If you own high voltage electrical equipment in a vault, it is important that you maintain your equipment through regular inspections and tests.
Hydro Ottawa’s top priority is to provide a reliable service while ensuring the safety of our customers and our employees. We do this by regularly inspecting, testing, and maintaining our equipment. Depending on the type of equipment in your hydro vault, Hydro Ottawa recommends that electrical service to the vault be shut down for maintenance, testing, and cleaning on a three or a six year cycle.
Hydro Ottawa provides customers with access to each of their vaults free of charge once per rolling 12 month period. These visits last up to two hours and are opportunities for customers to test their vault’s fire detector, check and service their ventilation system, and perform an Infra-Red scan of the vault’s high voltage equipment to detect possible problems. All of these services can be provided by your contractor(s).
Please submit your request for vault access or isolation through our online request form.
All vault shutdowns must be booked at least ten business days in advance. You can also learn more about this process by calling your High Voltage Contractor.
