Good Voltage is Good Business !!!
"Optimum voltage stability leads to maximum efficiency and innovative energy saving"

Solution with Real-Time Voltage Adjustment

When “real-time intelligent voltage-controlling transformer” which resolves the voltage instability problem, is adopted,
it makes voltage to be stable, efficiency to be improved, loss to be diminished and electricity cost to be lower.

Arc Problems

Cause of Arc Creation

Electric Potential Difference creates Arc when tap moves to control voltage under load.
More Arc is created especially when Selector is used for Reverse Change, Coarse Change, and Start-up.

Arc Problems

Arc causes Damaged Insulation, Burn-out, Burned Insulation Oil, Reduced Durability, and shorten Product Life.
