For the secondary neutral voltage drop test, the three voltages (cow contact voltage, primary neutral to reference voltage, and secondary neutral to reference voltage) are measured with the proxy load "off" and "on." Calculated expected voltage drops are compared with measured voltage drops. If the measured and calculated voltage drops differ significantly, further investigation must be undertaken to determine the source of additional voltage drop within the circuit. Neutral current is measured and recorded with the proxy load "on."
