  • Integrating modern IED (Intelligent Electronic Devices) to SCADA systems
  • Protection system upgrades including investigation of existing protection systems and decommissioning
  • Capability with multi-vendor protection relays
  • Up-to-date designs with evolving grid and cyber security requirements such as NERC PRC/CIP (North American Electric Reliability Corporation)
  • Value added benefits of multi-function relaying
  • Design concepts with reliability, maintenance, and flexibility in mind
  • Integration services available to interface with third party installations
  • Co-ordination studies and TCC graphs

At LTL, our engineering team recognizes the challenges that arise with constructability during on-site changes. We are committed to managing these adjustments through the proper Engineering Change Notice process to maintain quality control and deliver a reliable final product.

Protection and Control Fabrication

The LTL team has experience in providing Protection and Control Panels to power industries, from high voltage transmission to municipal distribution systems.

Our quality control and testing services avoid costly impact on site installation and commissioning time.

  • Pre-wired panels allow for easy cost-effective integration into an existing system
  • Factory acceptance testing, and witness testing services ensures a reliable product
  • Relays pre-programmed with settings and fully function-tested
  • CSA inspection and certification
  • Connection Wiring Diagrams/Electrical Arrangement drawings can be provided as per client’s requirements
  • Wiring can be compiled simply from client’s requirements, I/O lists, or major equipment shop drawings

Pre-commissioning services are also available for relay settings provided by the client. These are put through our engineering review process to identify any issues before they get to site.

Substation Controls in a Box

Integrated modular packages offer cost savings and quality, providing a pre-engineered, fully integrated, protection, control, and automation solution.

  • Design-build solutions tailored to customers specific needs
  • Termination racks allow for easy interface wiring on site
  • Modular AC and DC power and Auxiliary Systems
  • Dedicated battery bank rooms include ventilation and automatic fan controls
  • Meets or exceeds all national building codes including fire rating, temperature, wind extremes, and seismic activity
  • Built to post-disaster construction specifications

Arc Flash Hazard Analysis

LTL’s Arc Flash Safety program includes a CSA Z462-compliant Arc Flash Hazard Analysis, labeling of all applicable electrical equipment, supply of all required personal protective equipment (PPE), and the option for classroom or online electrical training.

Our comprehensive arc flash studies determine potential arc flash incident energies and boundaries, shock hazard boundaries and proper personal protective equipment required for energized electrical equipment tasks for the system studied.

Performed by qualified engineers and technicians, LTL’s arc flash analysis includes:

  • Complete engineering services
  • Site assessment and data collection
  • Short circuit and protective device coordination studies
  • Labeling – warning labels identifying potential hazards and required safety equipment are affixed to all applicable electrical equipment
  • Easy-to-read detailed arc flash analysis reports
  • Supply of personal protective equipment for arc flash protection
  • Training – It is imperative that workers understand how and why the required PPE will help them as well as how to properly care for and inspect this equipment to comply with legislation

Legislation

The CSA Z462 states that an arc flash analysis shall determine the arc flash protection boundary and the personal protective equipment that personnel within the arc flash boundary shall use. The Canadian Electrical Code mandates that electrical equipment shall be field marked to warn persons of potential electrical shock and arc flash hazards.
