PureSine Ltd

Power quality consultancy offering harmonic assessments, power quality analysis and specialist testing services. Measure, manage and mitigate power related issues. Whilst we're based in the Cambridge area, we travel nationwide to carry out power quality related assessments and investigations. Some of our most common services include (but are not limited to): - G5/5 harmonic compliance studies, consulting, voltage assessments and harmonic current injection tests. - Harmonic Analysis, typically in the form of week-long analysis to measure harmonic levels following major works, specify active harmonic filtration or investigate harmonic-related issues. - Power Quality Analysis; investigations into unknown causes of power related issues or premature failure of sensitive equipment. - Power Quality Health Checks; regular short term load and harmonic studies to stay on top of load changes and ensure active harmonic filtration is operating as expected. - Voltage transient capture and analysis. - Inrush current testing and/or investigations. - STS testing; verifying correct operation of static transfer switches according to their expected/required response times. - UPS shock load testing; ensuring that voltage dips aren't too severe during load transfers. - Metering verification; confirming that metering systems are correctly setup and providing accurate measurements. Please feel free to get in touch if you're experiencing power related problems on yours or your clients' site. Response times are fast and site visits can usually be arranged within 1-2 weeks, and potentially much sooner if mission critical.
