EL3453 - Introduction
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 optimized for direct monitoring of high-performance generators, as used in the wind power industry, for example. No upstream voltage transformer is required.
The four current inputs are electrically isolated from each other and allow the terminal to be used in all common grounded current transformer configurations such as 2- or 3-transformer configurations with star or delta connection including neutral current measurement. Simple grid analyses are performed by the EL3453 up to the 63th harmonic analysis or summarized in the Power Quality Factor for simplified diagnosis. Like all measured values of the terminal, the harmonic content can be read via the process data.
A version with factory calibration and calibration certificate is available with the EL3453-0020.
The EL3453-0100 version is specially optimized for use including voltage transformers. It has a matched voltage measurement range corresponding to typical secondary side outputs of voltage transformers.
