IN-SITU DATA ACQUISITION SYSTEMS AND METHODS
First Claim
1. A method for acquiring one or more discharge events from a power system having a plurality of power cables supplying power to a plurality of loads, the method comprising:
- detecting signals associated with power components of the power system with a plurality of sensors, the signals including power and one or more of noise and discharge, wherein the plurality of sensors are permanently associated with the power system;
transmitting the signals to a location separate from the power system;
storing the signals as test data onto a removable computer storage media at the location.

Abstract
Data acquisition systems and methods for acquiring test data associated with standard insulated power cables and/or power equipment such as switchgears, transformers, electric motors, etc are disclosed. The test data may then be subsequently analyzed for defects, such as the presence of faults, discharges (e.g., PD, coronas, arcing, etc.). The systems may store the acquired test data on removable, non volatile memory, such as Flash memory. The removable memory may be retrieved by an un-skilled technician periodically and returned to a lab or other test facility for subsequent analysis by highly trained analysts.
