PLANT MAINTENANCE, TEST + MEASUREMENT

By adopting this technology at the refinery’s substations, the Natref plant managers can reduce maintenance downtime and implement a predictive maintenance programme, replacing circuit breakers as they reach the end of their service life and minimising unplanned downtime. Furthermore, by tracking all circuit breaker trips, problem areas in the system can now be identified by looking at repeated circuit breaker trips that previously would have gone unnoticed and undocumented. Omniflex is a specified technology partner of the Natref refinery for providing this alarm

The newly implemented alarm and events logging technology means maintenance engineers can see when an incident has occurred.

Monitoring the operation of circuit breakers at the substations had been a long-standing problem with no indication if one went off and had reset.

module which updates and synchronises time across the entire system so time in one substation is the same in the others, allowing for useful comparisons to be made across the plant on a unified time-base.

Benchtop test and measurement equipment

RS Components, a trading brand of Electrocomponents plc, a global omni-channel solutions partner for indus- trial customers and suppliers, is now stocking an ex- tensive range of RS PRO bench test and measurement equipment. The range includes programmable power supplies, oscilloscopes, waveform generators, digital multimeters, and arbitrary function generators, covering various functions and applications and providing a full suite of electronic instruments for customers in the engi- neering community. The RS PRO RSST-2000 series of insulation testers are electrical safety testers featuring a double insulation de- sign that makes them the world’s first to comply with the IEC 61010-2-034 safety standard. Comprising four mod- els, the series caters to a wide range of applications and each model includes features for greater functionality. The electrical safety testers provide a high-quality and high-efficiency solution to any electrical testing needs with an output capacity of 200 VA. As troubleshooting

tools they are ideal in preventing potential equipment failures before they occur. The primary test functions in- clude ac and dc withstanding voltage, ground bond, and grounding continuity. The series features output adjustment resolution, measurement resolution, controllable voltage ramp up and ramp down time settings and upper/lower lim- it judgement settings. The high illumination LED lights (flashing or permanently lit) and high-volume audio indi- cator provide warnings of the status during ongoing tests or judgement results from the safety analyser. Other features of the RSST-2000 series include 100 sets of manual test memory for storage of different test conditions; rear output terminal for system integration; and front panel remote control terminal mount/rear panel signal I/O for users to control the analyser’s output/stop, based on requirements. The RS PRO RSST-2000 series is competitively priced, carries the RS PRO Seal of Approval and car- ries a three-year warranty. The instruments have been through high-calibre compliance and quality testing to ensure quality, durability, and consistency. The full range of RS PRO bench test and measure- ment equipment is available to order online from RS South Africa and across sub-Saharan Africa. For more information contact RS Components SA.
