New England Wire Technologies Corporation
Double and Triple Insulated Winding Wires and the ground. NEWind (R) Specialty Winding Wire solves this problem by insulating the conductors with thin layers of insulation. Cable insulation layers are extruded in either two layers (Supplementary) or three layers (Reinforced). This design ensures that defects in any one layer will not reduce the insulating ability. The result is motors and transformers that can be manufactured without additional insulation, thus reducing their cost and size. Insulation Colors: Clear. White. Black. Red. Green...

Triad Magnetics
Looking for Current Sense Transformers Current sense transformers "transform " AC electrical currents from larger-current values into smaller currents that are better suited for instruments, protective relays, and control circuits. This is achieved by developing a current in the secondary winding that is proportional to that of the primary. The isolation aspect of the transformer keeps the high voltage of the primary system separate from the instrument, safety circuit, or control circuit on the other side, thereby protecting them...

Fuji Electric Corp. of America
New Oil Immersed Transformers exceptional reliability. Fuji Electric designs transformers to ensure the highest efficiency without sacrificing cost-effectiveness. Through carefully engineered core construction, we minimize no-load loss. Additionally, by utilizing transposed conductors, preventing magnetization of metal adjacent to the winding, and incorporating magnetic shielding in the tank 's inner wall, we have significantly reduced stray-load loss. As a result, Fuji Electric transformers deliver superior efficiency... (read more) -
Triad Magnetics
Why Transformer Insulation Ratings Matter How Does Temperature Influence the Lifespan of a Transformer?. All electrical devices produce heat as an operational byproduct. In transformers, normal operation causes an internal temperature increase or temperature rise. When the transformer is at its nameplate rating, the transformer temperature rise is the average temperature increase of the windings above the ambient temperature. This increase in temperature has the potential to shorten the transformer 's lifespan. As a result, proper... (read more)Browse Transformers Datasheets for Triad Magnetics -
Triad Magnetics
Designing Effective Current Sense Transformers Design Considerations for Current Sense Transformers. Current sense transformers are instrument transformers designed to detect (i.e., sense) electrical current and convert (i.e., transform) it into a more usable and safe form for the connected device(s). They perform this function by measuring the current flow in the primary winding and producing a proportional current in the secondary winding, enabling the reduction of high-voltage current in the primary winding to a lower value...
