Secondary Terminals
ability, EVT-C3- -10 voltage sensor secondary signal terminal and signalline have been specially shielded, and customized interface schemes can be provided according to customers' specific
Principle and Characteristics
EVT-C3-10 voltage sensor are based on the principle of capacitive voltage division and have the following advantages:
● 3 phases phase sequence and zero sequence voltage measurement and protection signal sampling can be realized.
● The secondary output is a safe low voltage 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.
● Can measure 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.
