Engineering

Protection engineering, scoped to the problem.

Three connected areas of work. Each can be engaged on its own — as an independent review, as engineering deliverables, or both — and each states what it covers and what it does not.

Areas of work

Choose the kind of support you need

Independent reviews, investigations and second opinions that help you decide what to do — and explain why. Calculations, settings, logic and documentation developed to an agreed scope, ready for your team's review and implementation.

01 · Calculation

Protection Studies & Settings Calculation

Short-circuit, coordination and relay settings calculations with a documented basis your engineers can review.

Scope, inputs and boundaries

Relevant when

  • The network has changed since settings were last calculated.
  • Trips have been non-selective or difficult to explain.
  • New equipment or a new installation needs settings.
  • Existing settings have no documented basis.

Advice & review outputsEngineering deliverables

  • Settings criteria and protection philosophy review
  • Independent review of existing settings
  • Review of disturbance and event records you provide
  • Review of third-party study reports
  • Short-circuit and coordination study report
  • Relay settings schedule with calculation references
  • Time–current coordination plots
  • Manufacturer-native settings files, where the platform, tools and scope allow
02 · Logic

Protection Logic & Scheme Design

Protection philosophy, programmable relay logic, I/O definitions and communications schemes that can be reviewed before they are configured.

Scope, inputs and boundaries

Relevant when

  • A new scheme needs its tripping, interlocking and breaker-failure logic defined.
  • An operation has raised questions about existing logic.
  • A panel builder or integrator needs I/O and signal definitions.
  • Hardwired signals are being considered for replacement by communications.

Advice & review outputsEngineering deliverables

  • Philosophy and scheme review
  • Review of logic after an unexpected operation
  • Hardwired versus communications-based signalling options
  • Interlocking and operating philosophy workshops
  • Protection logic diagrams
  • I/O and signal matrices
  • Logic test specifications
  • Relay logic configuration, where the platform, tools and scope allow
03 · Modernization

Protection System Modernization

Assessment and engineering support for replacing legacy protection, with interfaces, settings and phasing considered from the start.

Scope, inputs and boundaries

Relevant when

  • Relays are obsolete or spare parts are hard to obtain.
  • Documentation does not match the installation.
  • A wider upgrade or digitalization programme needs a protection plan.
  • Maintenance findings show unreliable or drifting relays.

Advice & review outputsEngineering deliverables

  • Fleet condition and obsolescence review
  • Retrofit versus replacement options
  • Phasing strategy
  • Owner's technical review of contractor designs
  • Modernization assessment report
  • Replacement settings, logic and I/O definitions
  • Test specifications
  • Input to cutover sequences and as-built documentation

Where to start

From challenge to engineering work

01 Unexpected or non-selective trips
02 Changes to the electrical network
03 Aging relays and protection systems
04 New protection designs

Tell us what your system is doing — and what you need it to do.

A few lines are enough to start. We will ask for drawings, settings or records later, through a channel agreed with you — there is no need to send them with your first message.
