Application Notes

Conformal Coating

The new coating feature provides an additional level of protection for SIPROTEC devices used in extremely harsh environmental conditions.

Arc protection

The integrated arc fault protection functionality is employed for the fast clearance of arcing faults on busbars and within metal clad switchgear and associated cable boxes.

Phasor Measurement Unit (PMU)

Phasor Measurement Units (PMUs) are integrated in SIPROTEC 5 devices. Its measured synchrophasors make a valuable contribution to the dynamic monitoring of transient processes in energy supply systems.

Transient ground fault function

The high sampling rate of SIPROTEC 5 devices enables the cost effective integration of reliable and powerful high-impedance ground faults detection functions.

Process bus

SIPROTEC 5 process bus provides versatile solutions and migration concepts for new and existing systems. SIPROTEC 6MU85 Merging Unit is designed for conventional and non-conventional instrument transformers (LPITs).

Capacitor bank protection

Capacitor banks require the use of extensive protection functionality. SIPROTEC 5 protection devices integrate the standard protection functions and specific capacitor protection functions.
