About Low Tension Current Transformer (LT CT)

PowerTrac Low Tension Resin Cast Current Transformer

PowerTrac Low Tension Current Transformer (LT CT) is a resin-cast current transformer designed for low-voltage AC electrical systems. It is used to measure and monitor high primary currents by converting them into a standardized secondary current, with 5A as the standard secondary output. The transformer uses resin/epoxy insulation and is designed for reliable operation in electrical panels and industrial power distribution systems.

The LT CT range is designed according to IS 2705 / IEC 61869-2 and uses CRGO/silicon-steel cores. PowerTrac states that customized current ratios and VA burdens are available according to application requirements.
