Yes, dry-type transformers can be used in the oil and gas sector. Dry-type transformers are favoured for use in hazardous environments such as oil and gas production and processing facilities, due to their increased safety compared to oil-immersed transformers. Dry-type transformers do not use oil for cooling or insulation, eliminating the risk of fire, environmental contamination and electrical discharge.
In the oil and gas sector, several factors are important when considering the use of dry-type transformers:
Safety: Safety is of utmost importance in the oil and gas sector as operations can be hazardous, with the presence of explosive gases, dust, and moisture. Dry-type transformers do not use oil for cooling or insulation, making them a safer option for use in these hazardous environments.
Reliability: Reliable power supply is critical in the oil and gas sector, as operations can be disrupted by power outages. Dry-type transformers are designed to be more reliable compared to oil-immersed transformers as the characteristics of dry-type transformers do not change over time as is the case with oil. Tap changing, whether off circuit or on, is also simpler and more reliable than oil type.
Maintenance Requirements: Equipment maintenance can be time consuming and costly in the oil and gas sector, particularly in remote locations. Dry-type transformers require less maintenance compared to oil-immersed transformers as they do not require regular oil sampling and testing. Time taken for maintenance is greatly reduced as there is less required. Simple testing of protection relays and temperature probes and in some cases blowing of excessive dust is all that is required.
Energy Efficiency: Energy efficiency is important in the oil and gas sector as energy consumption can have a significant impact on operating costs. Dry-type transformers can be designed to the highest efficiency levels possible and the fact that only air is used as an insulation and cooling medium means they are more efficient than oil type transformers when used in an AF application.
Customisation: The oil and gas sector has a wide range of power distribution requirements and it is important to use equipment that can be customised to meet specific needs. Dry-type transformers can be customised to meet the specific voltage, power and environmental requirements of the oil and gas sector.
Considering these factors will help ensure that dry-type transformers are used effectively and safely in the oil and gas sector.
