    This voltage applies to all of the load input terminals of the PEL-500 Series when the impedance of the EUT is relatively small. The voltage generated by the load wire inductance (L) and the current variation (I) is expressed using the following equation.
  • Page 71 INSTALLATION In general, the wire inductance can be measured approximately 1 μH per 1 meter. If the 10 meters of Load wires is connected between the EUT and the electronic load (PEL- 500 Series) with the current Variation of 2 A/μs, the voltage generated by the wire inductance Will be 20 V.
