Electrical distribution systems are being subjected to higher loads and greater harmonics than ever. Real-time monitoring and remote control of power systems helps identify problem areas, pin-point the root cause, enable quick resolution, and if necessary, enact remote control of power distribution equipment. These actions prevent costly outages and loss of productivity and equipment, while extending the life of the electrical system.
System outages can be prevented or mitigated, equipment life extended, and costs reduced by monitoring key system wellness parameters such as:
Current, voltage and energy.
Power quality and harmonic content.
Environmental conditions, such as presence of water.
Power factor of transformer bushings.
Key events (oscilligraph).
With the advent of utility deregulation, having accurate power usage values enables you to negotiate a better position for power purchases. Plant-wide electrical power distribution system monitoring and control can be cost-effectively implemented during new construction. OEM products allow for communications through all levels of the power distribution and power protection network. For example:
The Cutler-Hammer Power Netsystem or Square D Power Logic System allows for plant-wide monitoring and control from a single workstation. Monitoring and control can also be accomplished from any number of workstations connected to a plant LAN, company, intranet, or the World Wide Web.
The Power Vision and Foreseer systems give administrators full visibility over networked UPSs across the enterprise, along with other elements of the critical facilities infrastructure.
The Insulgard relay can provide advanced notification of impending failure of MV equipment in time to have it repaired before catastrophic failures occur.
