Please specify in the case of S Series.In the case of 3-phase, 4-wire,
please specify the phase
voltage and line voltage.
Although manufacturing will be performed even when specified in kvar units,
the specifications will be converted to var units on the rating nameplate.

Inherent reactive power value calculation example
* The primary-side reactive power (kvar) mentioned here is not the full-load reactive power based on the VT-CT rating. It refers to the reactive power value kvar
(primary-side reactive power value equivalent to the rated output value) to be controlled according to the power factor.
A reactive power transducer can be manufactured if the transducer inherent reactive power
is within the range of the table on the left.
In the case of bidirectional input, calculate using the larger of the lag or lead reactive powers.
In the case of a 3-phase, 3-wire, VT 6600/110V, CT 200/5A arrangement with the primary-side reactive power being 1200kvar:

*5.
Note 1.
In the case of unidirectional input, the lag side (LAG) is the reactive power unless particularly specified.
A CT must be inserted and used in the current circuit because reactive power transducers are three-current systems.
Operation will be abnormal when the input of the three-phase circuit is a negative-phase sequence.
For low-voltage circuits, grounding of the secondary sides of the instrument voltage transformer and current transformer is unnecessary.
