•
The three-phase, four-wire SVG is applicable to the power grid system with neutral
grounding.
•
The CT wire shall be fastened to avoid open circuit, which will lead to high-voltage risk
and secondary circuit burning.
1.3 Usage
Warnings
•
Only qualified service personnel can update SVG hardware and firmware.
•
Since the SVG is used for reactive power and imbalance compensation of the power
grid, the capacity selection of the SVG shall be subject to reactive power and imbalance
content to avoid poor compensation due to insufficient capacity.
•
Before installation, wiring and working on the SVG’s internal circuits, please completely
cut off all power supplying to the SVG.
•
Since SVG is used for reactive power mitigation, external CT shall be connected to
detect the reactive current.
•
To guarantee sound reliability and avoid overheating, do not block or cover the air inlet
and outlet.
•
The thermal loss of Mixed Fixed type SVG is not bigger than 3% of rated apparent
power.
•
The operating environment temperature of SVG shall be between -10°C (14°F) and
55°C (131°F). The relative humidity shall be within 95% (non-condensing). For detailed
derating information, please refer to
2.3 Functions & Features
.
•
The SVG system shall be installed at a place with altitude less or equal to 1000 m
(3280 ft). Derating 1% per 100 m (328 ft) when the altitude is between 1000 m and
3000 m (3280 ft ~ 9842 ft). For more question, please consult Delta or Delta distributor.
