EL3453
EL3453 | 3-phase power measurement terminal up to 690 V AC with extended functionality
The EL3453 EtherCAT power measurement terminal is an advancement based on the EL3413. With up to 690 V AC, the voltage inputs are optimised for the direct monitoring of high-capacity generators, as in the wind power 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 63, rd, 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.
