Application No. 09/289,076
The invention includes a transformer and an amplifier. In turn, the transformer
comprises a primary wire and a secondary winding. For its part, the primary wire
carries a leakage current from an insulator for a high voltage conductor to ground. The
amplifier has two input terminals connected across the secondary winding of the
transformer and produces an output signal proportional to the leakage current. (Id.
at 1-2.)
A further understanding of the invention can be achieved by reading the following
claim.
1. Apparatus for monitoring leakage currents from an insulator for
a high voltage conductor to ground comprising:
a transformer comprising a primary wire and a secondary winding,
the secondary winding having a secondary resistance, the primary
wire constructed and arranged to carry a leakage current from the
insulator to the ground; and
an amplifier having an input connected to the secondary winding,
constructed and arranged to produce an output signal proportional to the
leakage current.
Claims 1 and 4 stand rejected under 35 U.S.C. § 102(b) as anticipated by U.S.
Patent No. 5,652,521 (“Meyer”). Claims 2, 3, and 5-24 stand rejected under 35 U.S.C.
§ 103(a) as obvious over Meyer and U.S. Patent No. 3,881,149 (“Kiko”).
