Isolation transformers

Электрооборудование

The selection of a suitable device is carried out taking into account the electrical load of the facility and the operating conditions. It is recommended to give preference to models of reliable companies whose products are popular in the market.

Isolation transformers

Isolation transformers are used where galvanic isolation of the primary and secondary circuits is required, as well as isolation of the connected equipment from the ground loop. The use of devices allows you to increase the level of electrical safety of the facility. Consider the features of isolation current transformers .

Construction

The main elements of transformers include:

  • magnetic system - a set of plates placed in a certain sequence. Special electrical steel is used as a structural material;
  • primary and secondary winding - copper or aluminum conductors, the length and size of the section of which depends on the performance of the model;
  • metal case - for devices that require protection from mechanical damage or other external influences due to the nature of the model's purpose.

A characteristic feature of isolation transformers is the absence of electrical connection between the windings. This constructive solution eliminates the danger associated with the possibility of unintentional touching the ground and live parts.

Application

The main functional purpose of the devices is to ensure safe operating conditions for the connected equipment at high-risk facilities. That is why the transformation ratio and similar devices are usually equal to one. The category of hazardous areas traditionally includes rooms with high humidity (bathrooms, baths and showers), as well as objects with a large number of metal structures with unstable grounding. For medical institutions, special models are produced in protective casings, equipped with an overheating protection system and a remote control for monitoring the condition of the equipment.

Characteristics and model selection

The basic operating parameters of transformers include:

  • rated power;
  • winding voltage;
  • frequency and amperage;
  • climatic modification and placement category;
  • dimensions and weight.

The selection of a suitable device is carried out taking into account the electrical load of the facility and the operating conditions. It is recommended to give preference to models of reliable companies whose products are popular in the market. In the marketplace catalog Getenergo you can buy isolation transformers from leading manufacturers of the industry on favorable terms. A wide range of products will allow you to choose a device for any enterprise. Happy choice!
