Functional Overview
The SEL-2664 Field Ground Module calculates field
winding insulation resistance in the rotor of a synchronous generator. The measurement can be obtained from
an energized or de-energized generator. Insulation resistance values are transmitted to an SEL-300G, SEL-700G,
or SEL-2664S relay for the field ground protection element (64F) alarm and/or trip functions.
The SEL-300G, SEL-700G, and SEL-2664S relays use
the field insulation resistance value to detect a ground
fault in an ungrounded field winding of a generator. By
detecting a ground fault in the field winding, users are
alerted to a possible short-circuited field winding. Avoid
significant damage to the generator by taking corrective
actions before a second ground path occurs.
NOTE: The rotor iron of the generator must be grounded to
guarantee accurate measurement of the insulation resistance between field winding and ground. Follow the
machine manufacturer’s guidelines for grounding practices of the rotor iron.
The SEL-2664 transmits the field insulation resistance
value as far as 1000 meters using inexpensive fiber-optic
cable. The SEL-2664 works with continuous field voltages as high as 750 Vdc, and is able to withstand
1500 Vdc for one minute.

An SEL-300G, SEL-700G, or SEL-2664S Protective
Relay Application
The SEL-300G, SEL-700G, and SEL-2664S Protective
Relays have a selectable field ground protection element
(64F) that uses the SEL-2664 Field Ground Module to
acquire insulation resistance data for alarm and trip functions. Connect the SEL-2664 to the SEL-300G as shown
in Figure 2. On the SEL-700G and SEL-2664S relays, the
fiber-optic PORT 2 connects directly to the SEL-2664.
Use a fiber-optic cable and an SEL-2812M Transceiver to
transmit the insulation resistance data to the SEL-300G.
The EIA-232 port used must be set for an SEL protocol
and a data rate of 9600 bps, 8 data bits, no parity, and
1 stop bit to start receiving the insulation resistance value
from the SEL-2664. Set and test the SEL-300G as
directed in the SEL-300G Multifunction Generator Relay
Instruction Manual. Refer to the SEL-700G Instruction
Manual for similar settings and application details.

Figure 2 Field Ground Protection Using an SEL-300G Relay and an SEL-2664 Field Ground Module (An SEL-700G
application is similar)
The SEL-2664S Stator Ground Protection Relay supports
a similar application. When the SEL-2664 calculates the
insulation resistance value between the field winding and
ground, it uses a fiber-optic cable with ST connectors to
transmit the insulation resistance value to the fiber-optic
port (PORT 2) of the SEL-2664S. Consult the SEL-2664S
Instruction Manual for detailed instructions on setting up
the SEL-2664. You need to set the fiber-optic serial port
(PORT 2) in the SEL-2664S to SEL protocol and 9600
bps, 8 data bits, no parity, and 1 stop bit to start receiving
the insulation resistance value from the SEL-2664.
SEL-300G and SEL-700G Requirements for an
SEL-2664 Application
If the field ground protection functionality is to be added
to an existing SEL-300G installation, use the following
checklist to determine the requirements. All SEL-700G
models, except the SEL-700GT model, support the field
ground protection using the SEL-2664.
Existing SEL-300G
Recommended Actions for an SEL-2664 Application
Firmware version R1xx
Contact the factory for a replacement SEL-300G.
Firmware version R2xx
Consult with the factory about a hardware upgrade or a replacement SEL-300G.
Firmware version R3xx
Order a firmware conversion kit from the factory to field upgrade firmware to R323 or later.
EIA-232 Serial Port 2 or
Port 3 availability
EIA-232 Port 2 or Port 3 availability is required to connect the SEL-2664 using a fiber-optic cable and
an SEL-2812M Transceiver. Visit the SEL website or call the factory for cable selection and ordering
information.

SEL-2664 Data Packet Definition
The SEL-2664 sends a binary data packet approximately
every half period of the square-wave injection voltage.
When the injection frequency is selected at 0.25 Hz, the
packet transmits every 2 seconds. When the injection frequency is selected at 1.0 Hz, the packet transmits every
500 milliseconds. The packet contains data for insulation
resistance and self-test status; therefore no software setting is necessary in the SEL-2664. The SEL-2812M
Fiber-Optic Transceiver (with ST connectors) plus any
EIA-232 device can be configured to process the binary
packet contents shown in Table 4.

The SEL-2664 front faceplate TX LED is pulsed when it is
transmitting data.
SEL-2664 Self Test
The SEL-2664 runs a variety of self tests. When there is a
failure and the device is disabled, the module will extinguish the ENABLED LED. Table 5.1 in the SEL-2664 Field
Ground Module Instruction Manual lists hardware selftests, test methods, and actions taken.
SEL-2664 Injection Voltage Frequency
Selection Criteria
The SEL-2664 injects a square-wave voltage at a fixed
injection frequency (Fg) to the generator field winding.
The fixed frequency Fg can be selected between two
values, 0.25 Hz or 1 Hz, using a jumper located on the
main board of the SEL-2664. If jumper 1A is at the OPEN
position, the frequency of the square-wave voltage
injection is 0.25 Hz. If jumper 1A is at the CLOSE position, the frequency of the square-wave voltage injection is
1 Hz.
For generators with an overall field-to-ground capacitance
(Cfg) less than 2.5 microfarads, Fg can be set to 1 Hz and
ensure the stated accuracy for the 64F element. For generators with Cfg less than 10 microfarads, Fg should be set
at 0.25 Hz to ensure the stated accuracy for the 64F element. The SEL-2664 works with other generators that
have overall field-to-ground capacitance more than
10 microfarads, but the actual error may not be within the
stated accuracy.
When Fg is set at 1 Hz, the SEL-2664 measures insulation
resistance every 0.5 seconds. If operating time is important to your applications, follow the guidelines in Table 5
to select the frequency for the square-wave dc signal
injection. Otherwise, leave the module at its default
jumper setting of 0.25 Hz.
