator surface, etc.
Maintenance of Gaskets
Marshaling boxes and CT terminal boxes must be sealed properly to ensure that any dust, rainwater, or insects are not able to enter the compartment. It is essential that door gaskets be replaced periodically to maintain a high level of sealing efficiency.
Furthermore, it is vitally important that all door bolts and latches are securely tightened and never left in a state of looseness. Doing so will ensure the highest level of security at all times, while also preserving the integrity of the door itself.
Secondary Terminal Connections
Stud type terminals are preferred in Marshalling box cable terminals. This gives better grip even if more than one wire is connected to one terminal. But pin type terminals are also provided in some cases. Since tightness of wires may become loose due to vibration, climatic condition, it is required to check tightness of terminals periodically to avoid maloperation / non-operation due to improper contacts.
All terminals of unused CT secondary terminals are to be properly shorted to avoid development of abnormal voltage and subsequent failure of CTs. The tan δ test tap is to be properly earthed to avoid damage to insulation
Primary Terminals
Thermovision scanning can help to quickly and accurately indicate proper connection of the primary terminal. If thermovision is not carried out, a more thorough approach of physical checking of terminal connections should be conducted with the appropriate torque specifications followed.
Furthermore, all required corona shields should be carefully installed to provide maximum protection from electrical disturbances.
Any malfunctioning or damaged corona shields should be immediately replaced with new ones to guarantee the best possible performance.
How does a 33, 66, 132 or 220 kV Substation Work?
A substation is a crucial component of an electrical power system, facilitating the transmission and distribution of electricity. It converts high-voltage power from generators to lower voltage levels suitable for distribution. Step-up transformers increase the voltage for long-distance transmission, while step-down transformers lower it for distribution.
Transmission lines equipped with protective devices deliver the high-voltage electricity to the substation. Inside the substation, switchgear and distribution equipment control and direct the flow of electricity. The stepped-down electricity is then distributed through a network of lines to end consumers. Overall, the substation ensures efficient and safe power transmission and distribution.

Visual Inspection
The most of the CVTs are not visible from outside. CTs/CVTs and CC are also oil filled equipment’s and . If oil leak is observed in anyone stack, the entire CVT is to be replaced. CVTs are tuned units and replacement of anyone stack is not recommended to phase angle errors.
Electro-Magnetic Unit
Electro-Magnetic Unit (EMU) of CVT houses the secondary transformer, Compensating reactor and . The colour of oil indicated through the gauge: glass gives some indication of the healthiness of the internal components.
Secondary Voltage
Deviation in secondary Voltage of CVT is . Necessary action to be taken to replace CVT if secondary voltage in anyone CVT is abnormal (may be +2V and -4V). Continuing the equipment in service beyond this stage may lead to failure/bursting of CVTs.
Other Maintenance
Maintenance of marshalling box gaskets, tightening of secondary terminal connections and tightening of primary terminal connections, etc., are also to be ensured for healthy operation. It is to be ensured that all extra holes at Marshalling boxes are properly plugged and kept vermin proof.
Let's make our world a better place by developing and providing access to sustainable and dependable energy sources.
