Transformer power transmission system

In order to transmit electrical energy power systems, often using AC voltage, high current loop power was transferred to the user, the instrument can not be measured directly. Transformer, which is to the AC voltages and currents can be reduced in proportion to the value of direct measurement instrument to facilitate

Direct measurement instruments, Circuit breaker as well as protection and automatic device to provide power. Power system transformer is to network with high-voltage, high-current transmission of information to the low voltage, low current secondary metering, instrumentation and protection, a special variable automatic devices

Pressure device, is a liaison system and secondary system components, and its primary winding is connected to the grid, the secondary winding respectively measuring instruments, protective devices connected to each other. Transformers and measurement instrumentation and metering device with, a system can measure voltage, current and power

Energy; fit with relay protection and automatic devices that can pose a variety of faults on the grid electrical protection and automatic control. Transformer performance will directly affect the power system measurement,mcb circuit breaker  measurement accuracy and reliability of the relay protective devices.
Transformer voltage transformer and current transformer is divided into two categories, its main role: the primary system voltage, current, accurate information transmitted to the secondary side of the related equipment; would a system's high voltage, high current is converted into two The low voltage secondary side (standard value),

Small current (standard value), the measurement, measuring instruments and relays and other devices standardization, miniaturization, and reduces the need for secondary equipment insulation requirements; the secondary side of the device as well as the secondary system with a high-voltage equipment in the electrical aspects of the system are Good isolation, thus ensuring

The secondary equipment and personal safety
