• (1) Maximum discharge voltage for an impulse current wave which produces a voltage wave cresting in 0.5 μs. Discharge Currents are 10kA for 42 - 353kV MCOV. 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 88kV MCOV and a 1000A surge of 45 μs to crest through 190kV MCOV and 2000A through 353kV MCOV.
• (3) TOV Capablility is based on No Prior Duty.
