Frequently asked questions

• How do I know what transformer to buy?

  You have to asses the number electrical devices, add to it the illumination and consult the company.

• What is the dehydrator filter?

  It is an accessory in transformers that have an expansion tank. It must contain silica gel (not pink). It ensures that the air that enters the interior of the machine does not contain humidity which damages the coolant.

• What is a dial thermometer?

  It is a instrument that constantly controls the temperature of the coolant. Should the temperature be inadequate, it protects the transformer.

• What is a Buchholz relay?

  It is an accessory used in power transformers in order to detect the presence of gasses dissolved in the oil as a result of hot points in the active part. In addition, it works as a level in case there is a leakage of insulating liquid.

• What kind of maintenance does a rural transformer need?

  It must be checked that is leveled without humid sectors or points that indicate leakages of insulating liquid and coolant. If there is a leakage, contact the company so as to solve the problem. Periodically, samples of the oil must be taken and then tested so as to find out if the transformer is working properly.

• What kind of maintenance does a distribution transformer need?

  The silica gel in the air dehydrator filter must be perfectly white or have blue points, which would indicate that it  is working correctly. If it is pink , it should be replaced immediately. The levels of insulating liquid and coolant must also be checked. Periodically, samples of the oil must be taken and then tested so as to find out if the transformer is working properly.

• What kind of maintenance does a power transformer need?

  indicate that it  is working correctly. If it is pink , it should be replaced immediately. The levels of insulating liquid and coolant must also be checked. The correct adjustment of the indicators of the thermometer must be reviewed . The relay Buvhholz must be inspected so as to detect the presence of  accumulated gasses. Periodically, samples of the oil must be taken and then tested so as to find out if the transformer is working properly.
