Nine Panamax bulk carriers in the CSL Great Lakes Seaway fleet were found non-compliant with Lloyd’s Register harmonic requirements during routine inspection. VFD-driven loads on each vessel were generating harmonic currents exceeding the limits. Mirus Lineator filters brought all nine vessels into compliance — documented with before/after measurements on representative vessels.
Систем једносмерног погона за бродове на мору произвео је напон довољно јак да изазове кварове контролног система на другим системима пловила. The vessel program was at risk of cancellation. A Mirus Lineator filter on the DC drive eliminated the notching — restoring compatibility between the drive and the vessel’s sensitive electronics. Documented with oscilloscope waveforms before and after.
The Marco Polo Cruise Terminal in Saint John required emergency lighting that met new fire and life safety codes for 190,000 annual passengers. An emergency lighting inverter was specified as part of the essential services infrastructure — the case covers selection, integration, and reliability requirements for port terminal power systems.
Canada’s oldest marine biological station at St. Andrews, NB, pumps seawater with two 100 HP pumps — whose speed and flow rate are controlled by variable frequency drives sensitive to supply quality. The case examines VFD-based pump control and power reliability requirements for continuous marine research operations.
Canadian Forces Base Goose Bay — a NATO training facility and alternate space shuttle emergency landing site — updated aircraft ground support power systems in Hangars 7 и 8. The case covers power quality and reliability requirements for military aviation infrastructure with no tolerance for downtime.
Међународни аеродром Халифакс Стенфилд захтева а 125 Батерија и пуњач Вдц станице као део континуиране надоградње подстанице. Случај испитује спецификације резервних батерија за рад аеродромске подстанице — критичну инфраструктурну апликацију где поузданост напајања једносмерном струјом директно утиче на све заштитне релеје.
