[THETA] is the fraction of the system cable length actually examined for leakage sources and is equal to the strand kilometers (strand miles) of plant tested divided by the total strand kilometers (strand miles) in the plant;
Ei is the electric field strength in microvolts per meter ([MICRO]V/m) measured 3 meters from the leak i; and
n is the number of leaks found of field strength equal to or greater than 50 [MICRO]V/m measured pursuant to § 76.609(h) .
The sum is carried over all leaks i detected in the cable examined; or
