Detail
Product Specification
ECT-L PD2 current sensor is high insulation strength by epoxy resin, safe and reliable, application for traditional switchgear and GIS switchgear, suitable for current measurement (measurement) and protection in AC 50/60 Hz lines with the highest voltage of equipment 40.5 kV and below.
Secondary Terminals
In order to ensure good anti- -interference ability, ECT-LPD2 current sensor secondary signal terminals and signalline have been specially shielded, and customized interface schemes can be provided according to customers' specific requirements.
Principle and Characteristics
The ECT-LPD2 current sensor is based on thelow- power coil principle and has the following advantages:
● One winding can simultaneously measure the current and protection signal.
● The secondary output is a safe lowvoltage signal, the power consumption is greatly reduced, and the heat outputis small.
● No secondary open circuit high voltage risk, increased safety.
● Product standardization, selection and ordering process simplification, fast delivery.
●Smallsize, light weight, easy to install.
Combined with the versatile intelligent feeder terminal (FTU), these excellent features will greatly improve power protection and monitoring.
