PD monitoring diagnosis technology of ESS Switchgear
When a partial discharge occurs in the ESS switchgear, a partial discharge is detected by raising the transient earth voltage caused by UHF in the grounded metal clad portion, thereby preventing insulation deterioration

arc fire monitoring technology in battery rack
UVTRON is applied to detect ultraviolet rays by arc fire in the battery rack → “Detecting arc fires by detecting an ultraviolet rays of 185~260nm wavelength band"
PCS technology for Electricity quality improvement
· G2POWER’s ESS can provide stability to PCS by minimizing the voltage fluctuation generated during mode switching ,and can supply stable power
  to the load
· Improving an effect of noise, leakage current, surge, noise, etc. generated from PCS through 3 level topology design
Current wave before the improvement
Current wave after the improvement
