Universal Citation: WI Admin Code ยง PSC 113.0914
Current through August 26, 2024
In this section, "meter" or "meters" may refer to metering system(s).
(1) Polyphase meters used with instrument transformers, together with associated equipment such as demand equipment, pulsing devices, phase-shifting transformers, control devices, etc., shall be tested on the customer's premises, a central testing facility or in a mobile test facility, except for pars. (a) and (d), for accuracy at unity and 50% power factor under the following circumstances.
(a) Before being placed in service. For new
meters given a prior test by the manufacturer, the manufacturer's certified
test results may be substituted for this requirement.
(b) When they are suspected of being
inaccurate or damaged.
(c) When the
accuracy is questioned by a customer. (See s.
PSC 113.0922.)
(d) When they are removed from
service.
(e) Within a period of 4
months before or 4 months after 2 years of service for non-magnetic-bearing
electromechanical meters, 4 years of service for electromechanical
magnetic-bearing surge-proof meters and 6 years of service for completely solid
state electronic meters with electronic registers capable of down-loading
voltage and current monitoring readings from the instrument transformers to
digital meter reading devices at meter reading intervals. Exception: Electronic
(solid state) meters may be tested instead in accordance with the plan outlined
in s.
PSC 113.0921.
(2) A stator balance test shall be performed on all new meters before being placed in service.
(3) Meters with electronic programmable registers may be shop tested on a periodic basis.
