The EL3453 EtherCAT power measurement terminal has voltage

inputs for direct monitoring of high-capacity generators up to max.

690 V AC, as is common in the wind industry, for example.

No upstream voltage transformer is required. The four current

inputs are electrically isolated so that the terminal can be used

in all common grounded current transformer configurations such

as 2- or 3-transformer configurations with star or delta connection

incl. neutral conductor current measurement.

The EL3453 can be used for simple grid analysis up to the 63rd

harmonics analysis.

Alternatively, all readings can be combined in a power quality factor

for simplified diagnostics. Like all measured terminal data, the

harmonic content can be read via the process data.

The EL3453 offers the “ExtendedRange” feature enabling the use

of the full technical measuring range, which equals 130% of the

specified nominal measuring range.

In addition, the EL3453 comes with the option of transmitting the

times of the last voltage and current zero crossing to the controller

via XFC technology. This can be used, for example, to carry out

switching operations to suit the application.
