Type VIY-60Indoor voltage transformer

Instrument transformers

Product features − 5 kV indoor − 60 kV BIL, 60 Hertz − Primary volts: 2400 - 4800 − UL Recognized Component, File No. E148620

ApplicationThe VIY-60 indoor voltage transformer is designed for service in metalclad switchgear and is used for relaying, metering, and control power applications.

Construction featuresThe primary and secondary coils are wound using special winding and shielding techniques for improved voltage stress distribution. The coils are designed to withstand continuous operation at 1.1 times the line-to-line voltage level and the line-to-ground voltage level for Y burden units. For some line-to-ground voltage units, a short-time withstand voltage of 1.9 is available upon request.

Each coil is insulated with mylar film to provide a high dielectric strength between layers. The coils and core are combined to create a complete winding structure that is assembled to a support frame. The entire assembly is vacuum cast in polyurethane for added insulation and protection.

Fuse classificationsThis unit is provided with three fuse classifications: mounted fuse with hardware, unfused with hardware, or unfused without hardware. Optional fuse kits are offered to convert some unfused styles to fused styles. Consult your ABB sales representative concerning overvoltage conditions for designs above the standard rated voltage factor of 1.1.

TerminalsCompression-type primary terminals accommodate #8 through #2 wire. Secondary brass terminal inserts are 3/8" deep with a .190-32 tapped hole. Secondary terminals are .190-32 compression screws. A compression type terminal that accommodates #14 through #4 wire is provided on fused units on the line end of each fuse.

BaseplateThe baseplate is constructed of corrosion-resistant aluminum and is secured to the encapsulated base support.

MountingThe VIY-60 can be mounted in upright, cantilever, or upside-down positions.

CurvesType curves are available upon request.

Test reportsIEEE test reports are stored electronically and can be e-mailed in various formats at the time of shipment.

StandardsThis unit meets all applicable IEEE and NEMA standards and is a UL Recognized Component.
