Yes, by optimizing voltage levels and reducing fluctuations, voltage stabilizers can contribute to energy savings and improved efficiency in electrical systems.

Yes, when installed and maintained correctly, voltage stabilizers are safe to use and help mitigate risks associated with electrical fluctuations.

Regular inspections, cleaning, and calibration are recommended to ensure the proper functioning of the stabilizer. It is also important to check for any signs of wear or damage. 

Factors to consider include the required capacity (in kVA), input voltage range, output voltage precision, type of load (resistive or inductive), and specific application requirements.
