HARMONIC STUDIES
Harmonic studies are normally performed to determine harmonic distortion levels and filtering requirements within a facility and to evaluate if harmonic voltages and currents are at acceptable levels. The recent development in technology is leading to high penetration of non-linear loads into the power systems. The non-linear loads lead to power quality problems in the power system due to the non-linear nature of the loads. The characteristic harmonic emissions of these non-linear equipment must be identified, studied and rectified with corrective measures to save on power consumption costs and meet the utility standards. This is where the use of a power quality study becomes imperative, as it can be critical in reducing the facility downtime and enhancing productivity.
With the growing proliferation of nonlinear loads in commercial buildings and industrial plants, which might become 30% to 50% of the total load, the effects of harmonics within the system and their impact on the utility and neighbouring loads needs to be examined before any penalty is levied, equipment is damaged, or production is lost.
OBJECTIVE OF HARMONIC STUDIES
- To evaluate the harmonic distortion levels and filtering requirements within a facility and to evaluate if harmonic voltages and currents are at acceptable levels.
- It investigates the root causes of a system with a history of harmonic-related problems, such as failure of power-factor compensation capacitors, overheating of cables, transformers, motors, etc., or mal operation of protective relays or control devices.
OUTCOME HARMONIC STUDIES
According to the IEEE 3002.8-2018, the outcome of this study is to design of a new facility or power system, where the load-flow, power factor compensation, and harmonic analyses are considered as one integrated study to determine how to meet the reactive power demands and harmonic performance limits.
Our team has certified professional engineers to analyse the harmonics in the system and give technical solutions to various problems. We closely work with the clients for the harmonic analysis study and recommend the solutions for industrial & commercial facilities.
