LDCs that own feeders connected to Hydro One Transformer Stations are responsible for establishing and updating protection settings for their feeders.

The Transmitter (Hydro One) owns the breakers and is responsible for applying setting changes and maintaining the protection settings and records. Hydro One will work closely with the LDC to ensure settings are applied accurately.

For Embedded LDCs connected to Hydro One-owned feeders, Hydro One will coordinate the feeder protection settings with you.
Protection & Control Management Information System (PCMIS)
The Protection & Control Management Information System (PCMIS) is a web-based system that houses protective relay setting information. Internet Explorer is the only requirement to use PCMIS. LDCs can view their feeder settings in PCMIS and can also request a feeder setting change by submitting a downloadable form.
