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 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. Equipped
with serial (RS485), USB, and Ethernet ports, and a wide selection of protocols such as
Modbus, DNP3.0, IEC 60870-5-103, 60870-5-104, GOOSE, the relay is the best-in-class for
MCCs, SCADA and inter-relay communications. The relay provides excellent transparency
with respect to power system conditions and events, through its four-line 20-character
display, as well as the EnerVista SR3 Setup program. Conveniently located LEDs provide
indication of overall relay operation, as well as alarm, pickup, and motor status.
The relay provides the following key benefits:
• Withdrawable small footprint – saves on rewiring and space.
• Fast setup (Quick Setup) menu provided, to guide users through a wide range of motor
management applications.
• Large four-line LCD display, LEDs, and an easy-to-navigate keypad.
• Multiple communication protocols for simultaneous access when integrated into
monitoring and control systems.

339 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 1–3
Description of the 339 Motor Protection System
CPU
Relay functions are controlled by two processors: a Freescale MPC5554 32-bit
microprocessor measures all analog signals and digital inputs and controls all output
relays; a Freescale MPC520B 32-bit microprocessor controls all the Ethernet
communication protocols.
Analog Input Waveform Capture
Magnetic transformers are used to scale-down the incoming analog signals from the
source instrument transformers. The analog signals are then passed through a 960 Hz low
pass anti-aliasing filter. All signals are then simultaneously captured by sample and hold
buffers to ensure there are no phase shifts. The signals are converted to digital values by a
12-bit A/D converter before finally being passed on to the CPU for analysis.
Both current and voltage are sampled thirty-two times per power frequency cycle. These
‘raw’ samples are scaled in software, then placed into the waveform capture buffer, thus
emulating a fault recorder. The waveforms can be retrieved from the relay via the EnerVista
SR3 Setup software for display and diagnostics.
Frequency
Frequency measurement is accomplished by measuring the time between zero crossings
of the 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 relays on the same bus.
Phasors, Transients, and Harmonics
Current waveforms are processed twice every cycle with a DC Offset Filter and a Discrete
Fourier Transform (DFT). The resulting phasors have fault current transients and all
harmonics removed. This results in a motor that is extremely secure and reliable; one that
will not overreach.
Processing of AC Current Inputs
The DC Offset Filter is an infinite impulse response (IIR) digital filter, which removes the DC
component from the asymmetrical current present at the moment a fault occurs. This is
done for all current signals used for overcurrent protection; voltage signals bypass the DC
Offset Filter. This filter ensures no overreach of the overcurrent protection.
The Discrete Fourier Transform (DFT) uses exactly one sample cycle to calculate a phasor
quantity which represents the signal at the fundamental frequency; all harmonic
components are removed. All subsequent calculations (e.g. RMS, power, etc.) are based
upon the current and voltage phasors, such that the resulting values have no harmonic
components.
Protection Elements
All protection elements are processed twice every cycle to determine if a pickup has
occurred or a timer has expired. The protection elements use RMS current/voltage, based
on the magnitude of the phasor. Hence, protection is impervious to both harmonics and DC
transients.
