Figure 1.1: SEL-387E Relay Functional Overview Current Differential Protection The SEL-387E Relay includes independent restrained and unrestrained current differential elements. The restrained element has a dual-slope, variable-percentage restraint characteristic. Use the fifth-harmonic element to prevent relay misoperation during allowable overexcitation conditions.
Page 9: Restricted Earth Fault Protection
Restricted Earth Fault Protection The SEL-387E Relay provides sensitive detection of internal ground faults via the Restricted Earth Fault (REF) protection element. The Winding 3 inputs are used for introduction of neutral CT polarizing current. Operating current is derived from the residual current calculated for the protected winding.
Page 10: Frequency Protection
Thermal stress from fault currents damages insulation. The SEL-387E Relay provides a through- fault event monitor to gather fault current level, duration, and date/time for each through fault.

Characteristic Operating The SEL-387E Relay has three differential elements (87R-1, 87R-2, and 87R-3). These elements employ Operate (IOP) and Restraint (IRT) quantities that the relay calculates from the winding input currents. Figure 3.1 shows the relay characteristic. You can set the characteristic as either a single-slope, percentage differential characteristic or as a dual-slope, variable-percentage differential characteristic.

The general equation for a line is: x • More specifically, in the SEL-387E Relay: • 1 Because the line starts at the origin, the value of c is normally zero. The sum of the second- and fourth-harmonic currents now forms the constant c in the equation, raising the relay characteristic proportionally to the harmonic values.

Page 55: Dc Ratio Blocking
The dc ratio blocking feature applies to inrush cases with little harmonic content, but a high dc offset. The measurement principle is that of wave shape recognition, distinguishing between the time constants for inrush current that typically are longer than the time constants for an internal fault.

Range: Y, N, Y1 The SEL-387E Relay has three sets of three-phase current inputs. Depending on the application, you may not need all of these inputs for the differential zone of protection. You can configure any unused terminals for stand-alone overcurrent protection. The E87Wn setting specifies which of the terminals the relay is to include in the differential calculation.
Page 57: Ct Ratio (Ctr1 Through Ctr3)
For delta-connected CTs, the secondary currents into the SEL-387E Relay current inputs are phase-phase difference currents (e.g., phase-phase difference current I – I flows into current input IAWn). To create a pseudo phase-neutral value for display or use in algorithms, these phase-phase difference currents are divided by √3 (divided by 1.732).

The SEL-387E Relay measures the amount of second-harmonic current flowing in the transformer. You can set the relay to block the percentage restrained differential element if the ratio of second-harmonic current to fundamental current (IF2/IF1) is greater than the PCT2 setting.

Application Description Overexcitation occurs when a transformer magnetic core becomes saturated. When this happens, stray flux is induced in nonlaminated components, causing overheating. In the SEL-387E Relay a volts/hertz element detects overexcitation. The SEL-387E Relay provides a sensitive definite- time volts/hertz element, plus a tripping element with a composite operating time. The relay calculates the present transformer volts/hertz as a percent of nominal, based on the present and nominal voltages and frequencies.

ATTERY ONITOR Use the station dc battery monitor in the SEL-387E Relay to alarm for undervoltage and overvoltage dc battery conditions and to view how station dc battery voltage fluctuates during tripping, closing, and other dc control functions. The monitor measures station dc battery voltage applied to the rear-panel terminals labeled Z25 (+) and Z26 (–).
Page 182: Detection Of Voltage Dips In Event Reports
REAKER ONITOR The SEL-387E Relay breaker monitoring function captures information on the number of operations and total interrupted current for as many as three breakers. These data are used to estimate the amount of contact wear per pole, based on wear curve information the user derives from breaker manufacturer maintenance curves and enters into the relay.
Page 183: Breaker Wear Curve Description And Settings
In order to capture trip information for other Breaker 1 trips initiated by devices other than the SEL-387E Relay, BKMON n must be set to sense these trips. This can be done, for example, by using an input to monitor the trip bus for the given breaker. This is illustrated in Figure 5.4, where IN106 is connected to the Breaker 1 trip bus and asserts for any trip from any source.
Page 184 The two straight line segments of the curve between the three defined points define the number of operations as a function of current in kiloamperes by an equation of the form: α I • 5-12 Metering and Monitoring Date Code 20080110 SEL-387E Instruction Manual...

Transfer" message to enable the SEL-387E Relay to transmit unsolicited binary SER messages. 2. When SER records are triggered in the SEL-387E, the relay responds with an unsolicited binary SER message. If this message has a valid checksum, it must be acknowledged by sending an acknowledge message with the same response number as contained in the original message.
Page 502: Functions And Function Codes
Upon power-up, the SEL-387E Relay disables its own unsolicited transmissions. This function enables the SEL-387E Relay to begin sending unsolicited data to the device which sent the enable message, if the SEL-387E has such data to transfer. The message format for function code 0x01 is shown below.
Page 503: 0X02-Function Code: Disable Unsolicited Data Transfer
The function 0x18 is used for the transmission of unsolicited Sequential Events Recorder (SER) data from the SEL-387E Relay. This function code is also passed as data in the “Enable Unsolicited Data Transfer” and the “Disable Unsolicited Data Transfer” messages to indicate which type of unsolicited data should be enabled or disabled.

Page 507: Appendix G: Distributed Network Protocol (Dnp3
(DNP3) VERVIEW Some versions of the SEL-387E family of relays support Distributed Network Protocol (DNP3) L2 Slave protocol. This includes access to metering data, protection elements (Relay Word), contact I/O, targets, Sequential Events Recorder, breaker monitor, relay summary event reports, settings groups, and time synchronization.
Page 508: Data-Link Operation
When the SEL-387E decides to transmit on the DNP link, it has to wait if the physical connection is in use. The SEL-387E monitors physical connections by using CTS input (treated as a Data Carrier Detect) and monitoring character receipt.
