Transformer

Flexible Rogowski current sensor Coil is used to measure AC Current. The error due to the position of the measured conductor within the aperture and the error due to the proximity of the external conductor are greatly reduced using magnetic shielding techniques.

Flexible Roche coil current sensor is used to measure AC Current, especially high current.Because of its flexible characteristics, it can be used to measure the conductor current with large size (such as conductor diameter ≥3M) or irregular shape or narrow space between conductor ( for example, when the traditional clamp current probe can not measure, the flexible Rogowski coil current sensor can be used to measure conveniently.) The former is plug-in type, which is used for temporary measurement of portable instrument or current, and for on-line long-time measurement of current. It is easy to install without damaging the conductor.

Drop state transformers usually refer to transformers installed on drop fuses or related equipment that can monitor and feedback the drop state. Mainly used in rural power girds, remote suburbs and other power systems that use many drop switches. In these areas, when the line overload fuse blows or the arc tube falls, causing a power outage,the transformer can send out a signal in time to help maintenance and inspection personnel quickly located the fault point, reduce the time and the energy consumption of manual fault finding. And improve emergency repair efficiency and ensure the stability and reliability of power supply.  

BH/EMS current transformer is mainly used for cables and copper bars. It has simple structure, reasonable design and flexible application. According to the specifications of the copper bars used in the main loop, there are a variety of core aperture corresponding to the main loop. This series of products can meet the technical requirements of 0.2,  0.5, 1 and other different precision GB/T20840.1.2.

When measuring the high current of alternating current, SEN-BHP2 series current transformers need to be converted to a relatively uniform current for the convenience of secondary instrument measurement( the secondary rating of current transformers is set as 5A or 1A in China). Current transformer in the process of short circuit transition can correct the primary current, the relay protection of right action plays a decisive role, protective current transformer (TA) mainly cooperate with relay protection device, such as short circuit occurred in line failure, provide signals to cut off the fault circuit to relay device, protect the safety of the power system. Name of protective current transformer: low voltage protective current transformer Primary measuring range 200~6300A, secondary output 5A, 1A, mainly accuracy level:  5P10, 10P10, 10P20, 5P20, etc. Collect low voltage overload and short circuit signals, and use with motor protection unit.
