You can use the product to detect sparkovers at partial capacitances in the bushings and to monitor aging in the bushings. Change of capacitance ΔC1 To evaluate the condition of the bushing, the bushings are equipped with mea- surement equipment which constantly calculates the change of capacitance ΔC1 during operation. ΔC1 is calculated by the change in voltage between two phases of the system and provides conclusions about sparkovers at partial ca- pacitances in the bushings. The method is called a 2/3 reference algorithm be- low. For more information, see section Configuring capacitance monitoring [►Section 8.4.1.2, Page 155]. 20 Product description 8459847/06 EN Using the 2/3 reference algorithm implemented, the monitoring system can largely compensate for voltage and temperature fluctuations in the 3-phase sys- tem and thus ensure reliable monitoring of the bushings. Figure 4: Operating principle The bushing monitoring with 2/3 reference algorithm is also designed to moni- tor the bushings in systems in which a measurement of the reference grid volt- age is not possible. To do so, the system uses a constant reference grid voltage. The angle between phases is a constant 120°. Because the reference system voltage is not measured, strong asymme- i tries in the grid can lead to incorrect triggering of events. 4.4 Function description of MSENSE® BM-T The product is a monitoring system and is used to monitor capacitance graded bushings on power transformers. You can use the product to detect sparkovers at partial capacitances in the bushings and to monitor aging in the bushings. Change of capacitance ΔC1 To evaluate the condition of the bushing, the bushings are equipped with mea- surement equipment which constantly calculates the change of capacitance ΔC1 during operation. ΔC1 is calculated by the change in voltage between two phases of the system and provides conclusions about sparkovers at partial ca- pacitances in the bushings. The method is called a 2/3 reference algorithm be- low. For more information, see section Configuring capacitance monitoring [►Section 8.4.1.2, Page 155]. Constant comparison to a reference voltage increases the accuracy and elimi- nates the influence of asymmetries in the grid. Change of dissipation factor Δtanδ The system can determine the change of the dissipation factor Δtanδ of the bushings and thus monitor the aging of the bushing. For more information, see section Configuring dissipation factor monitoring [►Section 8.4.1.3, Page 158]. 8459847/06 EN Product description 21 Using the reference measurement and the 2/3 reference algorithm imple- mented, the monitoring system can largely compensate for voltage and tem- perature fluctuations in the 3-phase system and thus ensure reliable monitoring of the bushings. Figure 5: Operating principle (with the option "Reference measuring") The bushing monitoring variant with 2/3 reference algorithm combined with the reference voltage measurement Uref is used to monitor the bushings in sys- tems in which strong asymmetries in the grid could lead to incorrect triggering of events. To compensate for this, the system carries out a reference voltage measurement Uref. 4.5 Performance features bushing monitoring The MSENSE® BM monitoring system monitors the bushings of a power trans- former and has the following features: – Monitoring oil-impregnated paper bushings (OIP) and resin-impregnated pa- per bushings (RIP) of voltage levels Um = 66...420 kV (other voltage ranges available on request) – Optional: Monitoring of 6 bushings, where 3 bushings each form one set (field 1 and field 2) – Online monitoring of the bushing via capacitance measurement – Monitoring the change in capacitance C1 – Compensation for temperature fluctuations – Compensation for the effects of weather – Compensation for voltage fluctuations Only with option BM-T – Compensation for grid asymmetry (only with active reference system mea- suring) Only with option BM-T – Online monitoring of the bushing using dissipation-factor measurement (ref- erence voltage measurement) – 3-phase reference system (e.g. voltage transformer) with monitoring of the change in dissipation factor tanδ – Display of the measured and calculated values – Status messages via digital outputs – Web-based visualization – SCADA – IEC 60870-5-101 – IEC 60870-5-103 – IEC 60870-5-104 – IEC 61850 (edition 1 and edition 2) – Modbus (RTU, TCP, ASCII) – DNP3 22 Product description 8459847/06 EN 4.6 Operating modes Local mode (LOCAL) In the Local operating mode, you can make entries and input commands using the device's operating controls.
