The EL3453-0100 EtherCAT power measurement terminal has voltage

inputs for up to 130 V AC for connecting voltage transducers, enabling

the monitoring of medium-voltage systems, for example.

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 EL3453-0100 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 EL3453-0100 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 EL3453-0100 comes with the option of transmitting the

times of the last voltage and current zero crossing to thecontroller via

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

operations to suit the application.
