Description
OM-310 Numeric Power Management System is used for:
- Power Monitoring
- Demand Controlling
- Generator protection
- Overcurrent protection
- Earth leakage protection
- Voltage monitoring
- Complete load rejection when the power consumption exceeds the main threshold for a user-set time
- Partial load rejection when the power consumption exceeds the main threshold for a user-set time
- Measurement and indication of three-phase electric circut parameters (active values of phase and line voltages)
- Positive, negative and zero phase sequence voltages; active phase current values; active, reactive and full power load consumption, power factor
- Emergency signaling
- Remote monitoring and load activation/deactivation via the RS-232/RS485 interface or external switch
The device allows working with a load of 2.5 – 30 kW with the use of integrated current transformers, and with a load of up to 450 kW with the use of external current transformers, including in networks with an insulated neutral.
We offers the consumer the following protection types:
- Low-quality network voltage (unacceptable power surges, phase breaks, phase sequence disruption, phase/line voltage distortion)
- Current exceeding the maximum allowed value on any of the load phases
- Ground leakage currents
- Automated reclosing can be allowed or forbidden for each type of protection
- Electric equipment is protected by means of controlling the magnetic starter coil (contactor)
