JVW-4 -5, two-bushing model
Notes:
For continuous operation, the transformer-rated primary voltage should not be
exceeded by more than 10%. Under emergency conditions, over-voltage must be
limited to 1.25 times the transformer primary-voltage rating for two-bushing models,
and 1.40 times the rating for single-bushing models.
Applies to transformers connected Y-Y on a circuit in which the line-to-line voltage
is the same as the transformer-rated primary voltage. In each case, the transformer
is operated with reduced voltage and reduced excitation (58% of normal). In
determining the accuracy classification under such conditions, the Volt-Ampere
rating of the burden is maintained constant, regardless of the transformer
secondary voltage.
The prime symbol () is used to signify that these burdens do not correspond to
standard ANSI definitions.
Single-bushing design with removable grounding strap.

Note:
1. Voltage transformers of this type are available for use in 50 Hz appli-
cations in many ratings. However, Industry Standard IEEE 57.13 to which
we test transformers does not apply at 50 Hz. Customers who order
voltage transformers for 50 Hz application should provide an accuracy
specification including Burden VA and Power Factor. If an accuracy
specification is not made available, the transformer(s) will be tested at
60 Hz with test burdens as defined in IEEE 57.13 for 60 Hz application.
