VAMP40 course – feeder: 5. Current circuits supervision, 2nd harmonic blocking function, free programable current curve

In the fourth article we configured non-directional earth fault protection and disturbance recorder. Full course of VAMP40 you can find here. In this article we are going to configure current circuits supervision, 2nd harmonic blocking function and free programmable current curve. It is important to control currents circuits. Broken currents circuits lead to damage current […]

VAMP40 relay – reading existing configuration and settings

VAMP40 relay is used mainly for feeders, motors, midlle voltage power transformers and capacitor banks protection. Relay has FBD logic (but in most cases you don‘t need FBD logic for simple scheme of feeders). Existing protection functions: current protections, undervoltage/overvoltage protections. First generation of relay VAMP40 was produced by company VAMP from Finland. Some couple […]
