SVG and AHF maintenance is the scheduled inspection, measurement and component-replacement programme that keeps a static var generator (SVG) and an active harmonic filter (AHF) inside their design limits — stable reactive power compensation, a corrected power factor, and harmonic current below the limits agreed at the point of common coupling (PCC). Most plants do not lose power quality equi...
Why a Solar Plant Needs Active Compensation A Static Var Generator (SVG) is an active, IGBT-based power-electronics compensator that stabilises voltage, supplies or absorbs reactive power and filters harmonic current at the point of common coupling (PCC) of a solar plant. It turns unstable PV output into grid-compliant power for EPC contractors, electrical engineers, procurement teams and power-qu...
When Power Quality Equipment Must Also Be Quiet A Static Var Generator is normally evaluated by reactive power capacity, response time, power factor control and harmonic compensation. In many installations, the equipment room adds another requirement: the solution must also control noise, dust exposure and maintenance demands. YT Electric’s Fanless Static Var Generator uses natural he...
A 1,000 kVA transformer feeding six-pulse VFDs, spot welders and single-phase loads is a textbook harmonic source. Field measurements on such busbars typically show current THD of 25–40 % at the PCC, with the 5th and 7th orders dominant. Third-order currents add up in the neutral conductor and overheat it. Fixed capacitor banks rarely survive this environment. When the natural resonan...
Can Poor Power Quality Increase Your Electricity Bill? When an electricity bill rises, businesses usually examine production hours, electricity prices, and new equipment. But poor power quality can also raise costs by increasing current, creating losses, reducing efficiency, and triggering demand or power-factor charges. The effect depends on the utility tariff, load types, and metering method. It...
