PQR

01. PQR

Forms reference potential and equipotential to prevent electric shock accidents and Arc, and protect electric devices

  • 70~80% of recent lightning is multiple lightning

    3~4 lightnings per second instantly along the discharge path

  • More and more IC chips are used in advanced digital system

    88.3% of electronic equipment due to unknown cause occurs due to lightning surge (EEE: Electrical and Electronics Engineers)

  • Operation of network, digital/electronic information & communication facility

    Reference potential (neutral line), TN common ground important

  • Electronic facility damage is caused by indirect lightning

    Lightning damages are not direct lightning but reverse surge and EPR

  • N-G, rail potential difference, effect of advanced IC chip operation, electric shock

    `

    Electric shock accident, data processing error, communication error and distortion

Human and equipment protection product through equipotential by solving the potential difference issue based on PQRT ground method

02. Key components

04. Installation diagram

Product is connected in series between rail(+) and PSD(ground,-) as seen in the figure. Models that do not use separate power are installed easily as seen in the figure. Based on this, the system can be configured with various options such as vehicle entry detection sensor, AC220V input, remote control, monitoring, etc.
