Service scope

Electrical and controls expertise for generator reliability

Ultima Control supports parallel generator systems where sets fail to synchronise, share load poorly, circulate reactive power or sequence incorrectly.

Our specialist scope: generator electrical systems, controls, protection, wiring, switchgear interfaces, communications and SCADA. Where a fault is mechanical, fuel-system or engine-internal, we can identify the control-system evidence and coordinate the electrical interface with the appropriate mechanical specialist.

What we can do

  • Voltage, frequency, phase and breaker feedback checks
  • Synchroniser and load-sharing controller diagnosis
  • Governor and AVR control-signal verification
  • kW and kVAr sharing setup and testing
  • Generator sequencing and power-management logic review

What you receive

  • Stable synchronising and breaker closure
  • Balanced active and reactive load sharing
  • Verified generator availability and sequencing logic
  • Recorded settings and test results where included in scope

Useful information for your enquiry

  • Generator make, model and rating
  • Controller, AVR or protection make and model
  • Fault codes, alarm history or operating symptoms
  • Photos of the generator, control panel and switchboard
  • Site location, access constraints and operational priority

Frequently asked questions

Planning your service

What should I provide before a service visit?

Send the site location, generator rating, controller or AVR model, fault codes, photos and a description of the required operating outcome.

Is this service limited to emergency generators?

No. The electrical and controls scope can apply to standby, prime-power and parallel diesel generator installations, subject to equipment and site requirements.
