Tan Delta Tester

TAN DELTA SYSTEM SA-188 is specially designed for quality control of enamelled wire. Tangent delta and the tangent data temperature characteristic are the concepts often discussed in connection with enamelled copper wire.

The precise measurement of tangent delta is of higher importance for the characterization of hardening state of the enamelled insulation. If an alternating voltage is applied to wire enamel, a small current passes through it which is phase shifted. A yard stick for this phase shift is tangent delta. Measuring frequency of 1 KHz sine voltage is applied to the sample. The results phase shift between voltage and current which is proportional to tangent delta. This phase shift is detected with very precise phase detector circuit.

SA-188 can be used for single point measurement as well as determinations of bending point. The temperature can be set anywhere up to 300 degrees Celsius for single point measurement. Tan delta and temperature are displayed simultaneously. Curve measurement can be automated on PC through suitable windows-based software.
