    2.1 Product description The L60 Line Phase Comparison System is part of the Universal Relay (UR) series of products. It provides a simple phase- comparison principle successfully employed by analog and static relays for many years, along with the significant advantages of a modern microprocessor-based relay.
  • Page 16: Description

    Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when purchased as an option. Secure Routable GOOSE (R-GOOSE) is supported with software options. Settings and actual values can be accessed from the front panel or EnerVista software. The figures show typical two-terminal and three-terminal applications.

  • Page 17 PRODUCT DESCRIPTION Figure 2-1: 87PC communications The L60 uses flash memory technology that allows field upgrading as new features are added. Firmware and software are upgradable. The following single-line diagram illustrates the relay functionality using American National Standards Institute (ANSI) device numbers.

  • Page 19: Security

    The L60 supports password entry from a local or remote connection. Local access is defined as any access to settings or commands via the faceplate interface. This includes both keypad entry and the through the faceplate RS232 port. Remote access is defined as any access to settings or commands via any rear communications port.

  • Page 22: Order Codes

    Module options are specified at the time of ordering. The L60 is specified with either one CT/VT module (8P) or two CT/VT modules (8F and 8P). When the L60 is applied in two- breaker configurations (such as breaker-and-a-half or ring configurations), the currents from the two CTs are summed internally within the relay or externally.

  • Page 26: Replacement Modules

    Replacement modules can be ordered separately. When ordering a replacement CPU module or faceplate, provide the serial number of your existing unit. Not all replacement modules apply to the L60 relay. The modules specified in the order codes for the L60 are available as replacement modules for the L60.

    5.2.2.1 Background The L60 is ordered with two CT/VT modules. If two breakers are involved in an application, the current must be summed externally. With two CT/VT modules, the L60 allows the connection of two breaker CTs directly to the relay, processing the currents individually for some functions and summing them for other functions by employing the sources mechanism.
  • Page 174 Sources, in the context of L60 relays, refer to the logical grouping of current and voltage signals such that one source contains all the signals required to measure the load or fault in a particular power apparatus. A given source can contain all or some of the following signals: three-phase currents, single-phase ground current, three-phase voltages and an auxiliary voltages from a single-phase VT for checking for synchronism.
  • Page 175 Upon startup, the CPU configures the settings required to characterize the current and voltage inputs, and it displays them in the appropriate section in the sequence of the banks (as described earlier) as follows for a maximum configuration: F1, F5, L1, L5, S1, and S5.

    Selected records can be cleared from user-programmable conditions with FlexLogic operands.

  • Page 255 NUMBER: 0 The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the L60 over a network. The L60 operates as a TFTP server.

    Setup for IRIG-B is illustrated in the Installation chapter. For the Other protocols, whenever a time synchronization message is received through any of the active protocols, the L60 clock updates. However, given that IEC 60870-5-103, IEC 60870-5-104, Modbus, and DNP are low-accuracy time synchronization methods, avoid their use for synchronization when better accuracy time protocols, such as IRIG-B and PTP, are active in the system.

The L60 supports the Precision Time Protocol (PTP) specified in IEEE Std 1588 2008 using the Power Profile (PP) specified in IEEE Std C37.238 2011. This enables the relay to synchronize to the international time standard over an Ethernet network that implements PP.
  • Page 264 When a clock on start-up discovers that it is “better” than the present grandmaster, it assumes the grandmaster role and the previous grandmaster reverts to slave. The L60 qualification mechanism accepts a potential master clock as a new grandmaster, when in a four-second interval it has received three announce messages from it, all better than the present grandmaster clock and better than any other announce in this interval.

  • Page 567: Application Of Settings

    8.1 87PC phase comparison element 8.1.1 Overview The L60 provides 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 comparison, 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 568 The L60 allows you to check and set channel symmetry without using an oscilloscope, by means of FlexLogic operands and applying the corresponding current to the relays, which in turn key the PLC and consequently measure MARK and SPACE signals on the oscillography.
  • Page 569: Settings Example

    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.

    LV bus fault can result in a loss of sensitivity. If the tapped transformer is a source of zero sequence infeed, then the L60 zero-sequence current removal has to be enabled as described in the next section.
  • Page 572: Transformer Load Currents

    8.2.3 Transformer load currents The L60 can be applied on the line with a tapped transformer. Since the tapped line can be energized from one terminal only, or there can be a low current flowing through the line, the phase-comparison element must set to provide stability.
  • Page 573: Tractional Load

    8.2.6 Tractional load Where tractional load is tapped from the line protected by the L60, significant and variable negative-sequence current can exist on the line, thereby not allowing sensitive FDL and FDH settings. On such lines, it is beneficial to detect faults based on change in the sequence components of the currents.

  • Page 575: Single-pole Tripping Applications

    DISTANCE/BACKUP SUPERVISION 8.2.8 Single-pole tripping applications The L60 provides functionality for single-pole tripping from 87PC, distance functions, or instantaneous overcurrent elements via the trip output element. 87PC can detect internal faults on the line but not faulted phases, since the phase currents are combined in one quantity.
  • Page 576: Phase Distance

    The current supervision alone does not prevent maloperation in such circumstances. Keep in mind that the fuse failure element provided on the L60 needs some time to detect fuse fail conditions. This can create a race between the instantaneous zone 1 and the fuse failure element. Therefore, for maximum security, it is recommended to both set the current supervision above the maximum load current and use the fuse failure function.
  • Page 577: Ground Distance

    Ground directional overcurrent functions available in the relay can be used in conjunction with the Zone 2 distance element to key the scheme and initiate its operation. This provides increased coverage for high-resistance faults. L60 LINE PHASE COMPARISON SYSTEM – INSTRUCTION MANUAL 8-11...
  • Page 578: Series Compensated Lines

    This situation is encountered when it is desired to account for the zero sequence inter-circuit mutual coupling. This is not a problem for the ground distance elements in the L60 that do have a current reversal logic built into their design as part of the technique used to improve ground fault directionality.
  • Page 579 As the characteristics of sub-synchronous oscillations are in complex relations with fault and system parameters, no solid setting recommendations are given with respect to extra security margin for sub-synchronous oscillations. It is strongly recommended to use a power system simulator to verify the reach settings or to use an adaptive L60 feature for dynamic reach control.

    For short transmission lines, the charging current is a small factor and can therefore be treated as an unknown error.
