DP-02-72 3 Phase Voltage and Current Protection Relay x/5

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.

In one phase systems, it measures RMS values of AC voltage, current and system frequency sensitively. DP02-72-100A has many features. Those are;
– Over Voltage Protection (o – U)
– Under Voltage Protection (u – U)
– Over Current Protection (o – C)
– Under Current Protection (u – C)
– Over Frequency Protection (o – F)
– Under Frequency Protection (u – F)
When device is turn on if its adjusted voltage and frequency in its interval relay switch on. If any of error occurred 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.
