Issues related to electric power quality can be effectively managed if industries adopt solutions like those discussed below.
Solutions to voltage sags – Most voltage-sags can be reduced by using Ferro-resonant transformers. Often known as constant-voltage transformers (CVTs), these conditioners are ideally suited for constant, low-power loads. Load voltage controllers or UPS’s are some other options that can help tackle sag based on sensitivity and response time need.
Solutions to Harmonic Problems – One of the possible methods is to use harmonic filters to divert harmonic current from the facility’s equipment. Plus, adding reactors or isolation transformers on the feeders connected to harmonic producing loads can be a great idea.
Solution to Motor Issues – This can be carried out by adjusting the voltage unbalance and the incompatibilities between adjustable-speed drives and motors.
Solutions to Surges – Voltage surges caused by lightning or switching can be mitigated by surge-suppression devices. Such devices protect equipment by diverting the energy to the ground when the voltage exceeds the breakdown voltage of the device.
Solutions to Electromagnetic Interference Problems – Electromagnetic interference problems can be managed through four methods – proper grounding, attenuating emissions at the source, shielding sensitive equipment, and capturing and returning emissions to the source. Also, using reactors at the input of an Adjustable Speed Drives (ASD) or connected to its DC link is the most cost-effective way to minimize the effect of capacitor-switching transients on ASDs.
Keeping an eye on the power quality also results in reduced energy consumption. Icopower ESCO is an Independent Energy Service company which develops, implements, and,in order to improve the energy efficiency for facilities over a 3- to 5-year time period, arranges its own project financing. The mission of Icopower ESCO is to analyze, design, and implement energy efficiency solutions that will create value for facility owners and operators across all sectors in East Africa and beyond.The vision is to contribute to prosperity throughout the region, generating benefits for the economy, the environment, and for society according to the triple bottom line of sustainable development.
