ENERGY MAINTENANCE TECHNOLOGIES LTD (EMT)

The ZWR+ is 5 times more productive than any standard measurement of SF6 gas purity in gas insulated switchgear and high voltage equipment. Delivering laboratory-standard accuracy, stability and repeatability in the field: the ZWR+ provides automatic, multi-analysis gas quality testing using advanced IR measurement technology for the fastest and simplest, zero-emission measurement solution in GIS preventative maintenance.

Preparation is key when it comes to SF6 gas analysis. Ensuring the analyser is within calibration is fundamental to safe operation, compliant measurement and accurate testing. Our Verify NIST traceable verification gases can prove the instrument is in specification and valid for use in accordance with ISO9001 requirements for controlled measurement equipment. EMT SF6 gas verification products utilised during operation provide continued assurance that the analyser is performing as it should be, that the measurements shown are accurate, and that these are in line with the measurement values and tolerances of the supplied gas.

Used widely in electricity substation maintenance, Smartfill provides a simple, efficient, zero emission alternative to manual filling and top-up of SF6 compartments. Filling of newly installed SF6 assets and refilling of in-service assets can be achieved automatically during live energised operations. Topping up leaking or damaged SF6 assets can also be completed without an engineer. Designed to accurately measure, control and monitor SF6 gas passing through the network, this smart solution delivers compliant measurement of SF6 inventory and usage with complete traceability.

With any filling device, a range of accessories can help produce a more efficient fill during maintenance tasks. EMT can supply a range of heated blankets and regulators to ensure if manually filling, the chances of a line freeze are reduced. Typically 20-25% of SF6 is wasted due to temperatures and pressures keeping the SF6 liquified. Our cylinder heater blankets evaporate the gas, increasing the efficiency of the cylinder, to ensure the maximum amount of SF6 can be recovered. This amounts to significant savings on maintenance costs.

Utilities personnel working on Gas Insulated Switchgear are in danger from exposure to SF6 gas leaks. Colourless and odourless, SF6 can accumulate undetected, presenting serious health and environmental risk. The EMT GasSafe Gas Leak Detection System offers a feature packed solution to monitoring real time gas leaks from electrical equipment or potential other unsafe gaseous emissions. Our gas safety system provides rapid detection, immediate response and early warning in the event of gas leaks or an unsafe working environment, ensuring personnel safety and asset protection. Ideal for traditional SF6 and new SF6 alternative gas installations. Provides an intelligent and comprehensive solution to your SF6 F-Gas leak detection requirements. Measurement of over 400 different gases and vapours from ppm to %Vol. Easily add or remove sensors and accessories as your system needs grow with up to 128 detectors on a single control panel.

Leaking assets present challenges for utilities trying to keep their plant operational. Our unique leak management system is a live continuous SF6 topping up device, which provides automated, on-demand top-up capabilities in the event of a leak. The Smartfill CTU 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. Designed to be left in the field for extended periods of time this smart solution provides safe and secure operation via remote access, SMS technology and traffic light warning system. All data is stored within the unit and operators are only required to attend site if alerted of any issues. Where GIS performance may be affected by depleted SF6, Smartfill technology secures continuity for Transmission Network Operators, offering the most effective solution for leaking assets.

Providing a reliable resource and expertise to clients in the utilities sector, EMT Site Services use a range of technologies and solutions to deliver key environmental and financial benefits including: asset reliability, long term compliance and performance, maximum up-time and security of critical infrastructure. Service provision includes: Flange Repairs; SF6 Leak Surveys; Corrosion Prevention; Rental/Lease SF6 Instruments; SF6 Filling and Topping Up; Gas Recycling; Protective Coatings, Training.

Moisture levels in dry air, SF6 or alternative gas assets can lead to potential catastrophic failure and reduced asset life. EMT Moisture Pro is a fast, portable, accurate, smart dew meter for moisture determination in critical assets.

Adoption of SF6 alternative gases increases the maintenance and analysis burden on utility staff, requiring multiple analysers to fulfil test and analysis procedures. This requires increased levels of capital budget; increased time to undertake maintenance tasks; resulting in greater inefficiencies onsite. The EMT Zerowaste Rapide Eco+ solves this problem by fulfilling all measurement requirements in one, simple, portable device. Built on the existing market leading EMT Rapide+ platform, Eco+ is the world’s first 4in1 analyser for the measurement of SF6, Novec 4710, Novec 5110 and Dry Air insulating gas applications.

The leakage of insulating gases from GIS, switchgear and other compartments is a global issue. Insulating gas leaks present a major problem to utility companies: •Reducing plant efficiency, causing damage to assets or outages •Costing money through fines or legislative punishments •Exposure of employees to toxic gases Utilising Infrared detection technology the EMT Leak Hunter enables fast leak detection on gas insulated compartments containing SF6 or Eco based insulating gases; one instrument … two jobs. •Reduce the rate of gas loss •Find leaks fast for early intervention •Ensure user safety from leaking potentially harmful gases •Comply to existing and new regulations •Reduce costs associated with gas usage and topping up •Reduce costs associated with regulatory body fines •Reduce CO2 footprint
