Balfour Beatty Engineering Services is using an advanced tester from Clare Instruments to improve the electrical-safety testing of its power installations.

The company has replaced its previous electrical-safety tester with a HAL Combi to improve the accuracy and reliability of its product-commissioning procedures.

The HAL can undertake a range of electrical tests on the substation control and protection panels produced by BBES and then provide detailed analysis of each individual panel, including performance and outputs.

The HAL is part of the latest generation of test instruments, complete with specialist software and a large-capacity internal database.

Tests can be quickly configured into the tester by scanning in predefined bar codes that operate as test codes, making the equipment suitable for any ISO traceable application in quality control, conformance, or production-line testing applications.

These predefined barcodes can be generated directly from the test equipment on adhesive labels using the Test and Tag printer, or from proprietary Microsoft PC applications.

These barcodes can be incorporated into live test-procedure documents or the manuals required as part of ISO quality systems.

Specialist software and a large capacity internal database give the new generation of test instruments the ability to store test details and results against individual equipment serial numbers.

Test reports can be downloaded directly to a PC or printer for the production of complete test-data records.

In addition, the networking of test data with central management information systems allows the test station to become an important MIS data collection point, not only in identifying failure rates, but also by providing details of productivity levels and other information as part of quality audit trails.

Incorporating a new case design for space-efficient bench testing and equipped with highly intuitive user interface, operation of the HAL range of testers is achieved through the use of programmable soft keys and a rotary switch used in association with a large graphical display.

All HAL testers comply with the EN50191 safe operation of test equipment standard and are available with fully isolated test outputs.
