Current through Register Vol. 50, page 114, March 25, 2024
A digitizing data recorder with averaging capability and capable of detecting and recording transient deviations of one-tenth of a second or less in duration is used to record the following:
(1) Voltage from primary neutral at the transformer to remote reference electrode;
(2) Voltage from secondary neutral in the service panel serving the area of the cow contact to remote reference electrode;
(3) Voltage from primary neutral at the transformer to secondary neutral at the service panel serving the area of cow contact; and
(4) Cow contact current through or voltage across a shunt resistor at each high voltage point found in the cow contact test.
A recording interval as high as ten seconds may be used provided that transient deviations of voltage or current of one-tenth second or less in duration of voltage or current are recorded to the maximum ability of the instrument.
