More Definitions of System Disturbance

System Disturbance is defined in Section 4.02.

System Disturbance shall be deemed to exist if the use of power by Customer directly or indirectly results in a risk of harm to human beings or material damage to or substantial interference with the functioning of Big Rivers’ generating system or transmission system, Seller’s distribution system, or the plant, facility, equipment or operations of any customer of one of Big Rivers’ distribution cooperative members. A System Disturbance includes, but is not limited to: (i) a level of current harmonic total demand distortion (“TDD”) measured at the Delivery Point that exceeds the limits on TDD described in IEEE Standard 519, Section 10; and (ii) a use of capacity and energy in such a manner that causes a current imbalance between phases greater than five percent at the Delivery Point.

System Disturbance. As defined in Secfion 5.1.

System Disturbance means an unplanned event that produces an abnormal System condition such as high or low frequency, abnormal voltage or oscillations in the System, but does not include a dispatched Load curtailment to restore the energy balance based on an inadequate energy supply.
