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.

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.

The current in the connectable phases – of which there are up

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

currents and voltages are available as RMS values. 

In the EL3446-0011. the active power and the energy consumption

for each phase are calculated. RMS values are available for voltage

U and current I as well as active power P, apparent power S,

reactive power Q, frequency f, phase shift angle cos φ, and

harmonics. The EL3446-0011 offers options for comprehensive

network analysis and energy management.

evaluating differential current transformers (such as the SCT4xxx)

and DC-capable current transformers.

The EL3443-0020 EtherCAT Terminal enables the measurement

L1. L2 and L3 is fed via simple current transformers.

All measured currents and voltages are available as root-mean-

square values. In the EL3443-0020 terminal, the effective power

and energy consumption for each phase are calculated.

The RMS values of voltage U and current I as well as the active

power P, apparent power S, reactive power Q, frequency f, phase

shift angle cos φ and harmonic are available. The EL3443-0020

offers extended functionality for mains analysis and energy

management.

In addition, the EL3443-0020 comes with the option of transmitting

the time of the last voltage zero crossing to the controller via XFC

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

operations to suit the application.
