COMMISSIONING AND MAINTENANCE
Over the years, Gemitech has acquired unique expertise in commissioning large-scale projects, mostly in Quebec but also elsewhere in North America and in Europe. When it comes to low, medium, and high voltage substations, we have the experience and equipment to meet your needs. Our testing procedures meet IEEE, CSA, IEC, and NETA standards as well as all customer requirements.
Hydroelectric power stations and wind farms are two types of energy developments in which we excel.
EQUIPMENT TESTS AND MEASUREMENTS
- Liquid-filled power transformers
- Dry type transformers
- Low, medium, and high voltage circuit breakers
- Voltage and current transformers
- Low, medium, and high voltages witches
- Surge arresters
- Bushings and insulators
- Protection relays
- Cables (fault location, partial discharges, dielectric losses, tan delta)
- Grounding (continuity, step and touch voltage)
- Motor control center
In the same way a blood test can provide a doctor with a wealth of information about their patient, taking an oil sample enables service engineers to learn a great deal about the condition of a transformer.
Present and future transformer ratings require high quality and high purity insulating oils at the point of use. The increasing voltage and rating of the modern transformer and electrical apparatus results in greater electrical stress in insulating material and fluids. To handle these greater stresses, oils with better dielectric qualities are required. Also lower residual water content in insulating fluids and material must be maintained. The proper treatment and upgrading of the insulating fluid will result in the improvement of the properties of the entire insulating media of power transformers. The principal functions of the insulating fluid are to serve as a dielectric material and as an effective coolant. To perform these functions, the insulating fluid must have the necessary qualities at the time of initial impregnation and filling at the factory and later maintain the same quality in the field operation. Gemitech’s High Vacuum Process upgrades the new or used electrical insulating fluids including transformer oils, polybutenes and silicone fluids.
Gemitech’s (transformer oil purifier) high vacuum process is used for the dehydration and degasification of electrical insulating liquids including transformer oils, polybutene and silicone fluids, to increase and maintain their dielectric strength. The processing includes the removal of free and soluble water, dissolved air and gases and particulate matter.
Gemitech uses the ENERVAC degasser of 1200 gallons / hour and 65 KW of heating.
Gémitech is continuing its investments with the acquisition of a new fuller’s earth filtration system to increase the performance of its oil treatment unit!
This next-level oil filtration system absorbs acids, gums / glues, resins and other active soluble contaminants that may end up in your equipment.
Another improved solution that we are adding to our service offering to regenerate your oil in an optimal and ecological way while significantly increasing the life of your equipment, protecting your investments at the same time!
