Every installation tested by trained engineers to exacting standards.
Every installation carried out by Beaumont Infrastructure is tested by trained engineers to exacting standards. Our testing and commissioning services ensure that all electrical infrastructure operates safely, reliably, and in accordance with design specifications and industry standards.
Our experienced commissioning engineers are equipped with the latest test equipment and are fully conversant with the testing requirements of all major equipment manufacturers and network operators.
Beaumont Infrastructure provides comprehensive cable testing services including 1kV and 5kV insulation resistance tests to verify cable integrity. DC pressure tests are carried out on cables up to 33kV to confirm insulation performance under elevated voltage conditions.
VLF (Very Low Frequency) cable testing is also available for high voltage cable circuits, providing a non-destructive method of verifying cable condition and identifying potential weaknesses before energisation.
Our transformer testing services cover HV and LV winding insulation resistance tests, winding ratio checks, and Bucholz relay testing to ensure correct operation of gas detection protection. Oil sample testing is carried out to analyse the condition of transformer insulating oil and identify any degradation or contamination.
All transformer tests are conducted in accordance with manufacturer specifications and relevant industry standards, with comprehensive test certificates issued upon completion.
Beaumont Infrastructure carries out comprehensive switchgear testing including AC pressure testing, ductor testing to verify contact resistance, and CT ratio and flick tests to confirm current transformer performance. VT ratio checks are also performed to ensure voltage transformer accuracy.
These tests are essential to confirm that switchgear operates correctly and safely, providing reliable protection and control of the electrical network.
Our protection testing services include primary and secondary injection testing to verify the correct operation of protection schemes. Timing tests are carried out to confirm that relays operate within the required time parameters for the protection grading scheme.
We test all types of protection relays including overcurrent relays, earth fault relays, and differential protection schemes. All protection settings are verified against the approved protection grading study to ensure correct discrimination and coordination across the network.
Beaumont Infrastructure provides soil resistivity measurements to determine ground conditions and inform earthing system design. Final earth electrode resistance testing is carried out to confirm that the installed earthing system meets the required design values and provides adequate fault current dissipation.
All earthing test results are documented and compared against design requirements to ensure compliance with BS 7430 and other relevant earthing standards.
Beaumont Infrastructure utilises digital pulse echo equipment for accurate underground cable fault location. This technology enables rapid identification of fault positions along cable routes, minimising excavation requirements and reducing the time needed to restore cable circuits to service.
Our fault location services are available for all voltage levels and cable types, providing a fast and effective response to cable faults across the UK.
