Abstract

A terminal block for current measurement in a power grid. The terminal block includes a shunt and a temperature sensor, and is configured to be connected to an Intelligent Electronic Device IED and a primary device. Furthermore, a respective IED and a system for current measurement including the IED and the terminal block are disclosed as well as a method for calibration of the system and a method for current measurement in power grids. A voltage measurement unit in the IED is adapted to measure a voltage drop at the shunt; a current flowing through the shunt can be calculated from the temperature and from calibration data. The terminal block enables a particularly efficient calibration method.
