`series resistor (electric instruments) A resistor that forms an
`essential part of the voltage circuit of an instrument and gen-
`erally is used to adapt the instrument to operate on some des-
`ignated voltage or voltages. The series resistor may be inter-
`nal or external to the instrument. Note: Inductors, capacitors,
`or combinations thereof are also used for this purpose. See

`series street-lighting transformer (power and distribution
`transformers) A series transformer that receives energy from
`a current-regulating series circuit and that transforms the en-
`ergy to another winding at the same or different current from
`that in the primary. See also: specialty transformer.
`(PE/TR) C57.12.80-1978r, [57]
`series system The arrangement in a multielectrode electrolytic
`cell whereby in each cell an anode connected to the positive
`bus bar is placed at one end and a cathode connected to the
`negative bus bar is placed at the other end, with the interven-
`ing unconnected electrodes acting as bipolar electrodes. See
`also: electrorefining.
`(EEC/PE) [119]
`series tee junction See: E-plane tee junction.
`series thyristor converter A thyristor converter in which two
`or more simple converters are connected in such a way that
`their direct voltages add and their commutations coincide.
`(IA/IPC) 444-1973w
`series transformer (1) (power and distribution transformers)
`A transformer with a “series” winding and an “exciting”
`winding, in which the “series” winding is placed in a series
`relationship in a circuit to change voltage or phase, or both,
`in that circuit as a result of input received from the “exciting”
`winding. Note: Applications of series transformers include:
`
`1) Use in a transformer such as a load-tap-changing or reg-
`ulating transformer to change the voltage or current duty
`of the load-tap-changing mechanism.
`2) Inclusion in a circuit for power factor correction to indi-
`rectly insert series capacitance in a circuit by connecting
`capacitors to the exciting winding.
`
`(PE/TR) C57.12.80-1978r
`(2) A transformer in which the primary winding is connected
`in series with a power-supply circuit, and that transfers energy
`to another circuit at the same or different current from that in
`the primary circuit. See also: transformer.
`(PE/TR) [57]
`series transformer rating (power and distribution trans-
`formers) The lumen rating of the series lamp, or the wattage
`rating of the multiple lamps, that the transformer is designed
`to operate.
`(PE/TR) C57.12.80-1978r
`series-trip recloser A recloser in which main-circuit current
`above a specified value, flowing through a solenoid or oper-
`ating coil, provides the energy necessary to open the main
`contacts.
`(SWG/PE) C37.100-1992
`series two-terminal pair networks Two-terminal pair networks
`are connected in series at the input or at the output terminals
`when their respective input or output terminals are in series.
`See also: network analysis.
`(BT) 153-1950w
`
`series undercurrent tripping See: direct release; undercurrent
`release.
`series unit (power and distribution transformers) The core
`and coil unit which has one winding connected in series in
`the line circuit.
`(PE/TR) C57.12.80-1978r
`series weighting Response weighting by separating a finger into
`individual elements with capacitive coupling between them;
`the elements may be separated from the bus bar.
`(UFFC) 1037-1992w
`series winding (1) (A) (autotransformer) (power and distri-
`bution transformers) That portion of the autotransformer
`winding which is not common to both the primary and the
`secondary circuits, but is connected in series between the in-
`put and output circuits. (B) (power and distribution trans-
`formers) The winding of the series unit which is connected
`in series in the line circuit. Note: If the main unit of a two-
`core transformer is an autotransformer, both units will have
`a series winding. In such cases, one is referred to as the series
`winding of the autotransformer and the other, the series wind-
`ing of the series unit.
`(PE/TR) C57.12.80-1978
`(2) That portion of the autotransformer winding that is not
`common to both the primary and secondary circuits, but is
`connected in series between the input and output circuits.
`(PE/TR) C57.15-1999
`series-wound (rotating machinery) A qualifying term applied
`to a machine to denote that the excitation is supplied by a
`winding or windings connected in series with or carrying a
`current proportional to that in the armature winding. See also:
`asynchronous machine.

`livering energy from the electricity supply system to the wir-
`ing system of the premises served.

`are connected in series. Speed is inversely proportional to the
`square root of load torque. Motor operates at a much higher
`speed at light load than at full load.

`message-based and register-based servants.

`cated to providing specific facilities to other devices attached
`to the network. Contrast: client. See also: mail server; disk

`server; print server.

`vices for use by clients on the same or another device.
