Typically, the failure is abrupt and is observed as a sudden, dramatic . The purpose of the dielectric withstand (hi-pot) test is to determine whether the insulation from the primary circuit to grounded or accessible parts has sufficient electric strength to withstand the normal overvoltages which could occur in service. We always had to do these with a CPVC penetration. ). %PDF-1.5 % If the length of metal conduit entering the facility prior to transitioning to the PVC break is as long or longer than the wavelengths we are interested in picking up, then we will have an unimpeded pick up and reception of that wavelength and frequency.
