Why should open current transformers be chosen for power transformation projects?

   As the country and various enterprises attach importance to energy management, government buildings, corporate factories, and office buildings that have been built everywhere have begun to deploy and install energy management systems. Power consumption occupies a large proportion of all energy consumption, so power consumption monitoring plays an important role in energy consumption management.

   Electricity consumption monitoring is generally used in cooperation with electric energy meters and transformers. In the renovation project, it is recommended to use rail-type electric energy meters for convenient equipment. For current transformers, open current transformers are preferred.

The open current transformer is mainly used in the transformation projects of the urban and rural power grids in the industry. The equipment is convenient, and there is no need to dismantle the busbar once, and it can also be operated with electricity. It does not affect the customer’s normal electricity consumption. It saves manpower, material resources, financial resources and increases the rate . This series of current transformers can be used in conjunction with relay maintenance, measurement and metering equipment.

   1. Before opening the current transformer equipment, connect its secondary to the electric meter (or other measuring equipment) to ensure that the secondary transformer is not open;

   2. Put all the open current transformers connected to the secondary line on site and wait for the equipment;

  3. If the primary bus on the site is a cable, live equipment can be carried out; if the primary bus is a copper bar, the operator requires a relatively high level of proficiency and insulation protection measures;

  4. When equipment transformers are installed, no foreign matter such as impurities or dust should fall into the cut surface of the iron core to avoid affecting the transformer function.
