Global Gas Density Monitors in High Voltage Gas Insulated Switch Gear Market Research Report: Forecast (2023-2028)

Market Definition

The Gas density monitor is a portable device used to measure the gas pressure and density of the gas, SF6 in case of high voltage gas insulated switch gears. It is also used in industrial applications, including oil and gas production, welding, and gas processing. Because the Gas Density Monitor works on the principle of reference gas comparison, no temperature compensation is required.

Market Insights

The Global Gas Density Monitors in High Voltage Gas Insulated Switch Gear Market is projected to grow at a considerable CAGR during the forecast period, i.e., 2023-28. The power substations and distribution systems are constantly evolving, driving demand for dependable and affordable medium- and high-voltage installations. Because of this, monitoring gas-insulated switchgear (GIS) has also typically grown in significance. Several different types of technology may be used to monitor and analyze GIS, particularly concerning gas density. It is primarily because SF6 is a greenhouse gas, over 20,000 times more potent than CO2, and accurate monitoring of SF6 leakages is vital.

Moreover, the rising investments in infrastructure development, expansion, and development of renewable energy sources for power generation and the increased demand for industrial development have maximized the installation of high-voltage gas-insulated switchgear. This enlargement has paved the way for raised adoption of gas density monitors required by such switch gears in the long run.

Additionally, the tangible global presence of market players has further stiffened the competition within the industry. For example, one of the leading Companies, Trafag AG, which entered the high-voltage SF6 insulation gas density monitoring market by cleverly combining a pressure switch with thermostat components, has been in the industry for more than four decades. The brand has been honored as a pioneer in electronic density sensors and gas density monitors with a reference gas chamber.

Likewise, the ABB MSM and other contemporary SF6 monitoring systems provide solutions utilizing top-tier technologies. However, it would be exceedingly challenging to discern drift errors from a progressive decrease in gas density. Because of this, ABB uses drift-free sensors, much like a quartz watch. Thus, with continuous developments and innovation by the industry players, the market would witness steep enlargement in the forecast years.

Market Dynamics

Key Driver: Upgrading Substation and Switchgear Technologies worldwide

The rising need to ensure an uninterrupted power supply has called for massive worldwide investment in power distribution networks. Consequently, power utilities are focusing on substation and switchgear technologies that require less space and reduce outages. Given this, the need for improved monitoring systems has arisen. Further, since industrial development around the globe needed more power and protection units, high-voltage GIS in the power stations is a must. Therefore, the market for gas density monitors is likely to expand with stimulating demand for HV-Gas Insulated switchgear owing to continuous investment in infrastructural development.

Possible Restraint: Distorted readings in partially indoor/outdoor compartments owing to the axial temperature gradient

Some GIS compartments feed through the structure's exterior walls, making them partially indoors and outdoors. This creates an axial temperature gradient or variation in temperature along the compartment's axis. Axial temperature gradients lead to density gradients, which alter readings from pressure/temperature sensor combos and genuine gas density sensors and result in information loss. Since the lost data can only be recovered with additional and prohibitively expensive sensing sites on the same compartment, a more considerable error margin must be anticipated for these compartments. These elements could limit the industry's growth over the forecasted years.

Growth Opportunity: Online Monitoring System for SF6 Gas Density

With digital SF6 gas density online monitoring devices, operator identification skills can be enhanced, and real-time information about substation equipment performance and safe production can be fetched while significantly reducing staff workload. In addition, it can serve as the foundation for high-voltage equipment maintenance and condition monitoring to satisfy the demands of smart grid development. Further, the remote transmission type SF6 relay can monitor the operational state of high-voltage equipment like high voltage gas insulated switch gear, besides maintaining the original SF6 gas alarm and blocking contact capabilities. Consequently, the advent of an online monitoring system presents remunerative opportunities for the industry.

Market Segmentation

Based on End Users,

• Commercial
• Utilities (Power Distribution, Power Generation Utilities)
• Industrial
• Residential
• Transportation (Railways Metro, etc.)

The Power Distribution Utilities segment has seen modest growth in the historical period with the increased focus on electricity generation & transmission with the year-on-year increase in the demand for electricity globally. In addition, the increasing adoption of renewal energy sources for power generation makes it necessary to upgrade the current infrastructure to allow easy integration of the electricity generated from renewable sources.

Therefore, developing economies such as India, China, and Japan aim to achieve 100% electrification and, as a result, are working extensively toward expanding the current infrastructure. These factors are expected to boost the growth of power distribution utilities. Subsequently, the growing HVGIS integration across these power distribution networks has necessitated more robust gas monitoring systems, propelling the industry further in the forecast period.

Based on Product Type,

• Hybrid Gas Density Monitor
• Mechanically Gas Density Monitor
• Electronic Gas Density Monitor

Here, Hybrid Gas Density Monitors have gained popularity over the past few years. It is primarily because hybrid ones’ exhibit added advantage of both the mechanical gas density monitor and the electronic gas density sensor to provide a small, all-in-one device. It is perfect for insulating gas management trending systems due to its continuous measurement output, but it also offers a local gas pressure indication and reliable switchpoint alarm connections. Backed by such benefits, the hybrid gas density monitors are anticipated to drive the industry further in the forecast years.

Regional Projection

Geographically, the Global Gas Density Monitors in High Voltage Gas Insulated Switch Gear Market expands across:

• North America
• South America
• Europe
• Middle East & Africa
• Asia-Pacific

Asia-Pacific, owing to the increasing demand for electricity, impacting the growth of gas-insulated switchgear, is projected to attain a sizable market share in the forecast period. In addition, the upgradation of super substations across Asia-Pacific is required to fulfill the intensifying electricity need; thus, switchgear demand is augmenting in order to maintain & ensure a reliable power supply. With the increasing adoption of switchgear, analog gas-density transducer-based gas-density monitoring systems are gaining popularity lately. Along with constant measurements of the gas densities in all GIS gas compartments, these systems also give the user an estimate of the time it will take for the warning and alarm levels to be reached based on the current leak rate. Backed by such benefits of gas density monitors, the industry is anticipated to rise in the coming years.

Recent Developments

• In 2021, ABB announced the launch of its 420 kV high voltage hybrid switchgear, covering the offering range and reinforcing its technology leadership. The new product belongs to ABB’s PASS (Plug and Switch System) family of hybrid high-voltage switchgear.
