145-302

Overview

The GE Model 145-302 is an indoor current transformer designed for use with electric meters and measuring devices. It features a solid core construction and operates within a frequency range of 50 to 400 Hz at 600 volts with a 10kV BIL rating. The unit has a 3000:5 turns ratio and a C800 accuracy class. Physical dimensions include a window diameter of 6.00 inches, height of 11.91 inches, depth of 3.00 inches, and width of 11.10 inches, weighing 83.0 lbs.

Feature Summary

Solid core construction for reliable current sensing
Designed for indoor installation environments
Supports frequency ranges from 50 to 400 Hz

Applications

Connection with electric meters
Integration with measuring devices
Instrument transformer testing circuits

Procurement Notes

Verify the specific manufacturer origin, as the model number appears associated with both General Electric and other instrument transformer divisions. Confirm physical mounting requirements due to the significant weight of 83.0 lbs and large window diameter. Ensure the application voltage does not exceed the 600V rating and that the indoor environment meets the insulation requirements for a 10kV BIL rating.

Selection Notes

Select this component when a high-ratio (3000:5) current transformation is required for metering applications. The C800 accuracy class indicates suitability for precise measurement tasks. Consider the physical footprint and weight constraints during installation planning. Verify compatibility with the connected device's input impedance and the system's operating frequency between 50 and 400 Hz.

Part Context

This model belongs to the series of instrument transformers used in electrical distribution systems for billing and monitoring purposes. These devices step down high primary currents to standardized secondary levels for safe handling by instrumentation. The 145 series typically denotes a specific form factor or mounting style within the manufacturer's historical product line for indoor switchgear or panel applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When replacing, ensure the new unit matches the 3000:5 ratio, C800 accuracy class, and physical dimensions to maintain fit and function.
