• (1) Maximum discharge voltage for a 10 kA impulse current wave which produces a voltage wave cresting in 0.5 µs. This can be used for coordination where front-of-wave sparkover formerly was used.
• (2) Discharge voltages are based on a 500A surge of 45 µs time to crest through 88 kV MCOV and 1,000A surge of 45 µs time through 190 kV MCOV and 2,000A through 353 kV MCOV.
• (3) TOV Capablility is based on No Prior Duty.
• These arresters are typically applied to system voltages of 69 kV and above where the energy requirements are higher than required for lower voltage systems. If a higher energy rated arrester is required for a lower system voltage, Hubbell Power Systems can provide these. Please contact your local representative for more information.
