Outage Investigations
- From analyzing oscillographies and sequence-of-events to reconstructing timelines and determining root cause, PAC Engineering has the expertise to make sense of a system event and present the findings in an easily understood deliverable.
Coordination Studies
- PAC Engineering knows that you need the optimum Coordination Time Interval in all scenarios, whether you have a step distance scheme, directional overcurrent, or both.
Relay Settings Development
- PAC Engineering will take the pressure off when it comes to producing relay settings files, complete with calculations and rationale.
Protection Scheme Design
- We have experience designing protection schemes for a variety of systems including: breaker-and-a-half, ring bus, main-transfer with bus tie, transmission line protection with and without teleprotection, and three-terminal lines.
Base Case Modeling
- Maintaining a system model is an indispensable tool for knowing the impact of changes to your system. PAC Engineering can model your power system from scratch, or add to it, in ASPEN Oneliner, a powerful system oneline modeling application.
Relay Commissioning Support
- PAC Engineering can create and conduct intelligent commissioning test procedures for your new protective relay installation.
Protection Standards Development
- PAC Engineering has the expertise to help you develop a consistent, streamlined approach to implementing protective relay installations and the documentation that accompanies it.
Substation Automation & Control
- You may have the need for an advanced application, such as sequential relaying to isolate a fault and automatically restore service in stages. PAC Engineering can help you innovate new designs or improve upon existing ones.
