Triad isolation transformers are power transformers for isolating
equipment from direct connection to the power line. They are offered
in a variety of voltages and case types. Triad isolation transformers
are also offered in hospital type (designed with an MD suffix) which
are designed and constructed to meet the low leakage current
requirements for today’s medical equipment. The transformers are
constructed with nonconcentrically wound coils. The primary and
secondary are wound on separate arbors, then assembled on a
laminate core side-by-side separated by insulation. This prevents
