Siemens innovates with new sensor bushing, protection and indication devices
- April 12, 2023
Siemens Smart Infrastructure has expanded its industry-leading medium voltage portfolio with a sustainable and intelligent solution that paves the way for the smart switchgear of the future.
Due to its conformity with the instrument transformer standard IEC61869, the SIBushing can be connected to the SICAM FCM plus (Feeder Condition Monitor), a multi-functional, short-circuit and earth-fault indicator which uses detection algorithms to indicate the direction of the cable fault.
Applicable for medium voltage distribution systems up to 36kV, the SICAM FCM plus with SIBushing delivers unrivaled transparency and high-precision measurement of distribution systems, resulting also in the consumption of significantly less power, compared to conventional instrument transformer technologies.
Designed for compact, intelligent secondary substations, the SICAM FCM Plus provides system operators with a solution for fast fault location and more transparency in the distribution grid. It is suitable for grounded, isolated, and compensated networks. Moreover, SICAM FCM plus offers reduced cost of installation and minimal maintenance, while its adaptive integrated temperature compensation algorithm enables high-precision measurement without calibration and adjustment to the primary operating voltages and currents.

Protection Device
Also being unveiled at the event is the SIPROTEC 7SY82, a multifunctional protection device with LPIT inputs. This universal protection device joins the renowned SIPROTEC 5 product family of field devices for protection, control, monitoring, and measuring applications in electrical energy systems.
LPITs in combination with the universal SIPROTEC 7SY82 minimize device variance. As a result, customers optimize their investment and operating costs, gain time in project planning, and achieve significant savings in terms of logistics and spare parts. Additionally, LPIT technology enables customers to increase their sustainability and reduce the ecological footprint of their medium-voltage switchgear. Due to the new measuring inputs which conform with the instrument transformer standard IEC61869, it is possible to connect sensors that consume less power, is safer for operating personnel, and use fewer materials such as iron, copper, and cast resin, compared to conventional instrument transformers.
