Practical electrical support for plant, machinery and the systems behind your operation. Altor works with industrial operators, contractors and site teams on installations, maintenance, difficult faults and commissioning support.

THE WORK WE CAN HELP WITH
A fault can involve the supply, motor circuit, drive, control wiring or a field device. Altor’s work spans these connected systems, with the investigation and scope agreed for your site.
Installation, replacement, testing and fault finding for motors and variable speed drives (VSDs). Discuss the motor, driven equipment and any recorded drive faults to help plan the work.
Electrical work on motor control centres (MCCs), control cabinets and associated wiring. Support includes installation, panel modifications, testing and diagnosis of power or control circuit issues.
Investigate failed equipment, electrical outages, unexpected trips and intermittent operation. Fault codes, operating conditions and the history of the problem help guide a structured investigation.
Electrical installation, testing and commissioning support for new or upgraded plant. Coordinate with contractors, equipment suppliers and site personnel on connections, access and the agreed testing scope.
PRACTICAL SITE SUPPORT
Overload indications, drive trips or an inconsistent start need investigation in the context of the equipment and operating conditions.
An instrument, relay, interlock or wiring issue may be preventing equipment from operating as expected.
You need electrical work coordinated with installation, a shutdown or equipment commissioning.

This site photograph shows variable speed drive equipment and electrical testing with a multifunction tester. It reflects Altor’s work with the power circuits and control equipment used in industrial installations.
The work starts with the symptoms, equipment history and the conditions in which the fault occurs. Testing and checks are planned around the site. Findings, completed work and any remaining recommendations are then explained to your team.
