LV Compensation & Filtering Products
Providing Power Quality and Energy Efficiency
Low (LV) reactive power compensation and harmonic filtering solutions help customers to
improve the performance of installations through energy savings and better power quality,
enabling end users to save money and reduce the environmental impact of their
operations.
GE offers compensation equipment, a wide range of products and one-off solutions at low
voltage levels. Specialists analyse the exact needs of the application and engineer the right
solutions for optimal efficiency and economy.

Product Features
QUANGANHCGTE’s power factor controllers provide your network with efficient
reactive power compensation, measurement and supervision.
User-friendliness and Condition Monitoring
User-friendliness due to multilingual user interface, clear text and
symbol messages, graphics, alarm log and communication. GE’s
power factor controller offers advanced condition monitoring for
your network as well as for the capacitor bank. The supervision
and condition monitoring functions add to the simplified
programming with intelligent self-set-up to ensure optimal use of
the reactive power compensation system.

Quotation scope

Applies to one EVN-supplied substation with oil-immersed transformers at 22/0.4 kV (single-phase: 12.7/0.23 kV), with MV metering VTs/CTs supplied by EVN. The estimate includes the selected equipment, installation, earthing, transformer-to-main-breaker connections, design and connection documentation, and coordination of testing and utility acceptance.

Kiosk, integrated steel-pole and indoor substations include MV switchgear and the entered underground cable route. Other outdoor arrangements use the relevant protection configuration. The final diagram must meet the project connection requirements.

Excludes VAT, cables from the substation switchboard to the MSB/loads, live-line work, harmonic reactors, weak-ground treatment or special piling, land and special fire-protection provisions. Underground routes assume normal construction conditions and exclude road drilling and special reinstatement.

Prices are indicative investment budgets. A formal quotation follows site assessment and agreement on the configuration. Electrical selections are preliminary and require design verification before installation.

Capacity range and application conditions

The catalogue defines the enquiry range of this tool, not universal TCVN capacity limits. Single pole-mounted transformers: 15–100 kVA; three-unit banks: 3×15–3×100 kVA. Platform substations: 100–630 kVA. Steel-pole substations: 100–630 kVA; 750/800 kVA require design verification and local approval. Ground-mounted, kiosk and indoor configurations: 50–10,000 kVA. Not every configuration has a package price or the same structural design.

Reference: EVN Decision 1299/QD-EVN dated 3 November 2017, Volume 1, sections 3.3–3.4. Check the current requirements of the responsible utility before implementation. Kiosks must meet manufacturer ratings and testing requirements (IEC 62271-202); indoor and ground-mounted arrangements must meet project layout, ventilation, structural and fire-protection requirements. For multiple transformers, specify the quantity and capacity of each unit.
