Ensuring optimal power quality at the connection point is vital to prevent undesirable electrical disturbances and protect sensitive equipment. The OEB has created a guide for customers to go over the steps of determining power quality issues and the responsibilities for customers and your distributor (NOTL Hydro) for identifying poor power quality and it’s source.
This Guide to Addressing Electricity Distribution Power Quality Issues (Guide) provides an overview of power quality issues, including their identification, investigation, and mitigation strategies applicable to customer facilities before and after their connection to the electrical distribution system (below 50kV). Specifically, this Guide is intended to assist both customers and distributors in collaboratively managing power quality, providing a uniform practice for distributors to address power quality issues throughout Ontario.
