Hardware Configuration Siemens Energy & Automation, Inc. 15 4 Har dwar e Configuration This chapter explains the device startup and how to config- ure the basic ISGS relay parameters. The r elay must be con- figured with certain system parameters, such as phase sequence and frequency .
Hardware Configuration 16 Siemens Energy & Automation, Inc. 4.2 Device Configuration The Device Configuration function allows you to set up the ISGS relay to matc h line frequency , pha se sequence, and breaker connection settings of your system. The frequency parameter (1002) must be set to the nominal frequency of your system.
Hardware Configuration Siemens Energy & Automation, Inc. 17 Figure 4.5 shows option board 2 and its jumpers. The draw- ing indicates the jumpers associated with each binary input. The enlarged set of pins shows an example of pin labeling and a jumper at location X17-X18.
Hardware Configuration 18 Siemens Energy & Automation, Inc. 4.4 CT Configuration The CT Configuration function allows you to set up the ISGS relay to match the phase CT primary rating, the neutral or ground CT primary rating, and the CT input s normal power flow setting of your system.
Hardware Configuration Siemens Energy & Automation, Inc. 19 V oltage transformers may be connected in either of two ways: T wo VT s con nected open delta-open delta Three VT s connected wye-wye For brevity , the open delta connection is referred to as L-L (line-to-line), while the wye connection is referred to as L-N (line-to-neutral).

Protective Function Configuration Siemens Energy & Automation, Inc. 21 5 Pr o tective Function Configuration 5.1 Overview This chapter explains how to set the parameters for the protective functions of the ISGS r elay . Password All parameter changes require a passwor d.
Protective Function Configuration 22 Siemens Energy & Automation, Inc. 5.3 High-Set Instantaneous Phase Overcurr ent (50HS) The High-Set Instantaneous Phase Overcurrent function causes an undelayed trip when any individual measured phase current exceeds the pr eprogrammed threshold (pickup value).
Protective Function Configuration Siemens Energy & Automation, Inc. 23 5.6 Phase Time Overcurrent (51) The Phase Time Overcurrent function uses a selected time overcurr ent characteri stic curve to determine the trip time for the applied phase currents.
Protective Function Configuration 24 Siemens Energy & Automation, Inc. protective curve that integrates with instantaneous reset. The lower limit of the custom curve is 1.
Protective Function Configuration Siemens Energy & Automation, Inc. 25 The Directional Phase Time Ov ercurr ent function can be enabled or disabled (1901). The Curve parameter (1902) allows the selection of the pre- programme d characteristic curve used by this function.
Protective Function Configuration 26 Siemens Energy & Automation, Inc. The range of the pickup value (2003) depends on the sec- ondary phase neutral CT rating (1 A or 5 A) and the value is in secondary amperes. The function begins timing when any individual neutral current exceeds the pickup current setting.
Protective Function Configuration Siemens Energy & Automation, Inc. 27 The Undervoltage function can be enabled or disabled (2301). The Curve parameter (2302) allows the selectio n of a definite time delay or a characteristic curve. When the definite time characteristic is selected, the time delay begins as soon as the device goes into pickup.
Protective Function Configuration 28 Siemens Energy & Automation, Inc. When the curve is set to inverse, the Max T ime parameter (2456) sets an absolute maximum amou nt of time that the function will remain in pickup regar dless of the inverse curve.
Protective Function Configuration Siemens Energy & Automation, Inc. 29 The 50BF Breaker Failure function can be enabled and dis- abled (2801). When enabled, the protective function begins monitoring the current flow in the circuit following a trip com- mand by the relay .
Protective Function Configuration 30 Siemens Energy & Automation, Inc. Demand calculations are made every subperiod (3103, 3104, or 3105). The number of subperiods depends on the length of the demand interval and is based on 10, the mini- mum number of monitoring intervals in a subperiod.
Control & Communications Siemens Energy & Automation, Inc. 31 6 Contr ol & Communications 6.1 Matrixing Events to Outputs One of the powerful functions of the ISGS relay is its ability to send control outputs based on inputs from the r eal world.
Control & Communications 32 Siemens Energy & Automation, Inc. Matrixing Procedur e The following steps provide a detailed description on how to matrix the ISGS relay manually using the front panel LCD and keypad. Before matrixing the re lay , ensure that power is applied to the relay which is indicated by the lit system LED (green).
Control & Communications Siemens Energy & Automation, Inc. 33 6.2 Binary Inputs Binary inputs are optically-isolated voltage level sensors with a fixed threshold. The input is considered activated if voltage above the threshold is applied and de -activated if no voltage or voltage below the threshold is applied.
Control & Communications 34 Siemens Energy & Automation, Inc. 6.4 T rip Contacts The ISGS relay of fers up to three trip contacts which are monitored by the micr oprocessor . T rip contacts may be con- figured by the user to trip the relay based on any of a number of functions.
Control & Communications Siemens Energy & Automation, Inc. 35 The T rip Source Impedance parameter (8301) can be enabled or disabled. When enabled, the circuit periodically monitors the trip s.
Control & Communications 36 Siemens Energy & Automation, Inc. 6.8 Breaker Operations Count Breaker Operations refers to the number of times the device has opened the breaker . The Breaker Operation function allows the setting of the breaker monitoring parameters.
Control & Communications Siemens Energy & Automation, Inc. 37 Binary Outputs (7409) displays the output contact status as illustrated in Figure 6.
Control & Communications 38 Siemens Energy & Automation, Inc. Figure 6.4 V oltage Balance Threshold Monitoring is done when the maximum voltage is larger than the voltage balance pickup value . The voltage is considered balanced and will not cause an alarm if the voltage min/max ratio is larger than the voltage balance factor .

Control & Communications 40 Siemens Energy & Automation, Inc. and, therefor e, apply to both sets. Examples ar e protective function enable settings and matrixed output contacts such as waveform buffers and blocking. All parameter set func- tions require a passwor d.
Control & Communications Siemens Energy & Automation, Inc. 41 6.12 Communications Port The Configure Communications Port function lets the user change the communications parameters for the ISGS relay . The ISGS relay can connect at 2400, 4800, 9600, and 19,200 baud at both ports (7201 and 7202).

Data Acquisition Siemens Energy & Automation, Inc. 43 7 Data Acquisition The ISGS relay pr ovides several forms of data acquisition and display to give the user the most comprehensive picture of the power system.
Data Acquisition 44 Siemens Energy & Automation, Inc. For each log the following applies: The ISGS relay keeps a lifetime count of protective func- tion trips. The trip number (address 001) is the count at the time of the trip. The trip number cannot be reset unless the relay is returned to the factory .
Data Acquisition Siemens Energy & Automation, Inc. 45 7.3.2 V oltage Minim um/Maximum Log The V oltage Minimum/Maximum Log function allows the dis- play of minimum and maximum values measured by the relay . The collected information is compared against previ- ously stored values and the log is updated.
Data Acquisition 46 Siemens Energy & Automation, Inc. 7.4 Metered Data Metered data is stored by the ISGS r elay and can be dis- played by accessing address blocks 4100 to 4900. The di s- play of this data does not requir e a password. Y ou can display the same data more conveniently by using W isdom software described in Chapter 8 .
Data Acquisition Siemens Energy & Automation, Inc. 47 7.5 Meter Display The Operating Parameters function allows the user to deter- mine what appears in Line 1 and Line 2 of the Power On Meter display described in Chapter 4 .
