- Make sure that you clean all the bushings of your electrical transformer with only soft cotton cloth annually.
- Oil condition of OLTC should be carefully examined on an annual basis.
- Make sure to clean out the inside of all of the marshalling boxes annually.
Why is maintenance important in a transformer?
A power transformer maintenance and testing program includes the following benefits: Increased safety, problems are detected before they are a hazard. Increased equipment efficiency, conditions related to transformer losses can be corrected. Reduced expenses, repair work can be properly scheduled.
What is the maintenance of transformer?
Transformer Maintenance on a Half Yearly Basis Your electrical transformer needs to be checked every 6 months for IFT, DDA, flash point, sludge content, acidity, water content and dielectric strength along with how resistant it is to transformer oil.
What is preventive maintenance of transformer?
The preventive maintenance involves schedule maintenance and regular testing. Predictive maintenance involves extra monitoring and testing, whereas corrective maintenance considers repairing and restoring transformer integrity to its original condition when degraded conditions are found.
How do you inspect a transformer?
The transformer will be cleaned and inspected for any component damage. A visual inspection will be made for signs of overheating and for voltage creeping over insulation surfaces. Operational checks on transformer auxiliary devices will also be performed. PowerCom will examine and test for oil and /or nitrogen leaks.
What are the basic steps of transformer maintenance?
Transformer preventative maintenance involves routine inspection, adjustment, testing, minor fixes, and special handling instructions. Also, the trouble- free service of the equipment over its life depends on proper installation, operation, and maintenance. This philosophy is based on reactionary operation mode.
What are you going to do to check the continuity of a transformer?
- Step 1: Unplug The Transformer. First, unplug the transformer entirely. Set the multimeter to read resistance in ohms (Ω) afterward.
- Step 2: Check The Multimeter. Check the reading by touching the meter.
- Step 3: Repeat The Test. Repeat the test on the output leads.
What are the classification of transformers?
According to the supply used, the transformers are mainly classified as Single phase and three phase transformers. A normal transformer is a single phase transformer. It has a primary and a secondary winding and it is operated to either decrease or increase the secondary voltage.
What are the 5 applications of transformer?
- Applications of transformers.
- Regulating alternating current.
- Stopping and starting the flow of electricity.
- Battery charging.
- Steel manufacturing.
- Electrochemicals.
What are the classifications of transformers according to their construction?
Depending upon the type of construction used, the transformers are classified into two categories viz.: (i) Core type, and (ii) Shell type. Depending upon the type of service, in the field of power system, they are classified as: (i) Power transformers, and (ii) Distribution transformers.
