Abstract

A submersible current sensor for sensing a current in a submerged conductor includes: a split core current transformer constructed to generate an output representative of the current carried by the conductor, the split core having a first core member, a first winding disposed about at least a portion of the first core member; a second core member; and a second winding disposed about at least a portion of the second core member; and a housing, the housing including: a first housing member constructed to house the first core member and the first winding; and a second housing member constructed to house the second core member and the second winding.

First claim

1 - 11 . (canceled)

12 . A submersible current transformer (CT) sensor, comprising:
a polymer housing, including:
a first polymer housing member with a first transformer part hermetically sealed therein, wherein the first transformer part includes a first core member and a first winding disposed about at least a portion of the first core member; and
a second polymer housing member with a second transformer part hermetically sealed therein, wherein the second transformer part includes a second core member and a second winding disposed about at least a portion the second core member; and
a cable coupled to the first transformer part and the second transformer part, wherein a first portion of the cable is sealed within the first polymer housing member and a second portion of the cable is sealed within the second polymer housing.

13 . The submersible CT sensor of claim 12 , further comprising a waterproof resin, wherein the first transformer part is encapsulated by the waterproof resin and hermetically sealed in the first polymer housing member with the waterproof resin; and wherein the second transformer part is encapsulated by the waterproof resin and hermetically sealed in the second polymer housing member with the waterproof resin. Preliminary Amendment

14 . The submersible CT sensor of claim 12 , further comprising a hinge coupling the first polymer housing member to the second polymer housing member.

15 . The submersible CT sensor of claim 14 , wherein the hinge is integral with the polymer housing.

16 . The submersible CT sensor of claim 12 , further comprising a latch constructed to latch the first polymer housing member to the second polymer housing member.

17 . The submersible CT sensor of claim 16 , wherein the latch includes a first polymer latch member that is integral with the first polymer housing member, and a second polymer latch member that is integral with the second polymer housing member.

18 . A submersible housing for a current transformer (CT) sensor, comprising:
a first polymer housing member constructed to house: a first split core current transformer part; and a first waterproof resin that encapsulates the first split core transformer part and hermetically seals the first split core current transformer part in the first polymer housing member; a second polymer housing member constructed to house: a second split core current transformer part; and a second waterproof resin that encapsulates the second split core transformer part and hermetically seals the second split core current transformer part in the second polymer housing; a hinge constructed to pivotably couple the first polymer housing member to the second polymer housing member at a first end of the housing; and a latch constructed to releasably attach the first polymer housing member to the second polymer housing member.

19 . The submersible housing of claim 18 , wherein the hinge is a polymer hinge integral with the submersible housing.

20 . The submersible housing of claim 19 , wherein the latch includes a first polymer latch member that is integral with the first polymer housing member, and a second polymer latch member that is integral with the second polymer housing member. Preliminary Amendment
