• Primary terminals that are unfused are 1/4-20 brass screws with one flatwasher

and lockwasher.

• Primary terminals that are fused are 1/4-20 brass screws with one flatwasher

and lockwasher and two nuts.

• Secondary terminals are No. 10-32 brass screws with one flatwasher and

lockwasher.

• The core and coil assembly is vacuum encapsulated in polyurethane resin.

• Thermal burden rating is for 120 volt secondaries.

• Switch gear style is similar to fused style. No fuse or fuse clip is provide, but

inserts for fuse clips are supplied.

• A test card is provided with each unit.

(a) Two fuse transformers should not be used for Y connections. It is preferred practice to connect one lead from each voltage transformer directly to the neutral terminal, using a fuse

in the line side of the primary only. By using this connection a transformer can never be made “live” from the line side by reason of a blown fuse in the neutral side. For

continuous operation the transformer primary voltage should not exceed 110% of rated value.

(b) Voltage transformers connected line-to-ground cannot be considered to be grounding transformers and must not be operated with the secondaries in closed delta because

excessive currents may flow in the delta.

Note: It is recommended that system line-to-line voltage not exceed the transformer maximum system voltage level.

The circle diagram can be used to predict the performance of a transformer

for various loads and power factors. A convenient scale of volt-ampere is

shown on the unity power factor line (u.p.f) and commences at the zero or

no-load locus. To use the diagram, measure the known V.A. and scribe an arc

about the “Zero” locus of a length that contains the angle of the burden

power factor. The point at which the arc terminates is the error locus in phase

angle minutes and ratio correction factor.
