Transformers are used to change current and voltage values without the need to change the frequency values. Generally, transformers are used for stepping up and down the current and voltage values. Another use of transformers is to distribute electrical energy. This way, the aim of transformers is to ensure energy flow between circuits. The maintenance of current-voltage transformers, which are essentially the brain of electrical systems, needs to be done regularly according to certain regulations and guidelines. Therefore, maintenance should be done in compliance with these guidelines. Regular maintenance is essential. Otherwise, there will be constant malfunctions, which can cause power outages in the area. Maintenance of current-voltage transformers should be done by professionals who specialize in this field. It is recommended that current-voltage transformer maintenance be performed at least once a year. During maintenance, the current and voltage transformers should be disconnected from the electrical point. At the same time, phases should be checked one by one using a high-voltage control pen. Environmental precautions must be taken during current-voltage transformer maintenance.

How to Perform Current-Voltage Transformer Maintenance?

In order to perform regular current-voltage transformer maintenance, experts in this field are required. Maintenance begins by cleaning the connections at the input and output. Then, the oil inside the transformer needs to be checked for suitability. The grounding system of the transformer is cleaned and checked. The cables that provide current and voltage inside the transformer are checked during maintenance. The most important maintenance step for transformers is to check for oil leaks. The paint on the outside of the transformer is checked, and any areas that need to be painted are painted. There are certain points called "star points" inside transformers where the grounding is checked. During current-voltage transformer maintenance, the fans used for cooling inside the transformer are checked. If there is any dirt on the outside of the transformer, it is cleaned with water. The heads of cables that cannot be wiped by hand are wiped with thinner. Signals are sent to check the operation of the transformer. The status of the energy flow of the system is controlled with these signals.
