Electronic transformer has many characteristics superior to conventional transformers

Electronic transformer air circuit breaker having a lot better than the traditional features such as light weight, good linearity, easy and digital measurement and protection equipment interfaces. This paper uses a gas-insulated switchgear for the new combined current and voltage transformers, transformer by the current sensor, power transformers and the digital converter consists of three parts. The measurement is based on the coil current and voltage measurement is based on a capacitive divider. Digital converter FPGA as the core, using numerical Circuit breaker techniques to restore the measured current and voltage signals. Digital converter of the current sensor and the voltage sensor output is converted to a digital optical signal via the optical fiber to the control room.
