• Reductions  outage  time within the plant as a result of  the system style and instrumentation are changed to scale back  mean  time  between failures and mean time to repair.
• Power Quality are considerably improved due to reduction in harmonic currents and voltages.
• Reduction in outages due to unstable generator power swings  following fault clearing.

• Electrical Safety is conjointly improved as as potential harmonic resonance conditions corrected and also because of identification and elimination  of overvoltage and overcurrent things.
• Improved operations whereas islanded conditions thanks to implementation of load shedding scheme.

Short Circuit Study

The contact study tells us the capability of every element in an electrical system. Here throughout this study all reasonably inputs expected   is delivered to the instrumentation into consideration. The results are tabulated and analyzed.

Coordination Study

The coordination study is conducted to work out the extent of overcurrent protecting device coordination among an electrical system . A Well-engineered system can enable solely the protecting device nearest the fault to open,  leaving remainder of the system undisturbed so the systems remain in service.

Arc-Flash Hazard Analysis

Arch-Flash studies analysis the results from short-circuit and coordination studies to search out the arc-flash incident energy levels. This studies are conducted beneath all conditions and every one modes of operation that the element could face.

Load Flow Studies

Load flow analysis could be a numerical algorithm accustomed perceive the steady state operational characteristics of a power system network from data knowledge or bus data. Load flow Studies helps in decreasing sudden period, and it reduces opera rating and maintenance prices.

In this study, the target is to analyze the behavior of the motor that's being started and its effect on system operations. As such, the motor terminal voltage, motor beginning current and bus voltage is aforethought.

This section describes the Motor beginning study basis and results. Motor beginning studies are performed to work out the strategy of motor beginning with success whereas maintaining the voltage at the motor terminal and in different buses among acceptable limits.
