PRODUCT OVERWIEW
TR-ECT-10 electronic current sensor is suitable for 10KV column switch, ring main unit, three-phase bushing of column switch, mainly used for three-phase current and zero-sequence current measurement, measurement and protection of three-in-one Features. It is made of the principle of LPCT low-power coil and designed in accordance with the group standard requirements of T/CES 018-2018 "Technical Conditions for 10kV and 20kV AC Sensors in Distribution Networks". It can be matched with zw20 type, zw32 type high-voltage switch on the column, with low power consumption and high accuracy.
Product Features

Adopting the principle of LPCT low-power coil, it can directly output standard small signal without secondary conversion, and directly input secondary equipment through A/D conversion;

The magnetic core has high permeability and low temperature drift. In the temperature range of -40℃~+70℃, especially at -40℃, the variation of the error meets the standard requirements

Using low temperature drift resistance, it can work for a long time under 4 times the current, and work for a short time under the condition of 10 times overload;

At 30 times the current, that is, single-phase 600A, the zero-sequence output can work for a long time;

The secondary signal output adopts shielded cable to prevent interference.
