Protective Device Coordination Study
TARGET ISSUE
High current faults can cascade upstream in a plant, tripping multiple devices and possibly a whole plant shutdown.
ABOUT THE SOLUTION
The study will lead to maximum power system reliability by ensuring that protection is selective and isolates the high current faults.
Most electrical power distribution systems are not planned with protective device coordination in mind. This is often the case when it has been composed of varying manufacturer’s equipment selected by several different individuals over years of operation.
Equipment faults can easily result if protection has not been coordinated throughout the entire plant.
The protective device coordination study by Actemium aims to maximize system reliability by ensuring protection is “selective”. The study will make recommendations so that only the local protection device operates to isolate the high current fault rather than cascading and tripping multiple devices upstream and perhaps a whole plant shutdown.
Coordination also avoids nuisance tripping incidents due to transformer inrush currents and/or heavy motor starting currents.
In a properly coordinated power system, the protective devices are selected and adjusted to minimize the impact of individual equipment failures upon the larger power distribution system.
