DP-01-72-100A 3 Phase Voltage and Current Protection Relay 100A

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 voltages 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 system
return normal values, at the end of time out relay switch on.
