Electronic Transformers: frequency power sensor is an electronic transformer, inverter power sensor through the voltage and current signals inputted AC sampling, and then enter the second instrument samples connected by transmission system with digital cable, fiber optic, etc. digital inputs secondary instrument sampled values ??of voltage and current for computing, you can get the voltage rms, current rms, fundamental voltage and fundamental current, voltage harmonics, harmonic current, active power, fundamental power, harmonic power and other parameters. [4] transformer voltage and current transformers are divided into two categories, its main role: once the system voltage, current, and accurate transmission of information related to the secondary side of the device; the primary system of high voltage, high current converted to low-voltage (standard value) on the secondary side, a small current (standard value), so that standardized measuring device, measuring instruments and relays, high voltage transformer miniaturization Wenzhou Which is better? And reduce the insulation requirements for secondary equipment; the secondary side of the device as well as the secondary system and a system of high voltage equipment well isolated electrically, thus ensuring the role of secondary equipment and personal safety voltage transformer is : The high voltage proportional relationship is converted into a standard 100V or lower levels of high-voltage transformer secondary voltage Jiaxing Which is better? For protection, metering, instrumentation device. At the same time, the use of voltage transformers can be high voltage and electrical isolation of staff. High voltage transformer voltage transformer equipment, although the work is in accordance with the principle of electromagnetic induction, but its relationship with the electromagnetic structure of the opposite compared to the current transformer. Voltage transformer secondary circuit is a high impedance circuit Hangzhou high-voltage transformer Which is better? , The size of the secondary current is determined by the impedance of the circuit. When the secondary load impedance decreases, the secondary current is increased, so that a component of the primary current is automatically increased to meet the electromagnetic balance between the primary and secondary side. It can be said, is a voltage transformer is defined structure and use of the special transformer. Simply means that the "test element."
