High Voltage Inc. Provides Portable Testing Equipment for Wind Farms

hvi_scotland.jpgAugust 24, 2009, COPAKE, NY -- High Voltage, Inc. serves the wind industry by providing portable VLF .1Hz Very Low Frequency AC hipots and AC HV Test equipment for proof testing the medium voltage collector cable circuits and switchgear commonly used on wind farms. The VLF .1Hz testing of wind farm power cable feeders and collector cable circuits per IEEE- 400.2 is a simple, cost effective, and conclusive quality assurance test method.

It definitively proves out the integrity of the workmanship, cable insulation and its associated accessories such as splices and joints. A VLF AC withstand test is an excellent test method for insuring the cable laying

and workmanship of the new installation is good and will provide reliable,

long-term power distribution to the distribution grid the wind farm serves.

High Voltage, Inc. also can supplement VLF withstand testing with Tan delta

testing diagnostics via a Tan delta bridge used in conjunction with a VLF AC

Hipot. By monitoring the tan delta readings of a cable circuit over time,

one can determine if a particular cable is beginning to show insulation

degradation commonly caused by water trees possibly leading to a cable fault disrupting power delivery. By discovering a suspect cable before a

catastrophic cable fault, plans can be made ahead of time to repair,

rejuvenate or replace the cable and splices during a controlled repair

outage minimizing power interruption and service failure.

These two testing methods (VLF & Tan delta) are the easiest, most time

proven, simple, and conclusive for wind farm managers and HV contractors to enhance and continuously provide a reliable installation and reliable

generation of power. High Voltage, Inc. is very familiar with all cable

testing technologies, and knows cables.
