WebMay 6, 2024 · The main use of CT transformer based current sensing technique is in the Power grid due to very high current measurement capacity. Few clamp meters also use a current transformer for the measurement of Alternating current. Shunt Resistor Current Sensing Method. This is the most used method in current sensing techniques. WebWhat is a coaxial shunt? A shunt resistor is placed directly into the current path. It is therefore not floating, and is normally only used where circuit potentials are low. The voltage across the shunt provides an absolute measurement of current. A ‘coaxial’ shunt is a resistor that has been designed to have almost no inductance (e.g. 2 nH).

WebApr 9, 2024 · Thermal considerations are crucial for an accurate current measurement when a shunt resistor sensitive to the temperature is used. The resistance value of a resistor depends on its temperature. The variation is proportional to the Temperature Coefficient of Resistance (TCR) that depends on the resistor material. WebShunts may also be referred to as ammeter shunts or current shunt resistors. Shunt resistors are commonly used to measure high currents, with the low levels of associated resistance. Shunting literally translates as diverting or following a force along a set path. There are a number of instances in which the measurement of current will be required.
