FAQ

A: Oil pumps, air fans, along with other items that are used to cool down a transformer and control circuit must be inspected annually. Ensure to clean all the bushings of your electrical transformer with only soft cotton. Oil conditions should be carefully examined on a yearly basis.

A: This single phase pad mount transformer is found in residential or small commercial areas. They convert electricity from 7200 volts to 120/240 volts. A typical transformer this size feeds 10-15 homes or one or more small commercial businesses.

A: Some of the advantages of single phase pad mounted transformers include reduced installation costs, lower maintenance requirements, improved aesthetics, increased safety, and flexibility in space utilization.

A: Combustible structures like houses, garages, and other buildings must be at least 10 feet from single phase pad mounted transformers. For non-combustible structures, this clearance can be reduced to three feet.

A: When the use of the crane is restricted, the single phase pad mounted transformer can be moved using a rolling device. During the movement, the transformer should be kept in a vertical state and moved horizontally.

A: Like most electricity distribution equipment, single phase pad mounted transformers don't last forever and need replacing. Residential single phase pad mounted transformers have an expected life span of about 30 years, but factors such as weather and salt can shorten it.

A: Single phase pad mounted transformers are used with underground electric power distribution lines at service drops to step down the primary voltage on the line to the lower secondary voltage supplied to utility customers. A single phase pad mounted transformer may serve one large building or many homes.

A: The voltage ratio of the primary coil to the secondary coil of the transformer is related to the ratio of the number of turns of the primary coil to the secondary coil, which can be expressed by the following formula: primary coil voltage/secondary coil voltage = primary coil turns/secondary coil turns. This means that the more turns, the higher the voltage. Therefore, it can be seen that if the secondary coil is less than the primary coil, it is a step-down transformer. On the contrary, it is a step-up transformer.

A: The transformer components are mainly composed of iron core and coil, in addition to oil tank, oil pillow, insulating bushing and tap changer, etc.

A: Transformers can pose a fire risk due to electrical faults or overheating. Familiarize yourself with fire safety protocols. Have appropriate fire extinguishers readily available. Regularly inspect transformer oil levels and temperature and report any irregularities to prevent potential fire hazards.

A: These two devices work based on Faraday's law of electromagnetic induction principle. The "Generators" generate current, and transformers convert between current and voltage.

A: The most common use is for changing the voltage from 240volts down to 110 volts, or up from 110 volts to 240 volts. A voltage transformer allows an appliance designed to be run on one type of voltage to be used on another, for example, designed to be used on 110v can be used on a 240v.
