involves the use of computer programs to identify and predict potential harmonic problems and mitigation techniques. The study will also look at different operating points as well as system. Changes that might occur in the future. Transient Analysis & Surges:
The study will be conducted to record the transients & surges of 1 10/-610/ magnitude.
Voltage Dips Swells Analysis:
The study will be conducted to record the short term dips & swells along with magnitude & duration.
Reactive Power Analysis:
The study will be conducted to calculate the desired reactive power at distribution &load end. This w II give precise reactive power & maintain unity power factor at PCC & reduce losses & resonance in network.
Captive Power Analysis:
The study will be conducted to calculate the desired captive power. Synchronise the captive power to cater to peak demands & reduce utility surcharge& fuel consumption.
Flicker refers to variations in brightness due to small voltage fluctuations. These fluctuations are caused by the operation of various types of equipment connected to the network, such as arc furnaces, welding machines, motors, etc. Load Flow Analysis:
A load flow analysis is conducted to predict power flow magnitudes, power factor, voltage levels, and losses in branches of the system based on the specified operating conditions. The job for the Electrical system Power Quality study and analysis shall be carried out as indicated below:- Power Quality:
Power quality is often defined as the electrical network''s or ihe grid''s ability to supply a clean and stable power supply. In other words, power quality ideally creates a perfect power supply that is always available, has a pure noise-free sinusoidal wave shape, and is always within voltage and frequency tolerances
Why Measure Power Quality?
- Power Quality (PQ) refers to the reliable delivery of electrical energy in a form that enables electrical equipment to operate properly. When dips and swells, spikes, surges, momentary outages, sags or other disturbances occur—computers and other electrically powered equipment may malfunction, foil prematurely or shut down unexpectedly. Many facilities simply cannot accept these consequences. Consider hospitals, banks, data communications centers, manufacturing and other facilities that rely on smooth, reliable power for operations. The consequences of an unplanned outage can cost thousands of dollars each minute or result in unsafe conditions or other serious problems unsafe conditions or other serious problems.
- The RMS values of AC voltages up to 1000 V between terminals. By using the ratios, the device can measure voltages up to hundreds of gigovolts.
- The RMS values of AC currents up to 10,000 amperes. By using the ratios, the device can measure currents up to hundreds of kiloamperes.
- The DC components of voltages and currents.
