Detail
Product Specification
EVT-C2- 20 voltage sensor is a capacitive voltage division structure, epoxy resin casting, high insulation strength, suitable for voltage measurement (measurement) and protection in AC 50/60 Hz lines with the highest electric voltage of 24 kV and below.
Secondary Terminals
In order to ensure good anti-interference ability, EVT-C2-20 voltage sensor secondary signal terminal and signal line have been specially shielded, and customized interface schemes can be provided according to customers' specific
Principle and Characteristics
EVT-C2- -20voltage sensor are based on the principle of capacitive voltage division and have the following advantages:
●Phase sequence or zero sequence voltage measurement and protection signal sampling can be realized.
●The secondary outputis a safe lowvoltage signal, the power consumption is greatly reduced, and the heat output is small.
●No ferromagnetic resonance, no need to configure fuse protection.
●No secondary short circuit high current risk, increased safety.
●Canmeasure DC and low frequency AC signal.
●Product standardization, selection and ordering process simplification, fast delivery.
●Small size and light weight, easy to install
Combined with the versatile intelligent feeder terminal (FTU), these excellent features will greatly improve power protection and monitoring. .
