The calculation of the value of the Stability Resistor is based on the worst case where one CT fully saturates and the other balancing CT does not saturate at all. A separate Siemens Protection Devices Limited Publication is available covering the calculation procedure for REF protection. To summarise this: - The relay Stability (operating) Vs voltage is calculated using worst case lead burden to avoid relay operation for through-fault conditions where one of the CTs may be fully saturated.

Page 621: Neutral Overvoltage (59N)
NVD Application Typically NVD protection measures the residual voltage (3V ) directly from an open delta VT or from capacitor cones – see fig. 2.13-2 below. Figure 2.14-2 NVD Protection Connections © 2013 Siemens Protection Devices Limited Page 27 of 48...

Remedial action can then be taken, such as introducing a Balancer network of capacitors and inductors. Very high levels of NPS Voltage indicate incorrect phase sequence due to an incorrect connection. Page 28 of 48 ©2018 Siemens Protection Devices Limited...

Page 625: Section 3: Ct Requirements
Where the REF function is used then this dictates that the other protection functions are also used with class PX CTs. A full explanation of how to specify CTs for use with REF protection, and set REF relays is available on our website: www.siemens.com/energy © 2013 Siemens Protection Devices Limited Page 31 of 48...

For this reason each relay in an ARC scheme must be set with identical Instantaneous and Delayed sequence of trips. Figure 4.1-1 Sequence Co-ordination Page 32 of 48 ©2018 Siemens Protection Devices Limited...

Operation is subject to a time delay to prevent operation for transitory effects. A 3-phase CT failure is considered so unlikely (these being independent units) that this condition is not tested for. Page 38 of 48 ©2018 Siemens Protection Devices Limited...

For this reason, the relay allows these protection elements - under-voltage, directional over-current, etc. - to be inhibited if a VT failure occurs. © 2013 Siemens Protection Devices Limited Page 39 of 48...

Page 636 An increase in transformer or decrease in system frequency may result in the transformer becoming over-excited. The 81HBL5 element can be used to prevent protection operation e.g. prevent differential protection operation during acceptable over-excitation conditions.

Page 637 Load Blinders measure the system impedance and are set to differentiate between a fault having a relatively low impedance and a fault having a relatively high impedance. Additional measurands are also considered to increase the security of operation. Figure 5.9-1 Paralleled Transformers and Feeders © 2013 Siemens Protection Devices Limited Page 43 of 48...
