Energy, Fast!

2 145kV Compact GIS Substation www.tgood.com

TGOOD engineers set out to create a better urban substation, patenting 38 features that combine to create a next generation solution for modern cities and industrial sites around the globe.

Increased urbanization and growing demand for electricity necessitates new substation construction in congested built-up areas.

Traditional substations create fears of noise and radiation and may be prone to vandalism.

Traditional substations require a footprint of up to 3300m2 and require at least 18 months to construct, straining scarce land resources and subjecting the area to expensive and unsightly construction projects.

PRODUCT CONCEPT

The TGOOD 145kV Compact GIS Substation reduces construction times to between 3 and 6 months and uses only 20% of the space required by a traditional substation

3145kV Compact GIS Substationwww.tgood.com

KEY BENEFITS

SPEED

Compared to traditional substations, construction times are reduced to between 3 and 6 months and commissioning times are reduced to just one month or less.

SAFETY AND APPEARANCE

Acoustic and electromagnetic shielding reduce noise and radiation for safe and silent operation (below 40dB). E-House enclosures are safe to touch and provide exceptional protection against vandalism. Custom paint work helps the station blend in with surroundings.

SPACE SAVINGS

Compact substations reduce the land space required to as little as 420m2, conserving valuable land in congested urban and industrial areas.

REACTIVE POWER COMPENSATION MODULE

Substation power-factor correction and/or harmonic filtering may be included as a module.

Capacitor banks may be tuned or detuned as required for the application.

Fixed or variable stages of compensation available.

NEUTRAL GROUNDING MODULE

Customers may choose between solid grounding, resistive grounding, reactor grounding or resonant (Peterson coil) grounding.

CLIMATE CONTROL AND ALARM SYSTEMS

System guarantees ideal environment for reliable operation and long lifespan of electrical components.

Patented positive-pressure and air conditioning system provide a constant temperature and constant humidity, dust-free operating environment.

Positive pressure environmental control system ensures that internal cabin pressure is always greater than external atmospheric pressure (typically 105%) to repel dust. This technology has been tested and proven in the world’s harshest operating environments, including the world’s highest railway in Tibet.

Alarm system detects deviations from standard operating tolerances to ensure safe and reliable operation.

Early warning fire alarm is calibrated to detect a fire hazard hours before visible smoke is produced while eliminating the risk of false positives.

Climate control system utilizes a heat pump to precisely control the cabin temperature and humidity at all times.
