The energy efficiency of a piece of equipment is its power quality. Power quality issues result in excessive energy consumption and bills, high maintenance expenses, direct repercussions on the economy, productivity loss, unrecoverable downtime, and resources, and unstable or malfunctioning equipment. Any organization must consider energy management, and any energy management program must consider the quality of the electricity. Care Labs provides several services that address a variety of energy issues. We provide services for analysing and studying the quality of electricity, based on our knowledge in the industry.
The power supply’s quality is a more sophisticated and subtle metric than its dependability. It is irrelevant if there is sufficient supply. Instead, the question is whether the supply can be utilized. Changes in power quality may be divided into two categories:
1. Unrests:
Incorrect voltage or current might lead to disruption. When the peak value of a transient voltage exceeds a certain threshold, it is detectable. When the RMS variation exceeds a particular threshold, voltage variations such as sags, swells, and interruptions are detected.
2. Changes relative to the steady-state:
Changes in the steady-state include variations in the RMS voltage and harmonic wave distortion. Voltage and current must be monitored throughout time in order to keep track of these alterations. This sampling data is most effectively represented as the voltage distortion with time. It may then be analyzed using techniques such as the average distortion level, which has a 95% probability of not being surpassed, etc.
Among the factors that impact supply quality are:
The majority of these objects are tough to find and observe. To measure them, specialized testing equipment is often necessary, and only qualified technicians or engineers should do the tests.
Because of load and other system events, the steady-state voltage levels of an electrical system are constantly changing. In general, voltage levels decrease as the load increases. Similarly, removing a load raises the voltage level.
It is a discrepancy in the value or phase angle of the three-phase supply. Unbalanced circuit impedances and unbalanced loads can also cause it. It warms things up, degrades equipment, and reduces their effectiveness.
Voltage sags are brief decreases in the RMS supply voltage lasting between 0.5 cycles and one minute. Voltage swells are brief increases in the RMS supply voltage that exceed a threshold limit of 0.5 cycles to one minute.
The frequency of the supply is the rate at which the waves of the supply voltage variation. NEMMCO (National Electricity Market Management Company), which stands for National Electricity Market Management Company, manages the National Electricity Market. Outside of the National Electricity Market, the frequency norms are determined by the local producing authority.
It is a repetitive alteration in the pattern of the supplied voltage or current. Extra Harmonics can result in additional losses, flashing lights, malfunctions, radio interference, motor vibrations, and less efficient sensitive equipment.
