NERC Protection and Control (PRC) Compliance Studies and Implementation
By simulating and modeling customer power systems, 3i0 provides recommendations and implements necessary changes to ensure compliance with NERC relay performance standards.
Recent NERC Compliance Projects
PRC-019 — Coordination of Generating Unit or Plant Capabilities, Voltage Regulating Controls, and Protection
PRC-024 —Frequency and Voltage Protection Settings for Generating Resources
PRC-025 – Generator Relay Loadability
PRC-026 — Relay Performance During Stable Power Swings
PRC‐027 — Coordination of Protection Systems for Performance During Faults
Generator, Transformer, Bus and Line Protection Upgrades Using New or Existing Panels
3i0 designs, installs, commissions and tests new protection panels or custom doors for existing protection panels, replacing aging electromechanical relay schemes with modern multifunction protection relays. The new relays allow for more reliable and flexible protections that can easily be modified to comply with the evolving requirements and needs of NERC and the IESO.

Teleprotection Projects
3i0 designs, installs, commissions and tests new teleprotection schemes. Customer connections to Hydro One’s grid often involves implementing transfer-trip and blocking signals over various mediums such as leased circuits and fibre optics.
Recent Teleprotection and Telecommunications Projects
Transfer Trip and Blocking using FSK to and from Hydro One
Customer Transfer Trip and SCADA backbone using digital leased circuits
Arc Flash Analysis and Coordination Studies
Using power system modeling software, 3i0 models entire power systems. All equipment ranging from 230 kV to 208 V can be incorporated including: switchgear, motor control centers and all related loads, DC systems, distribution panels, UPS systems, lighting transformers and protection devices. This provides customers with a detailed model for their records. Coordination, equipment duty, and arc flash studies can then be carried out to provide updated labels for all equipment as well as a list of recommendations to rectify any safety concerns.
Recent projects involve sites with several hundred buses
