A disadvantage of the classical P core design has always been the narrow wire slots, making it diffi cult to make strong coil formers with integrated solder pins. In the PTS design this problem is solved by cutting away the sides of both core halves. This creates ample room for wires and coil former fl anges. A range of special PTS coil formers is available but also most standard P core accessories can be used.

GE TRANSFORMER PROTECTION RELAY The T60 Transformer Protection System is part of the Universal Relay (UR) series of products. It is a microprocessor-based relay for protection of small, medium, and large three-phase power transformers. The relay can be configured for a maximum of six three-phase current inputs and six ground current inputs, and can satisfy applications with transformer windings connected between two breakers, such as in a ring bus or in breaker-and-a-half configurations. The T60 performs magnitude and phase shift compensation internally, eliminating requirements for external CT connections and auxiliary CTs.
These Current Transformers are manufactured in Wound Primary type and Window type construction. It is manufactured using Automatic Pressure Gelation casting and Vacuum Casting Technique. It ranges from 3.3 kV to 33 kV.
