APPLICATIONS

Eco Friendly Power Transmission

In 2021 to reduce global warming world energy reliance has made an irreversible shift towards renewable energy sources such as wind and solar power generation.

 By now the more cost Effective form of switchgear is the  (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF6). Total Switchgear demand in 2020 was US$20 billion and Gas Insulated Switchgear accounted for 16.5 billion and an estimated demand of US$ 26.5 billion for GIS in 2025 due to increased demand in China and India.

Renewable Grid Integration

Increased addition of renewable power, to add more fluctuations to the grids this requiring rapid power cut on/ off.  Standard GIS will have limitations due to their maximum number of operating cycles.

Greater deamand on electrification for industrial processes, electric vehicles and excessive use of large scale renewable energy driven power generation require increased energy storage and will supplement enlargement of power grids with high and ultra-high voltage transmission lines, power stations and associated infrastructure.

Maintenance Free Operations

O&M is a major cost portion, for power utilities. Ever rising power demand, with a retiring workforce,  scarcity of expertise will put pressure on grid operators in search for automated remote controllable circuit breaker designs.

The proposed ISGI is fully automated, remote controllable with on board data logging facility. This will require minimum human supervision and capable of reporting services requirements in advance through on board process analytics.

SOLUTIONS

Retrofits & Upgrades (Brown Field Projects)

Existing GIS installations considered be converted to ISGI supported AIS, This will result minimum modifications for existing installations, thus saving cost and outage time. ISGI Retrofit installations will require less labor ,and maintenance helping utilities who already struggle with limited labor and tightening O&M Budgets

New Designs (Green Field Projects)

It is expected the power transmission sector to expand rapidly while catering rising demands especially in emerging markets. Moreover Smart grids and Renewable integrations & HVDC transmissions will require fast operations of GIS in short periods with multiple operations cycles. These new requirements will place challenges on standard GIS with finite number of starts per certain period of time.
A complete new range of products to be developed with three HV classes, 33kV, 132kV, 400kV and above targeting new installations

THE TECHNOLOGY

The next-generation switchgear will be an arc-free solution, hence eliminating the requirement for an arc quenching SF6 greenhouse gas. This system will utilize the latest linear actuator technology which contains rare earth permanent magnets and avoids the use of a gearbox. This linear actuator technology , has been effectively applied in numerous Aerospace and Defense development programmes in the UK.

The technology is protected with patent, US 2009/0159413.A1, for a High Voltage Switchgear Operating Mechanism, commonly called as the “Interrupter”. Compared to available technologies several advantages are noted.  The ISGI consists of a position controlled high power linear actuator, driven with an precision motor controller.

  1. Will use “Pure Air” as insulator media, thus no need SF6 or other Industrial Gases with additional devices

  2. Tracks “Zero Crossing” contact voltage and engaged at minimum so arcing to be eliminated

  3. Fully remote controllable and be monitored, enhanced with AI

  4. Keeping movable parts to a minimum, with increased reliability
