    1.5.5 BATTERY TAB The battery tab is installed in the power supply module before the L60 shipped from the factory. The battery tab prolongs battery life in the event the relay is powered down for long periods of time before installation. The battery is responsible for backing up event records, oscillography, data logger, and real-time clock information when the relay is powered off.

    The L60 supports 2 and 3-terminal applications, can be used for single- and three-pole tripping applications, and sup- ports breaker-and-a-half applications. Multiple backup functions include three-zone phase and ground distance, directional overcurrent, pilot schemes, and current and voltage elements.
  • Page 26 Another option provides two 10BaseF fiber optic ports for redundancy. The Ethernet port supports IEC 61850, Modbus TCP, and TFTP protocols, and allows access to the relay via any standard web browser (L60 web pages). The IEC 60870- 5-104 protocol is supported on the Ethernet port. DNP 3.0 and IEC 60870-5-104 cannot be enabled at the same time.

    (see Chapter 3 for full details of relay modules). The L60 can be ordered either with one Type 8P CT/VT module or with two CT/VT modules (8P plus 8F). The L60 is ordered with one CT/VT module for applications where one set of three-phase line currents is supplied to the relay. Voltage based functions are not available on units with one CT/VT module.

    (Rear View) * Optional This diagram is based on the following order code: L60-E00-HCL-F8P-H6G-L6D-N6K-S6C-U6H-W7Z. The purpose of this diagram is to provide an example of how the relay is typically wired, not specifically how to wire your own relay. Please CAUTION refer to the following pages for examples to help you wire your relay correctly based on your own relay configuration and order code.

    (see the Self-Test Errors table in Chapter 7) or control power is lost, the relay will de-energize. For high reliability systems, the L60 has a redundant option in which two L60 power supplies are placed in parallel on the bus.
  • Page 50: Ct/vt Modules

    CT connections for both ABC and ACB phase rotations are identical as shown in the Typical Wiring Diagram. The exact placement of a zero-sequence CT so that ground fault current will be detected is shown below. Twisted pair cabling on the zero-sequence CT is recommended. L60 Line Phase Comparison Relay GE Multilin...
  • Page 51 Synchrocheck and Volts/Hertz features. The L60 uses a special CT/VT module not available on other UR-series relays. This Type 8P module has four current inputs and special communications inputs/outputs for interfacing with PLCs. The communications interface requires an external DC source (station battery) to drive inputs/outputs as shown in the L60 Channel Communications section in this chapter.
  • Page 52: Contact Inputs/outputs

    The terminal configuration for contact inputs is different for the two applications. The digital inputs are grouped with a common return. The L60 has two versions of grouping: four inputs per common return and two inputs per common return. When a digital input/output module is ordered, four inputs per common is used. The four inputs per common allows for high-density inputs in combination with outputs, with a compromise of four inputs sharing one common.

  • Page 101: Display Properties

    Some customers prefer very low currents to display as zero, while others prefer the current be displayed even when the value reflects noise rather than the actual signal. The L60 applies a cut- off value to the magnitudes and angles of the measured currents.
  • Page 102 The L60 applies a cut-off value to the magnitudes and angles of the measured voltages. If the magnitude is below the cut-off level, it is substituted with zero.
  • Page 103: Clear Relay Records

    Selected records can be cleared from user-programmable conditions with FlexLogic™ operands. Assigning user-program- mable pushbuttons to clear specific records are typical applications for these commands. Since the L60 responds to rising edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.

    8.2 SINGLE-POLE TRIPPING 8.2.2 PHASE SELECTION The L60 uses phase relations between current symmetrical components for phase selection. First, the algorithm validates if there is enough zero-, positive-, and negative-sequence currents for reliable analysis. The comparison is adaptive; that is, the magnitudes of the three symmetrical components used mutually as restraints confirm if a given component is large enough to be used for phase selection.

    9 APPLICATION OF SETTINGS 9.1PHASE COMPARISON ELEMENT 87PC 9.1.1 DESCRIPTION The L60 Phase Comparison relay is designed to provide high-speed protection of transmission lines against all phase and ground faults when operated in the “mixed-excitation” mode. The term “mixed-excitation”, when applied to phase compari- son, describes a scheme that first mixes different sequence quantities in a given proportion and phase angle, then performs a phase-comparison based on this mix.
  • Page 370 Different methods can be used. The L60 allows the customer to check and set phase delay without using an oscilloscope and by means of FlexLogic™ operands and applying the corresponding current to both relays. Oscillography shows the time difference (including PLC delay and line propagation time) between local and remote signals.

  • Page 373: Lines With Tapped Transformers

    9.2.3 TRANSFORMER LOAD CURRENTS The L60 can be applied on the line with a tapped transformer. Since the tapped line may be energized from one terminal only, or there may be a low current flowing through the line, the phase-comparison element must set to provide stability.
  • Page 374: Tractional Load

    9.2 DISTANCE BACKUP/SUPERVISION 9 APPLICATION OF SETTINGS The L60 measures total harmonic distortion (THD) in all three phase currents and neutral current. These measurements are available for protection purposes though FlexElements™ (universal comparators). The FlexElement™ output can be used to block sensitive neutral instantaneous overcurrent or phase comparison on transformer energization.

    9.2.8 SINGLE-POLE TRIPPING APPLICATIONS The L60 provides functionality for single-pole tripping from 87PC, distance functions, or instantaneous overcurrent ele- ments via the Trip Output element. 87PC can detect internal faults on the line but not faulted phases, since the phase cur- rents are combined in one quantity.

    This situation is encountered when it is desired to account for the zero sequence inter-circuit mutual cou- pling. This is not a problem for the ground distance elements in the L60 which do have a current reversal logic built into their design as part of the technique used to improve ground fault directionality.

    The L60 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks. The TP4/CLNP profile requires the L60 to have a network address or Network Service Access Point (NSAP) to establish a communication link. The TCP/IP profile requires the L60 to have an IP address to establish communications. These addresses are located in the menu.
