What is magneto optical current transformer?
What is magneto optical current transformer?
Magneto Optic Current Transformer is a device in which electromagnetic waves propagate through a medium that has been altered by the presence of very slowly changing reversible magnetic field.
How optical current transformer works?
Main Features. Trench optical current transformers are based on Faraday effect principle. The output is a low power optical signal which is then transferred to a merging unit which adapts it to communication protocols such as IEC 61850-9-2.
What is optical voltage transformer?
Optical Current Transformers and Optical Voltage Transformers, based on the Faraday and Pockels effect, are a new family of instrument transformers and an alternative to the conventional electric-magnetic transformers for protection and metering purposes.
What is an optical transformer?
Optical Current Transformer is an alternative to the existing conventional current transformers, providing an advanced measurement solution for both metering and protection applications, based on a cutting-edge patented optical sensing technology.
What is the function of current transformer?
A current transformer is a device used to produce an alternating current in its secondary, which is proportional to the AC current in its primary. This is primarily used when a current or voltage is too high to measure directly.
How does a transformer work?
A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. When voltage is introduced to one coil, called the primary, it magnetizes the iron core. A voltage is then induced in the other coil, called the secondary or output coil.
What is optical voltage sensor?
Optical effects used for voltage sensing usually include electro-optic Pockels and Kerr effects, electro-gyration effect, elasto-optical effect, and electroluminescent effects, etc. In principle, typical optical voltage sensor is based on electro-optic Pockels crystals and closed-loop signal detection scheme.
What is PT function?
The primary physical therapy practitioner is the Physical Therapist (PT) who is trained and licensed to examine, evaluate, diagnose and treat impairment, functional limitations, and disabilities in patients or clients.
What is the main purpose of current?
Current is one of the most important and fundamental elements within electrical and electronic technology. The current flowing in a circuit can be used in a variety of ways from generating heat to causing circuits to switch, or information to be stored in an integrated circuit.
