Current transducers for rail traction applications

25 January 2012 Test & Measurement

LEM has released the ITC series of transducers for galvanically-isolated, high-precision current measurements in rail traction applications. The new transducer series comprises three models – ITC 1000-S, 2000-S and 4000-S – with corresponding nominal current measurement ratings of 1000, 2000 and 4000 ARMS. LEM designed the ITC series for the rail-traction industry sector, reaching the Class 0.5R measurement accuracy. The ITC series features linearity error of under 0,05% with offset currents of less than ±20 μA.

The rail traction industry requires unprecedented accuracy, necessary of course to maintain optimum control of traction motors, but mainly in energy metering to log energy usage for fiscal purposes, for example in billing power costs for trains that cross regional borders. Precise energy metering depends on accurate current and voltage measurements, and LEM has a complete offering for both of these measurements. Used together with highly accurate voltage transducers such as the LEM DV series, and an energy meter such as LEM’s EM4T, ITC-series current transducers bring the necessary class accuracy.

Their high accuracy makes the ITC transducers suitable for use in a broad array of differential current measurement applications where 0,5% accuracy, over 5% to 150% of nominal current, is required.
