Common use of Power Quality Requirements Clause in Contracts

Power Quality Requirements. All power quality parameters (i.e., voltage, flicker, frequency, distortion) are specified at the point of common coupling (PCC) unless otherwise stated. The following requirements must be met: 4.4.1. Voltage – the System shall be capable of operating within normal voltage operating limits of 120 volts or other voltage corresponding to the City's service voltage at the site.This range results in trip points at 105 volts and 133 volts. Response to abnormal voltages should be as follows: Voltage (at PCC) Maximum Trip Time V < 50% 10 cycles 50%  V < 88% 120 cycles 88% < V < 110% normal operation 110% < V < 120% 60 cycles V  120% 10 cycles

The following requirements must be met: 4.4.1. Voltage – the System shall must be capable of operating within normal voltage operating limits of 120 106-132 volts or other voltage corresponding to the City's service voltage at the site.(00 -000% nominal 120V). This range results in trip points at 105 volts and 133 volts.
