Electrical Power System Studies

Power system studies vary significantly In each design process depending on the purpose of the project. It would be better to have a complete study on your project rather than having missed one or two when audited. Several power system studies may be combined into A single report if having a single stand-alone document is not essential. The most commonly used studies are:

Cable Ampacity: Calculates the ampacity or operating temperature of cables.
Voltage Drop: Calculates the system voltage levels and the impact of a motor starting.
Protective Device Coordination: Plots the time-current curve at specified values for each protective device applied on the power system. Prints a one-line diagram of the associated portion of the system on the coordination curve for the plotted devices.
Motor Starting Torque / Acceleration Time: Using motor and load inertia and torque values, calculates the motor voltage and torque values during the accelerating period, and determines the overall starting time of a successful motor start.
Earthing and Lightning protection Study: Determines step and touch potentials and to identify hazard locations and provide design solutions.
Transient Stability: Calculates the response of dynamic loads to various system disturbances and to determine any unstable operating conditions requiring load shedding or other corrective measures.
Harmonic Analysis: Determine harmonic producing loads on a system and evaluate possible mitigations, i.e. harmonic filters.
Reliability / Availability: Determine failure rates and outage duration times for electrical equipment using statistical data to evaluate if redundant systems are necessary.
Fault Analysis: Calculates fault duties at every system bus to identify and select devices short-circuit capability.
Load Flow: Calculates the system steady-state conditions for both dynamic and static loads, and investigates various operating modes.
Lighting Design: Determines th e correct illumination levels for each task or area.
Generator Sizing: Using data for equipment availability to determine the size of generator for prime or standby power requirement.
