AET and AET-C Measuring transducers

Multifunction measuring transducers for measuring electrical parameters of three-phase circuits

Technological documents on AET

Description

AET series transducers are intended for measuring electrical parameters of thee-wired and four-wired three-phase circuits. Measured values are transduced into coded output signal and transmitted to upper-level of automated control system. If real time clock (RTC) option is equipped, measured values would be transmitted with time stamps included.

Depending on version of the transducer, data is transmitted via two independent RS-485 interfaces or via one RS-485 and Ethernet.

There are versions additionaly equipped with external current sensors. Versions equipped with custom power supplies are available by custom order.

 

Example of application

 

Measured parameters (depending on version)

  • Line voltage
  • Line-to-line voltage
  • Phase current (RMS value)
  • Frequency
  • Active power (overall and for each phase separately)
  • Reactive power (overall and for each phase separately)
  • Apparent power (overall and for each phase seperately)
  • Power factor (overall and for each phase separately)
  • Displacement power factor (overall and for each phase separately)
  • Many more parameters are calculated

Supported communication protocols

For RS-485: MODBUS-RTU, MODBUS-ASCII, IEC 60870-5-101, «ExtDev»

For Ethernet: MODBUS-TCP/IP and IEC 60870-5-104

Measured values can be displayed on AED and AEGD indication devices. AEGD can be powered directly from the transducer.
