Basic Insulation Level; a reference insulation level expressed as the impulse crest voltage of the nominal 1 2 X 50 microsecond wave This is a measure of the ability of the insulation to withstand very high voltage surges
band interleaved by line A form of data storage in which each record in the file contains a scan line (row) of data for one band All bands of data for a given line are stored consecutively within the file
Basic Insulation Level is a measure of the ability of the insulation system to withstand very high voltage surges For example, a 600 volt class transformer has a 10 KV BIL rating
born Aug. 15, 1904, Grand Island, Neb., U.S. died March 18, 1987, New York, N.Y. born Jan. 26, 1912, New York City died Dec. 6, 1967, New York City U.S. puppeteers. Bil Baird (originally William Britton Baird) worked under the puppeteer Tony Sarg for five years then produced his own puppet shows from the mid 1930s. He and Cora Eisenberg married in 1937 and began to create original puppets, scenery, and music for their shows. They produced a series of television shows in the 1950s and opened their own marionette theatre in New York in 1966. Bil wrote The Art of the Puppet (1965) and trained puppeteers such as Jim Henson

The basic impulse level or basic insulation level To meet a given BIL rating a bushing must be able to withstand a simulated lightning wave that has a wave shape of 1 2 by 50 microseconds and in both positive and negative polarities The wave reaches its peak in 1 2 microseconds and decays to ½ of the peak value in 50 microseconds BIL ratings are expressed in KV (kilovolts)
