The EL3453-0120 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 EL3453-0120 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 EL3453-0120 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 EL3453-0120 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.

The EL3446-0011 EtherCAT Terminal enables measurement of

all relevant electrical data in the supply grid and performs simple

pre-evaluations. Since the EL3446-0011 itself has no voltage

inputs, the measured voltage values are transmitted via EtherCAT

from an EL3443 to be installed once per network.

to six – is fed in via simple current transformers. All measured

currents and voltages are available as RMS values.
