Calculation of loss with existing equipment

Approximately 10%p higher on overall efficiency compared to existing equipment

➞ Difference in annual loss electricity cost

10 KVA × 0.9 (load power factor) × (0.95-0.85) × 24H × 365 days × 92 won (KW) = 725,327 won
KRW 3.6 billion annually based on 5,000 compact-sized equipment in Korea (power consumption: 39,420 MW)
