GE manufactures a full line of highly accurate, dry type (oil-free) current and voltage transformers for indoor and outdoor metering and relay applications. These products provide customers a means for transforming high voltages and currents down to lower levels that standard meters and relays can measure. Superbute™, GE's robust butyl encapsulated epoxy designs for higher voltage and current classes, are known for their reliability. Accubute™ designs offer increased accuracy over a broader range of operation enabling customers to reduce their inventory of different ratios while upgrading the accuracy of their metering installations.
