Description
ke-DP-01 3 Phase Voltage and Current Protection Relay x/5
General Informations
In three-phase systems, it measures RMS values of AC voltages, currents and system frequency sensitively. Using up direction button(Select), phase-neutral and phase-phase voltages monitor sequentially.
ke-DP01 has many features.
Those are;
– Phase Failure (seq)
– Phase Sequence (seq)
– Over Voltage Protection (o – U)
– Under Voltage Protection (u – U)
– Voltage Unbalance (asymmetry) Protection (unb)
– Over Current Protection (o – C)
– Under Current Protection (u – C)
– Current Unbalance (asymmetry) Protection (ubC)
– Over Frequency Protection (o – F)
– Under Frequency Protection (u – F)
When device is turn on if its adjusted voltages and frequency in its interval and if phase sequence is correct relay switch on. If any of error occurred ( except phase failure and phase sequence )
at the end of adjusted time relay switch off its contact. When systemreturn normal values, at the end of time out relay switch on.
