Why maintain furnace transformers?

1. An electric furnace transformer is the most expensive and basic piece of equipment in a substation. Therefore, various preventive maintenance activities need to be performed to ensure that the transformer maintains a high level of performance and a long functional life.

2. We only perform some other types of maintenance on the transformer when needed, called emergency or failure transformer maintenance. However, if regular maintenance is done correctly, this will greatly reduce the chances that such emergency maintenance will need to be performed. Regular inspection and maintenance of transformers is also called condition maintenance.

3. Therefore, emergency and fault maintenance can be avoided through proper state maintenance. This is why technicians should focus primarily on state maintenance. 0% device failures due to 100% state maintenance.

How to check furnace transformer?

1. The oil level under the oil cap of the silicone respirator must be checked every other month. If the transformer oil in the cup is found to be lower than the specified level, it should be refueled according to the specified level.

2. The pores of the silicone respirator should also be checked monthly and, if necessary, properly cleaned for proper breathing movements.

3. If the transformer has an oil-filled casing, the oil level of the transformer oil inside the casing must be visually checked in the oil gauge on the casing. This is also done on a monthly basis.

4. If necessary, oil should be injected into the bushing to the correct level. Refueling in shutdown condition.

What are the signs of furnace transformer failure?

1. How do I know if the transformer on my stove needs to be replaced? If a transformer fails, it can cause a different set of problems. For example, a tripping circuit breaker may indicate a transformer failure.

2. transformers may fail by allowing too high a voltage in the furnace, or by allowing too low a voltage in the furnace. In the former case, the circuit breaker may trip. High voltage can cause the circuit breakers in your home to trip. Your stove may be turned on only to allow the circuit breaker to trip and then shut down prematurely.

3. A faulty transformer may prevent your furnace from starting. Even if you turn up the thermostat, your stove may not turn on. This usually happens when the voltage is too low. If the transformer does not allow a high enough voltage into the furnace, it may not open.

4. Your furnace transformer may have obvious signs of failure. For example, when it fails, it may have black or brown markings. These marks are usually the result of overheating of the transformer due to high voltage. If your furnace transformer overheats, you need to replace it.
