Cast-Resin Voltage Transformers — Indoor & Outdoor

Voltage transformers for metering and protection, with separate indoor and outdoor constructions. Select the insulation level, voltage ratio, secondary arrangement, accuracy class and burden to match the installation.

Indoor reference: BPS-14I

The indoor BPS-14I is rated up to 17.5 kV under IEC 61869-3 and NBR 6855/21, or 15.5 kV under IEEE C57.13. Published data specify 60 Hz operation, up to two secondary windings and a thermal burden of 1,000 VA for one secondary or 2 × 500 VA for two. Approximate dimensions are 242 × 255 × 180 mm; stated weight is 18 kg.

Outdoor reference: BPS-14E

The outdoor BPS-14E has maximum voltage ratings of 17.5 kV under IEC, 15 kV under NBR and 15.5 kV under IEEE. Its datasheet specifies 60 Hz, one secondary and a 600 VA thermal burden. Approximate dimensions are 476 × 310 × 255 mm, with a stated weight of 18 kg.

Accuracy and insulation ratings depend on the applicable standard and selected configuration. Provide the installation environment, primary and secondary voltage, metering or protection duty, accuracy, burden and connection requirements when requesting a quotation.
