Independent electrical testing, commissioning and site validation support for critical power infrastructure, substations, renewable projects, industrial networks and grid-connected assets.
APS provides independent test and commissioning support for electrical assets where safety, performance, compliance and readiness for energisation need to be verified on site.
APS provides circuit breaker and contact resistance testing to verify the electrical and mechanical condition of switching equipment before energisation, after maintenance, or during asset condition assessment. The service can include timing tests, contact resistance measurements, coil checks, operating mechanism assessment and functional verification of MV/HV circuit breakers.
APS provides grounding system testing for substations, renewable plants, EV charging sites, industrial facilities and grid-connected infrastructure. The service can include soil resistivity measurement, earth resistance testing, continuity testing, current injection, and step and touch voltage measurements to support safety verification and earthing compliance.
APS carries out testing and verification of current transformers, voltage transformers, metering circuits and transducers to confirm ratio, polarity, burden, wiring integrity and measurement accuracy. The service supports protection, metering, control and revenue-grade measurement systems during commissioning and site acceptance activities.
APS provides power cable testing and diagnostic support for MV/HV cable systems, including sheath integrity checks, insulation assessment, continuity verification, phasing checks and fault location support. The service helps identify cable defects, installation issues and readiness for safe energisation.
APS provides power quality measurement and compliance assessment to evaluate harmonics, voltage distortion, flicker, unbalance, dips, swells and disturbance propagation. The service supports grid compliance, operational troubleshooting and investigation of power quality issues affecting sensitive electrical assets.
APS provides insulation assessment support for rotating machines, including motors and generators, where insulation condition, winding integrity and electrical stress need to be evaluated. The service can support commissioning, maintenance planning, fault investigation and asset condition review.
APS supports site acceptance testing and protection commissioning activities for electrical installations, substations and grid-connected assets. The service can include functional testing, trip checks, interlock verification, relay testing support, scheme validation and review of commissioning evidence before handover.
APS provides testing support for MV/HV switchgear and GIS equipment, including insulation checks, contact resistance measurements, functional verification, interlock checks and commissioning support. The service helps confirm that switchgear assemblies are safe, correctly configured and ready for operational service.
APS provides transformer, reactor and tap changer testing support to verify condition, insulation integrity, winding behaviour and operational readiness. The service can include winding resistance, insulation resistance, ratio checks, vector group verification, tap changer assessment and related commissioning checks.
Testing and commissioning are only one part of the project journey. APS also supports clients through specialist power system studies and independent technical consultancy, helping site evidence, engineering analysis and design decisions remain aligned.
Independent studies for grid connection, insulation coordination, power quality, protection coordination, cable rating, EMI and advanced grid dynamics.
Focused technical review and engineering advice for complex electrical infrastructure, project decisions and design-risk reduction.
APS connects site testing with specialist studies and technical consultancy, helping clients move from design review to field validation, commissioning evidence and confident project delivery.
