Remarks
(1) The varmeters are bidirectional deflection indicators. Unidirectional deflection indicators can be manufactured upon request.
(2) In regards to “Indicator rating (Po) kvar” in the “Rating” column:
(3) Regarding the maximum scale of a varmeter
• With a bidirectional deflection indicator, the left side is LEAD and the right side is LAG with respect to “zero” as the central division, and the standard scale
indicates up to 1/2 of the maximum scale value. A scale indicating up to the maximum scale value can also be manufactured.
• With a unidirectional deflection indicator (with “zero” at the left end), the scale indicates up to the maximum scale value. Please specify LEAD or LAG; the
standard is LAG.
(4) Models with a 1A current rating; can also be manufactured; the power consumption is basically the same as that of a 5A model.
(5) The T-150 rectifier is a dedicated accessory (non-compatible accessory), and thus cannot be used in combinations other than those designated for the
indicators. The distance between the indicator and the T-150 rectifier must be 5m or less, or the round-trip lead wire resistance must be 0.5Ω or less.
(6) Use a varmeter with an input voltage in the range of 85 to 115% of the rated value (rated voltage ±15%).
The indication may be unstable when used with an input voltage of 85% or less of the rating or the input voltage is switched on and off.
(7) The weight of the T-150 rectifier is approximately 1kg.
(8) Please make sure to read the “Safety Precautions” (pp.5-8) and the “Selection Precautions” (p.9) to assist in selecting the model and use specifications
suited to the application.

Calculation example: In the case of a 3-phase, 3-wire circuit, VT 6600/110V and CT 100/5A, and a bidirectional deflection indicator
with a scale indicating up to 1/2 the maximum scale value.
Indicator scale P (kvar)= ✕✕Po (0.8~1.2)✕1/2 = 480~720kvar
The manufacturable range of the varmeter scale is thus LEAD (480 to 720) ~ 0 ~ LAG (480 to 720) kvar.
The manufacturable range differs slightly according to the rating. For details, refer to the “Varmeter Scale Selection Reference
Table” (p.60).
