350 Feeder Protection System
Chapter 1: Introduction
GE
Grid Solutions
Introduction
Overview
The 350 is a microprocessor-based relay for primary and backup over-current protection
of medium and low voltage distribution feeders. The relay is also suitable for providing
over-current and backup protection for small and medium size motors, transformers,
generators, and distribution bus-bars. The small footprint and the withdrawable option
make the 350 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 feeder protection and control. Equipped
with serial (RS485), USB, and Ethernet ports with the possibility of adding redundancy
(IEC62439, PRP and HSR), and a wide selection of protocols such as Modbus, DNP3.0, IEC
60870-5-103, 60870-5-104, IEC61850 GOOSE, OPC-UA, the 350 relay is the best-in-class
for MCCs and PCCs, SCADA and inter-relay communications. The 350 relay provides
excellent transparency with respect to power system conditions and events, through its
four-line 20-character display, as well as the EnerVista 3 Series Setup program.
Conveniently located LEDs provide indication of relay operation, alarm, and pickup, as well
as breaker, and relay status.
The 350 relay provides the following key benefits:
• Withdrawable small footprint – saves on rewiring and space. (non-draw out version is
also available)
• Multiple protection groups with the added flexibility of switching through a wide
selection of overcurrent protection and control features.
• Fast setup (Quick Setup) menu for power-system setup and a simple overcurrent
protection configuration.
• 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.

DESCRIPTION OF THE 350 FEEDER PROTECTION SYSTEM CHAPTER 1: INTRODUCTION
Description of the 350 Feeder 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 and 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 3 Series 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 350 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). The resulting phasors have fault current transients and all
harmonics removed. This results in an overcurrent relay 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
Protection elements are processed up to four times 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.
NOTE
NOTE: Arc Flash protection elements are processed up to 8 times every cycle.

CHAPTER 1: INTRODUCTION 350 ORDER CODES
350 FEEDER PROTECTION SYSTEM – QUICKSTART GUIDE 7
NOTE
NOTE: Features related to each order number are subject to change without notice.
Arc Flash System
The 350 protection relay with Input/Output option “A” supports up to 4 Arc Flash sensors,
which are ordered separately so that the connected sensor fiber lengths can be
customized.
FAST PATH: The total sensor fiber length connected to each loop sensor must not exceed 70 meters of
single sensor fiber. Black sensor fiber is duplex, and must be doubled in calculations.
For example, a loop sensor with a 25 meter transparent sensor fiber plus a sensor fiber
extension of 10 meters would have a total of 2 x 10m + 25m = 45m of single sensor fiber.
FAST PATH: The total sensor fiber length connected to each point sensor must not exceed 35 meters of
black (duplex) cable.
NOTE
NOTE: Generally each loop sensor is used with a sensor fiber extension, in order to minimize
exposure to ambient light when running the sensor fiber between cabinets. A duplex
sensor fiber extension connects the relay to the loop sensor, and can be gently pulled
apart to connect to the loop sensor connectors if they are not adjacent. Consider your
installation needs carefully when ordering sensor and extension lengths.
Empty chassis
The 350 protection relay chassis used with a drawout relay is available separately, for use
as a partial replacement or in test environments. Many features are supported by the
cards and ports within the chassis, as is reflected in the chassis order code.
NOTE
NOTE: The chassis order code and drawout relay order code must match exactly.
FAST PATH: A drawout relay cannot be used in a chassis with different order code options.

Figure 1-5:
The graph shows the trip time error with respect to the ratio of cable load and thermal
model pickup setting. With a smaller I/Ipkp ratio, the time error tends to be higher, as
accumulated through the logarithmic formula, the measurement error, and the time of
measurement. For higher I/Ipkp ratios, the time to trip is substantially more accurate. Each
point on the graph represents a trip time error, with the I/Ipkp ratio kept constant during
the test.
