Voltage transformer and CT polarity
In the power system, the role of the current transformer is to change the large current into the small current, isolate the secondary loop connected to the relay and measuring instrument from the high voltage system of the primary current, and convert the primary current to the secondary current value of 5A or 1A standards.
In order to ensure the safe and economical operation of the power system, the operation of the power equipment must be monitored and measured.
Testing and Quality Control
Oswell maintains the continuous effectiveness of the quality system through annual audits, continuously improves and avoids making the same mistakes, good continuous training methods, strict technological processes, throughout the daily management of all aspects.
Features ● Output standard DC voltage ● Power-taking CT open-close structure, easy to install and operate ● The power conversion device is fixed with screws, which is easy to install ● Reserved for external energy storage device port
Also known as CTs, current transformers are devices that measure alternating current. They are widely used to measure high magnitude currents. A current transformer essentially lowers (steps down) a high current to a lower, safer level that you can manage properly. It steps down the current to be measured so that you can measure it with an average range ammeter.
High Precision Current Transformer
● low price ● Various sizes ● Asymmetrical PCB mounting mode ● Single-turn through-core primary winding application ● Applied to occasions requiring high precision and small phase error ● Applied to high-precision measuring devices for current, power and electric energy
Core column type: The primary coil is a copper column installed in the wall-penetrating magnetic sleeve, and the wall-penetrating The magnetic sleeve is the main connection between the primary coil and the secondary coil and the primary coil to the ground.
Parameters of double coil relays

Three Phase Magnetic Latching Relay
3 groups of 120A contact switching capability Contact on-off detection auxiliary switch can be provided Coil control single and double coil optional
When choosing a relay with QC lead-out method, please do not use soldering to connect the load lead-out end of the relay. If other welding methods are used, it is also necessary to ensure that the heat generated by welding will not affect the function of the magnetic latching relay
