Q2 An industrial plant is served by a 12470V delta / 480 V grounded -wye transformer . The high voltage side of the

transformer is served from a 12470-VDELTA/480-V wye connected distribution line that has a grounded neutral

.The best protection of the transformer against lighting strikes on the 12,470-v line will result from surge arrester

connections of?

e. Phase to ground on the 12,470-V side of the transformer

f. Phase to phase on the 12,470-V side of the transformer

g. Phase to ground on the 480 V side of the transformer

h. Phase to neutral to ground on the 480-v side of the transformer
