67 The purpose of testing is to show that the electrical life of the turn insulation provides a life in

68 service which is acceptable to the customer. It is expected that the manufacturer will know the

69 maximum peak to peak voltage to appear between turns in a particular service application. The

70 worst case insulation stress (depending on winding and coil design) shall be chosen. If the

71 maximum peak to peak voltage between turns in service U is unknown, it shall be assumed that

turn

72 the complete jump voltage falls across the first coil and so the amplitude of U is the jump voltage

turn

73 divided by the number of turns (for one layer coils) or calculated according to the arrangement of

74 turns (for multilayer coils). The peak-peak turn-turn voltage is than normally twice the amplitude –

75 as the rise time and the fall time of the jumps is usually the same.
