An existing 7.5 MW steam turbine generator had antiquated governor / field controls, which impacted on performance. Utility surcharges were being experienced and response was poor on load variation.

Calgary office designed, built, installed, and commissioned new generator controls while the plant continued to run. This involved on-line modification and correction of pre-existing control problems as well as synchronization and performance testing.

Magna IV Engineering Ltd provided analysis of existing plant loading and impact of proposed expansion. Upgrades included a new utility connection and 15KV outdoor switchgear install. A 5MVA transformer, expansion to existing 5KV switchgear and installation of a new UPS battery supply and central mimic panel were also part of this project. At this same time ongoing annual maintenance programs were implemented.

Crown Cork and Seal manufactures aluminum cans for various vendors throughout Western Canada. Our Calgary office was designated to specify, supply and install 600V cables and equipment. Equipment was sourced from after market sources as well as new.

The project involved upgrading primary sources including protective devices, transformers and cables. A facility short circuit and co-ordination study was prepared. The necessary loads were added to the existing 600 volt switchgear. Power factor correction capacitors were added to compensate for the new load. Future expansion proposed for this facility is scheduled to be undertaken in 2000.

Magna IV Engineering (Calgary) Ltd. has been closely involved in the maintenance and upgrading of this facilities electrical distribution system. This has included infrared surveys, relay calibration, a digital metering system and software and emergency services. We have also assisted in short and long term planning for insuring continuity of service to critical computer loads.

Calgary office provided engineering input and assistance from project inception to completion. This work involved co-ordination and interfacing utility substation modifications with new plant equipment. New and upgraded equipment included a 5KV metal clad line up, addition of a second standby generator and 600 volt additions. Along with equipment upgrades a digital metering and control system was implemented. A plant wide protective relay co-ordination and short circuit study was included.

Magna IV Engineering Ltd. continues to provide ongoing annual maintenance and specialized assistance to the plant.

Our office has assisted through several facility expansions and modernization of equipment. The equipment has been designed and built in direct consultation with the plant and resulted in significant cost savings without sacrificing performance.

The medium voltage synchronous motor controllers incorporate several unique capabilities which were specifically required by the clients process (see products this web site). The power distribution centers were built to match the existing site requirements "5000 volt primary feed - 480 /277 volt secondary loads."

All equipment was pre-manufactured tested and made ready for installation during rather narrow shutdown opportunities. Our Calgary office continues support and technical assistance to the plant as well as annual maintenance and inspections.

Magna IV Engineering (Calgary) Ltd. has been associated with this client for many years. Our services have expanded to the point where we are an integral part of the electrical department maintenance and planning execution.

Our work has included emergency services, service entrance upgrades and retrofits, digital metering installations and implementation, protection upgrades and various other engineering tasks.

During a scheduled shutdown antiquated ground fault monitoring was replaced with modern technology rack mounted equipment. Magna removed all old ground fault relaying, replaced with new and commissioned the system. Site instruction was included.

At this same time routine shutdown assistance such as relay calibration, breaker and switchgear tests, cable testing and general inspections and cleaning was performed. We have also assisted in implement the plant digital metering system and continue to provide support as requested.

This client has utilized our skills in many different areas. Our work has included 138KV substation repairs and testing, plant wide coordination study, distribution system expansion, drawing as built services as well as system and protection upgrades.

In addition our company is used to confirm plant grounding integrity and provide maintenance testing services on and extremely large medium and low voltage distribution system.
