Page 11: Introduction Overview
The 339 Motor Protection System is a microprocessor based relay providing suitable protection of medium voltage motors. The small footprint and the withdrawable option make the 339 relay ideal for panel mounting on either new or retrofit installations. The combination of proven hardware, a variety of protection and control features, and communications, makes the relay ideal for total motor protection and control.
Page 12: Description Of The 339 Motor Protection System
Bus VT phase A voltage. The signals are passed through a low pass filter to prevent false zero crossings. Sampling is synchronized to the Va-x voltage zero crossing which results in better co-ordination for multiple 339 relays on the same bus. Phasors, Transients, and Harmonics Current waveforms are processed four times every cycle with a DC Offset Filter and a Discrete Fourier Transform (DFT).

If the motor starting times are well within the safe stall times, it is recommended that the 339 standard overload curve be used. The standard overload curves are a series of 15 curves, each a multiple from 1 to 15 of a common curve shape based on typical motor thermal limit curves.

Page 326: Breaker Health
CHAPTER 7: MAINTENANCE Breaker health The 339 relay provides breaker health information by monitoring and analyzing the tripping time, closing time and the spring charging time. The breaker health status depends on many factors, such as number of permissible operations, magnitude of breaking current, mechanical wear, and contact wear.

Page 335: Force Output Relays
M7 TESTING Force output relays The 339 relay provides a test to verify that the output relays function correctly. Any relay forced to operate will toggle from its normal state when there are no trips, alarms, or blocks, to its active state.
Page 336: General Maintenance
General maintenance The 339 requires minimal maintenance. As a microprocessor-based relay, its characteristics do not change over time. The expected service life of a 339 is 20 years when the environment and electrical conditions are within stated specifications. While the 339 performs continual self-tests, it is recommended that maintenance be scheduled with other system maintenance.
