Date Code 20170601 Instruction Manual SEL-387-0, -5, -6 Relay
SEL-387 Relay Command Summary
All commands that begin TFE apply to the SEL-387-5 and SEL-387-6 Relays
TFE Displays cumulative and individual through-fault event data. The twenty (20) most recent individual events are
displayed.
TFE n Displays cumulative and individual through-fault event data. The n most recent individual events are displayed,
where n = 1 to 1200.
TFE A Displays cumulative and individual through-fault event data. All the most recent individual events
are displayed, up to 1200.
TFE C Clears/resets cumulative and individual through-fault event data.
TFE P Preloads cumulative through-fault event data.
TFE R Clears/resets cumulative and individual through-fault event data.
All commands that begin THE apply to the SEL-387-6 Relay
THE Displays a thermal monitor report that indicates the present thermal status of the transformer.
THE n Displays saved thermal monitor report n where n = 1 is the most recently saved report.
THE C Clears the hourly profile, daily profile, and thermal event data archives.
THE D x y Retrieves daily profile data from day x to day y.
If x and y are omitted, retrieves entire profile data.
If x or y is omitted, retrieves profile from day x (y) to present.
THE H x y Retrieves hourly profile data from day x to day y.
If x and y are omitted, retrieves entire profile data.
If x or y is omitted, retries profile from day x (y) to present.
THE P n Loads preset value of accumulated insulation loss of life.
THE R Clears the hourly profile, daily profile, and thermal event data archives and resets the total loss-of-life values.
THE T Displays the four temperature inputs received from an SEL-2032, an SEL-2030, or
an SEL-2020 Communications Processor.
TIM Show or set time (24 hour time). Show time presently in the relay by entering just TIM. Example time 22:47:36
is entered with command TIM 22:47:36.
TRI Trigger an event report.
Access Level 2
Commands
The Access Level 2 commands primarily allow the user to change settings or operate relay
parameters and output contacts. All Access Level 1 commands can also be executed from Access
Level 2. The screen prompt is: =>>
ACC Enter Access Level 1. If the main board password jumper (JMP6A) is not in place, the relay prompts for the
entry of the Access Level 1 password in order to enter Access Level 1.
BAC Enter Access Level B. If the main board password jumper (JMP6A) is not in place, the relay prompts for the
entry of the Access Level B password in order to enter Access Level B.
BRE Breaker report shows trip counters, trip currents, and wear data for up to four breakers.
BRE R n Reset trip counters, trip currents, and wear data for breaker n (n = 1, 2, 3, 4, A).
BRE W n Preset the percent contact wear for each pole of breaker n (n = 1, 2, 3, or 4).
CAL Moves from Access Level 2 to Access Level C.
CEV n Show compressed winding event report number n, at 1/4-cycle resolution.
Attach DIF for compressed differential element report, at 1/4-cycle resolution.
Attach R for compressed raw winding data report, at 1/16-cycle resolution.
Attach Sm for 1/m-cycle resolution (m = 4 or 8 for filtered data; m = 4, 8, 16, 32, or 64 for raw data).
CLO n Assert the CCn Relay Word bit. Used to close breaker n if CCn is assigned to an output contact. JMP6B has to be
in place to enable this command.
Access Level B
Commands
The Access Level B commands allow the user to control breakers and contact outputs. All Access
Level 1 commands can also be executed from Access Level B. The screen prompt is: ==>
