Current through Register Vol. 50, page 114, March 25, 2024
The person analyzing the data collected examines the data recorded for the 48 hour test and determines the highest steady-state value of cow contact voltage or cow contact current. The person determines the value of primary neutral to reference voltage that was present for the highest cow contact value. These values are identified as cow contact voltage or cow contact current and primary neutral to reference voltage at time of maximum cow contact voltage or current. These values are recorded as Vcc48 hr, Icc48 hr, or Vp48 hr. The three data sets created from the values are:
(1) The primary to reference ground voltage and the cow contact voltage or cow contact current measured during the load box test with the farm power "off" and the load box "off" are recorded as Vp OFF and either Vcc OFF or Ice OFF;
(2) The primary to reference ground voltage and the cow contact voltage or cow contact current measured with the load box set at one-half load are recorded as Vp HALF LOAD and either Vcc HALF LOAD or Ice HALF LOAD; and
(3) The primary to reference ground voltage and the cow contact voltage or current measured with the load box at maximum are recorded as Vp FULL LOAD and either Vcc FULL LOAD or Ice FULL LOAD.
