Brand-independent specialists in maintenance, testing, overhaul and retrofit of low- and medium-voltage circuit breakers. Available worldwide when reliability matters.
During scheduled maintenance, Sin-Ergy inspected, maintained and tested nine low-voltage circuit breakers on an offshore installation in the North Sea.
During a scheduled dry docking, Sin-Ergy maintained and tested the low-voltage power circuit breakers on an oceangoing vessel.
Maintenance for low voltage, transformers and medium voltage — complemented by retrofit and a digital Asset Passport.
Preventive maintenance, inspections and repairs in line with manufacturer specifications — brand-independent. We inspect mechanical parts, main contacts and arc chutes and perform primary or secondary current injection tests, micro-ohm measurements and insulation resistance measurements.
Preventive maintenance and condition assessment of transformers for a reliable power supply. We inspect connections, cooling, insulation and visible abnormalities.
Using the OMICRON CIBANO 500, we analyse operating times, contact resistance and coil and motor behaviour. With the Megger VIDAR, we test the vacuum integrity of vacuum interrupters.
Sin-Ergy modernises ageing electrical installations without replacing the complete system. Existing circuit breakers and protection systems are replaced or adapted using modern, reliable components that fit the current installation.
The Sin-Ergy Platform brings assets, maintenance records, test results, reports and technical documentation together in one digital asset passport. The complete technical history remains accessible after overhaul, retrofit or replacement.
