Claims
- 1. A method for indicating electrical breakdown in a water cooling system for high power electrical equipment, comprising the steps of:
- selecting a plurality of portions of said water cooling system, said plurality of portions having a large electrical potential difference between them, being connected by a column of water, said water having a given resistance value that is nonconductive, connecting a resistor between at least two of said plurality of portions, said resistor having an ohmic value that is small compared to said given resistance value of the water and large enough to produce a recognizable voltage signal when the given resistance value of the water degrades to a conductive state;
- coupling a detector circuit to said resistor, said detector circuit being capable of indicating when said recognizable voltage is present across said resistor; and
- shutting down said high power electrical equipment when said detector circuit indicates said recognizable voltage signal is present across said resistor.
- 2. The method for indicating electrical breakdown in water cooling systems for high power electrical equipment, as recited in claim 1, wherein two of said plurality of portions of the water cooling system selected are a pair of intake pipes.
- 3. The method for indicating electrical breakdown in water cooling systems for high power electrical equipment, as recited in claim 2, wherein said resistor is no greater than one ohm.
- 4. The method for indicating electrical breakdown in water cooling systems for high power electrical equipment, as recited in claim 1, wherein two of said plurality of portions of the water cooling system selected are a pair of output pipes.
- 5. The method for indicating electrical breakdown in water cooling systems for high power electrical equipment, as recited in claim 4, wherein said resistor is no greater than one ohm.
- 6. An apparatus for indicating electrical breakdown in a water cooling system for high power electrical equipment, comprising:
- said water cooling system having a plurality of portions being connected by a column of water, said water having a given resistance value that is nonconductive;
- a resistor connected between at least two of said plurality of portions having a large potential difference between them;
- said resistor having an ohmic value that is small compared to said given resistance value of the water and large enough to produce a recognizable voltage signal when said given resistance value of the water degrades to a conductive state;
- a detector circuit coupled to said resistor, said detector circuit being capable of indicating when said recognizable voltage signal is present across said resistor; and
- a means for shutting down said high power electrical equipment when said detector circuit indicates said recognizable voltage signal across said resistor.
- 7. An apparatus for indicating electrical breakdown in water cooling systems for high power electrical equipment, as recited in claim 6, wherein two of said plurality of portions of the water cooling system are a pair of intake pipes.
- 8. An apparatus for indicating electrical breakdown in water cooling systems for high power electrical equipment, as recited in claim 7, wherein said resistor is no greater than one ohm.
- 9. An apparatus for indicating electrical breakdown in water cooling systems for high power electrical equipment, as recited in claim 6, wherein two of said plurality of portions of the water cooling system are a pair of output pipes.
- 10. An apparatus for indicating electrical breakdown in water cooling systems for high power electrical equipment, as recited in claim 9, wherein said resistor is no greater than one ohm.
