The characteristic curve shape is selected to be the same type as the other relays on the same circuit or to grade with items of plant e.g. fuses or earthing resistors.

The relay will revert to its usual settings (51-n) after elapse of the cold load period. This is determined either by a user set delay, or by the current in all 3-phases falling below a set level (usually related to normal load levels) for a user set period. ©2010 Siemens Protection Devices Limited Chapter 7 Page 22 of 49...

A number of studies have been made to determine the optimum MTA settings e.g. W.K Sonnemann’s paper “A Study of Directional Element Connections for Phase Relays”.

Characteristic Angle will change if NPS Polarising is used.

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.

Their withstand is specified in two parts; continuous capability based on a figure of I , and short time capability based on a constant, K, where K = (I t.

DTL also prevents operation during transient disturbances. The use of IDMTL protection is not recommended because of the difficulty of choosing settings to ensure correct co-ordination and security of supply. ©2010 Siemens Protection Devices Limited Chapter 7 Page 31 of 49...

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. ©2010 Siemens Protection Devices Limited Chapter 7 Page 33 of 49...
