Smartfill CTU Installation for Middle Eastern Utility

Post author By Lisa Redmond
Post date March 29, 2023

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 site survey, flange repair, leak management – job done with EMT Site Services

They say pictures speak a thousand words; here’s our latest Site Services project completed for a UK electric utility. Following a site survey, the team confirmed SF6 leaks on all phases of the asset, which required immediate repair and preventative maintenance. The project was for x6 flange repairs; x3 upper flange and x3 lower cover plate with sensor. All repairs were carried out under live conditions and full pressure. From surface preparations; to soft shell mounting and reinforcement; through to hard shell, resin application, final seal and post repair testing – our expert engineers followed proven and rigorous EMT protocols using trusted and reliable EMT technologies and solutions, to ensure compliance at every stage of the project.

EMT Site Services deliver another successful project for a UK Solar Farm

Post author By Lisa Redmond
Post date October 31, 2022

Industry: Solar Power Generation

Application: GIS analysis and topping up

Customer: UK Solar Farm

Date: October 2022

Problem: Leaking asset

Solution: SF6 leak detection, analysis and top up delivered by EMT Site Services utilising EMT SF6 management products

Works:

Site survey detected and located switchgear leak using EMT Handheld SF6 Leak Detector
Gas analysis carried out by EMT Site Service Engineers using EMT Zerowaste Rapide+ Analyser
Tests prior to gas top up indicated SF6 gas required
Tests after the asset was re-gassed confirmed SF6 gas usage
Asset checked for leaks following gas top up and minor repairs

Result: Leak detected at another location; further works required by EMT Site Services

Survey and repair leaking SF6 assets cost effectively and with minimal disruption to operations

Post author By Lisa Redmond
Post date September 21, 2022

EMT delivered the technology and expertise to survey and repair leaking SF6 assets with a cost-effective solution and minimal disruption to operations, which was welcomed by the customer, whose alternative would have been to replace the asset at considerable cost and with significant disruption to the substation – another job well done by the EMT Site Services Team.

Industry: Power T&D

Application: SF6 gas inspection cover plate repairs

Customer: UK electric utility substation

Date: August 2022

Problem: Leaking SF6 gas on cover plates

Solution: SF6 leak repair to inspection plates – non pressurised. 9 repairs completed

Works:

Leak surveyed by EMT Site Services team using EMT Handheld SF6 Leak Detector
Existing gas purity analysed with EMT Zerowaste Rapide+ Analyser
Asset de-gassed using EMT Gas Cart
Surface preparation and cleaning works undertaken
Specialist repair works completed
Asset re-gassed, gas purity checked, and post repair testing completed
Further scheduled preventative maintenance work has been recommended by EMT Site Services due to high H20 ppm readings recorded in the SF6 gas

Field based SF6 gas top up utilising EMT Site Services and patented EMT Smartfill technology

Post author By Lisa Redmond
Post date June 29, 2022

EMT Site Services can top up your SF6 assets – contact the team to see how we can provide both the test equipment, and trained and certified SF6 gas technicians, for the safe filling and topping up of SF6 compartments. Performing these essential tasks, our Site Services team can provide 24/7 coverage across the network, supported by tailored service packages to suit specific gas handling requirements, and complimented with a range of SF6 gas management services.

Our team have recently completed work on two sites for a UK utility:

Industry: Solar Power Generation

Application: SF6 Gas Topping Up x 2 Sites

Customer: UK Solar Farm

Date: June 2022

Problem: Low gas pressure reported

Solution: Field based SF6 gas top up utilising EMT Site Services and patented EMT Smartfill technology

Works:

Leak survey completed using EMT SF6 leak detector
Pressure survey completed
SF6 gas top up completed
Continued pressure monitoring advised
Future repair, de-gassing and re-gassing works discussed

Deliverables: SF6 gas top up restored pressure to normal operating conditions. The client was satisfied, particularly given there were challenges sourcing the correct fittings to carry out the works – EMT took care of all requirements from initial surveillance, to sourcing bespoke fittings for connection, and topping up of the SF6 compartments

SF6 Leak Management

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

Post author By Lisa Redmond
Post date June 29, 2022

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

Online Repair for SF6 Leaking Flange

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.
