ENGINEER THE INTERFACES

Make protection, bypass and performance explicit

A voltage optimiser is installed within an operating electrical system. The project must preserve safety, protective-device performance, fault-loop integrity, motor starting, power quality, maintainability and continuity of service.

Engineering scope
  • Continuous and short-time rating basis, including growth and ambient conditions
  • Electrical boundary, cable and busbar interfaces, earthing and neutral arrangements
  • Prospective fault level, protection coordination and discrimination
  • Output setpoint or reduction strategy and permitted tolerance
  • Interlocked bypass, isolation, fail states and remote/local controls
  • Metering, communications, alarms and data ownership
  • Enclosure, ventilation, access, fire and maintenance requirements
  • Interaction with generation, UPS, storage, capacitors and other controls
Installation planning

The installation plan defines responsibilities, outage windows, temporary arrangements, lifting/access, permits, inspection points, rollback conditions and operational communications.

Commissioning and acceptance
  • Verify approved drawings, identifiers, clearances, earthing and terminations
  • Test insulation, continuity, polarity, phase rotation and protection settings
  • Prove bypass and isolation sequences
  • Validate metering, phase mapping, clocks and data export
  • Energise under controlled conditions and confirm input/output voltage
  • Test representative load states, alarms, remote controls and fail conditions
  • Record service performance and obtain signed acceptance
Handover

Provide as-built drawings, settings register, test certificates, calibration records, operating procedures, warranty and service information, training and the agreed performance-review schedule.
