11. Protection releases - General notes Emax, the range of ABB air circuit-breakers, now has a new range of electronic relays. These are called PR121, PR122 and PR123, and they substitute the previous range PR111, PR112 and PR113. The new protection releases integrate all the functions of their predecessors, adding new and interesting technical features that are useful for satisfying every current and future system installation need.
If in doubt, about its safe usage, the unit must be put out of service to prevent any accidental use. You must assume that safe usage is impossible if: 1. the unit shows visible signs of damage. 2. the unit does not function (for example with autotest or with the trip test unit). 3. the unit has been damaged in transit. WARNING: Prior to servicing and/or replacing, the circuit-breaker must be open. Also remember to disconnect all power supplies connected. 11.1.1.

Test bus on front test connector. 13.2.6. Protection functions The PR122/P protection unit carries out 8 independent protection functions. In particular: 1. Protection against overload with inverse time “L”; 2. Protection against short-circuit with adjustable delay “S”; 3.
13.2.8. Watchdog The PR122/P unit provides some watchdog functions able to guarantee the proper management of relay malfunctions. These functions are as follows: Watchdog for presence of Auxiliary power supply with “plug” icon displayed. RATING PLUG validity. Watchdog for proper connection of the current sensors (CS). If it is enabled, any anomalies are indicated by a special alarm message and the “alarm” LED coming on, and the circuit-breaker opens after 1s.
The function can be disabled and it is a setting characteristic of the single protection units. The start-up function enables the protection threshold (S, I and G) to be changed during a time interval lasting “ts”, starting from “start-up”. The latter must be intended as follows: - Passage of at least one of the phase currents above the activation threshold of the adjustable Start-Up with SD TestBus2, Ekip Connect or PR010/T (0.1…10In, by 0.
to guarantee correct operation of the relay on the supply side. 13.2.9.3.1 Start-up threshold “I” The start-up function can be selected. The function can be enabled from the menu on the protection “I” page. The function behaves in exactly the same way as the protection “S” (see par. 13.2.9.9.2). 13.2.9.4. Protection “MCR” against closing on short-circuit The MCR function is used to protect the system against closing.
% Unb = I max − I min . 100 where Imax is the maximum and Imin is the minimum phase current. I max WARNING: It is possible to disable the trip control of the protection (“Enable Trip: Off”). In that case, for the whole duration of the unbalance the CB will not be opened, but only the condition will be signaled by means of the “warning” LED lit up and a warning message.
This protection is available on 4-pole or 3-pole CBs with neutral voltage available (see circuit diagram 48). On 3-pole CBs, presence of neutral voltage must be set by the “neutral voltage present” parameter. 13.2.9.9.4 Protection “U” The disable-type, fixed-time protection trips when - for a time higher than or equal to t6 time set - an unbalance between two or more line voltages greater than I6, is detected.

For greater peak factors,consult ABB 14.2.2.1. Self-powering Self-powering enables the protection unit to be powered with the busbar current using current transformers. Using this supply mode, only the unit’s protection functions are assured, however, not the accessory functions regarding the modules.

Protection against phase unbalance “U”; Protection against overtemperature “OT”; Protection against undervoltage “UV”; Protection against overvoltage “OV”; Protection against residual voltage “RV”; Protection against reverse active power “RP”; Underfrequency “UF”; Overfrequency “OF”. The PR123/P unit allows current signal processing of the neutral pole with different relationships relative to the value of the phases. N.B.: Beyond 15.
14.2.8. Watchdog The PR123/P unit provides some watchdog functions able to guarantee the proper management of relay malfunctions. These functions are as follows: Watchdog for presence of Auxiliary power supply with “plug” icon displayed. RATING PLUG validity. Watchdog for proper connection of the current sensors (CS). If it is enabled, any anomalies are indicated by a special alarm message and the “alarm” LED coming on, and the circuit-breaker opens after 1s.
14.2.9.2.2 Start-up threshold “S” The start-up function can be selected in the case where the curve with fixed time is selected. The start-up function can be selected in the case where the curve with fixed time is selected. The function can be disabled and it is a setting characteristic of the single protection units. The start-up function enables the protection threshold (S, D, I and G) to be changed during a time interval lasting “ts”, starting from “start-up”.
14.2.9.3. Double S Thanks to the new PR123/P release that enables two independent and simultaneously active protection S thresholds to be specified, selectivity can assured even in critical conditions. This function enables a better selectivity level to be obtained than using a release without a “double S”. This function is valid for t=K only. 14.2.9.4.
The general behavior is summarized in the table below. (Example with power flow setting “Top Bottom”). Ifault (If) Value If < I7 If > I7 If > I7 If > I7 If > I7 Outputs status Direction either Top Bottom Top Bottom Bottom Top Bottom Top DFout 0 1 1 0 0 Inputs status DBout 0 0 0 1 1 DFin either 0 1 either either T trip DBin either either either 1 0 No trip ts t7FW t7BW ts If the power flow is in phase with the direction set on the relay, the output DFout is enabled (1).
14.2.9.5.1 Start-up threshold “I” The start-up function can be selected. The function can be enabled from the menu on the protection “I” page. The function behaves in exactly the same way as the protection “S” (see par. 14.2.9.2.2). 14.2.9.6. Protection against closing on short-circuit “MCR” The MCR function is used to protect the system against closing. If activated (the protection can be enabled/disabled), it operates only in the presence of Vaux or PR120/V, and with Protection “I” disabled.
14.2.9.9. Protection against overtemperature inside the relay “OT” There is a sensor inside the PR123/P unit that monitors the temperature of the unit. This enables the signalling of any abnormal temperature conditions, which could cause temporary or continuous malfunctions of the unit’s electronic components. This protection has two states of operation: State of “WARNING TEMPERATURE” with –25°C < temp. < -20°C or 70°C < temp. < 85°C : the display is turned off and the “WARNING” LED flashes at 0.
14.2.9.12. Protection against reverse active power “RP” The PR123/P unit provides protection (which can be disabled) with an adjustable fixed time (t = k), against reverse active power, active both with self-powering and auxiliary supply. When the total reverse active power (sum of the power of the 3 phases) exceeds the set reverse active power threshold P11 the protection counts down the preset time interval t11 and then opens.

16.3. Data Logger (recorder) The data logger function is available on the PR122/P and PR123/P units and it can be used to save the instantaneous values of certain analog and digital measurements automatically in a large-sized memory buffer. The data can easily be downloaded from the unit using either the SD-TestBus application via a Modbus bus, and transferred to any personal computer for processing. The function stops the recording every time a trip occurs in order to facilitate failure analysis. 16.3.1.
16.3.2.4. Setting and viewing customized stop events (triggers) From the system, you can set customized stop events (triggers) to coincide with the events shown in paragraph 16.4. In the event of a customized trigger point, the following window is displayed: 5/5 Stop event L Prealarm Any Trip Custom None 16.3.2.5. Setting the stopping delay The stopping delay can be set between 0.00 [s] and 10.00 [s], in 0.01 [s] steps. 4/6 Data logger Sampling freq. Stop delay Enter Stop event 0.
Maximum recording time is established by the sampling frequency set only, as described in the table in paragraph 16.4.2.2; recording time may be lower than maximum time attainable when the sum of stopping delay and time elapsing between a restart trigger and a trigger is lower than the maximum value, as described in the figure below: Recording time Stopping delay Restart Trigger Trigger Maximum recording time 16.3.4. Description of the information given by the Data Logger system 16.3.4.1.
16.3.4.3. Information from the system on the configuration and status of the Data Logger The following information is provided on the status of the data logger: STATUS Waiting trigger: Data Logger triggered: Data Logger stopped: this means that the data logger is enabled and waiting for the occurrence of the event selected as the trigger. this indicates that the trigger event has occurred and the data logger is still recording.
16.4.3.

Two toroidal sizes are available: the small toroid can be installed on E1 and E2 three-pole sizes, the medium toroid can be installed on E1 and E2 four-pole sizes and on E3 three-pole sizes. The PR122/P LSIRc unit provides all PR122/P LSI functions but with one addition: protection against residual current faults.
