Power System Analysis & Protection Design
Comprehensive Power System Studies
Universal Guard (NT) is a highly capable and experienced provider of electrical power system analysis services, with a focus on power system modelling, protection studies, and design.
Our team of experienced engineers and technicians have the knowledge and expertise to provide comprehensive solutions that meet the specific needs of each project, ensuring safety and efficiency.
Power system modelling
Using ETAP, PTW and PowerCad software.
Protection system studies and design
Including coordination and selectivity analysis. Protection schemes include overcurrent and earth fault, directional and non-directional, motor, high and low impedance differential, distance protection, and IEC 61850 communication systems.
Arc flash studies
Including IEEE1584 incident energy calculations, hazard and risk assessments and labelling, mitigation measures and protection optimisation.
Load flow studies
Including steady state and dynamic analysis such as motor starting studies, analysis of load diversity, equipment rating checks and sizing, voltage and tap changer position analysis, effect of power factor correction (PFC).
Harmonic studies
Including source identification and mitigation recommendations. Analysis includes establishing resonance points, effects on Ripple Control schemes, effects of and on PFC schemes, filter analysis and specification, and Connection Point limit checks.
Insulation coordination studies
Including equipment and system Surge Protection evaluation and specification to protect transformers, switchboards, and downstream equipment.
Short circuit studies
Including fault current calculations and equipment rating checks typically using IEC60909 methods and checking switchboard peak ratings, CB peak and breaking ratings, cable ratings.
Transient Stability Studies
Analysing effects of system disturbances such as generation changes, faults, and load addition/rejection, results typically being used for optimising of Load Shedding schemes.
Equipment Reliability studies
Allow recommendations to be made on upgrades and protection improvements, spares options and optimising switching configurations. Evaluation uses published or actual reliability figures for installed equipment.
