Smartfill CTU Installation for Middle Eastern Utility

EMT Site Services have recently completed on site installation of 4x Smartfill Continuous Topping Up Systems, for a leading Electricity Transmission and Distribution Network Operator, in the Middle East.

The Smartfill CTU delivers live, automated, on-demand top-up in the event of an SF6 leak; and is designed to manage leak operations where regular, controlled top-ups are required. Using this zero-waste approach to replenish the gas results in reduced SF6 usage, inventory and costs.

Smartfill technology ensures assets remain operational and at peak performance, securing continuity for EMT customers. The team reports the installation was a success, as was the training which followed, and that discussions are underway for further installations on other sites.

SF6 leak repair on vertical flange under live conditions and pressure/outage

Industry: Power T&D

Application: SF6 Leaking Vertical Flange x 3

Customer: UK Electric Utility Substation

Date: April 2022

Problem: To fix three identified leaking/potentially leaking flanges on SF6 substation site

Solution: Vertical REFLANGEKiT® SF6 leak sealing. Flanges repaired under live conditions and pressure/outage

Works:

  • Leak surveyed/identified using EMT SF6 leak detector
  • Environmental/climatic conditions surveyed and approved
  • Surface preparation works undertaken
  • Cleaning and degreasing of surfaces carried out
  • Phase one flange repair –  soft shell mounting completed; the purpose of the soft shell is to protect the functional parts of the flange i.e. bolts and seals, and to concentrate the leaked SF6 gas to a single point of the shell where the valve is located. This was followed by re-enforcement of the soft shell
  • Phase two flange repair –  hard shell and resin application completed; resin was injected into the hard shell and left to cure overnight
  • Sleeve removed, valve sealed, and leak test undertaken using EMT SF6 calibrated leak detector, concluded with final seal and post repair testing

SF6 Gas Leak Repair with EMT

Industry: Power T&D

Application: SF6 Leaking Flange

Customer: UK Electric Utility

Date: December 2021

 

Solution: REFLANGEKiT® SF6 leak sealing technique

 

Technology: The 3X ReflangeKit® concept is based on a composite double shell system that encapsulates the leaking flange. The first shell covers and protects the flange collecting SF6 leaks. The second shell contains specific resin. An exhaust valve allows the SF6 gas to escape during resin injection. After overnight curing of the resin, the valve is closed and sealed giving a 100% seal and leak free composite repair.

 

Benefits: The installation was non-invasive and did not require a power outage. Repair was completed online and under pressure. Disassembly was easy, the fix was efficient, and cost effective.

 

Deliverables: Shunts, bolt heads and flange seals are now protected. The completed repair was tested and successful – further repairs are scheduled. Another satisfied customer, and another testimonial for EMT Site Services.

SF6 leak detection, management and repair – maintaining, managing and mitigating SF6 leaks

The Issue

SF6 is a global warming gas and the leakage of process gases and liquids from compartments is a global issue. Leakage of SF6 is more than an internal concern and is now a broader ethical obligation, as utility companies commit to carbon neutrality by 2050. As a requirement to report loss rates in line with permitted release rates, leakage of SF6 gas is highly detrimental to achieving this goal. Therefore utilities need an effective preventative maintenance plan for assets to remain operational and to ensure business continuity.

 

The Task

Reduce the rate of SF6 loss

Reduce costs associated with gas usage and topping up

Reduce costs associated with regulatory body fines

Reduce CO2 footprint

 

…detection, measurement and repair of SF6 leaks
