The Mirus Lineator wide spectrum passive harmonic filter, a well proven method of mitigation in offshore and marine environments, still remains the best technical solution to treat harmonics. It not only addresses all requirements to meet full compliance of certifying body harmonic distortion 'rules' worldwide, it is guaranteed to outperform all other passive and active solutions. The Lineator is now available in a hardened version specifically designed for severe marine and offshore applications.
Lineator can be maintained ‘on the run’
The Marine & Offshore Specific Lineator can be optionally configured for service and maintenance of the capacitors without powering down the reactor. A circuit breaker isolates the capacitor bank which is compartmentalized for safe access by qualified electrical staff. The system can temporarily operate on the reactor alone with reduced harmonic mitigation. This eliminates operational shut-downs thus ensuring your main propulsion, drilling operation and production is always up and running.
Note that even with all capacitors disconnected, the performance of the Lineator reactor alone will be as good as a 12 pulse system so it "will get you home" every time.

Note: Lineators are 12-15% kVAr compared to 28-40% kVAr for competitive filters. Lineators therefore do not normally require capacitor switching on generator derived supplies.
