| | Utilities periodically need to update standard equipment specifications or develop specifications for unique or new situations. PSE can help prepare specifications and assist with the procurement process including: |
|
|
- Construction project and material specification development: for transformers, circuit breakers, relaying, generators, capacitors, regulators, monitoring, and control equipment.
- Preparation of request for proposals for turnkey projects for generation, transformer vaults, line extensions and conversions, and substation additions.
- Evaluation of quotes, bids and proposals for equipment and construction projects.
- Design tasks.
|
|
| | Utility staff can often be faced with a variety of relatively small system improvements or repair projects that have an engineering design element. Due to resource constraints or the rarity of the situation for the utility, the staff at the utility may desire outside assistance. PSE provides this type of assistance to its engineering clients on an as needed basis. Examples of services PSE provides include: |
|
|
|
- Determine and/or program configurations for equipment including regulator controls, load tap changer controls, capacitor controls, recloser controls, and revenue and survey metering.
- Size fusing, conductors, conduit, transformers, capacitors, reclosers, potential transformers, and current transformers.
- Perform motor starting analysis.
- Interpret electrical codes on services, grounding, transformer locating, line design, and other matters as needed.
- Design peak alert metering and alarm and control systems.
- Perform system protection analysis for overvoltage, overcurrent, and grounding.
- Design loop transfer systems.
- Design substation modifications.
- Perform transformer loss evaluations.
