● Ethernet (Modbus TCP) and
● TD500 test device.
Maintenance management example
Information for preventive maintenance, e.g. number of switching cycles or operating hours,
enables timely planning of personnel and material. Plant availability increases as a result
and irreparable damage to sensitive plant components caused by failures can be avoided.
Communication provides fast access to specific information about the location and cause of
power failures.
One example of tripping information:
Trip caused by 2317 A short circuit in phase L2 on August 27, 2013 at 14:27 p.m.
The specific details contained in this message are the basis for fast correction of the fault
and create a significant potential for cost savings.
Statistics and cost-effectiveness
Recording of electrical power, energy and the power factor opens up further possibilities.
Energy profiles for power distribution structures can be created and the costs can be clearly
allocated thanks to the transparent representation of energy consumption for business
administration analysis. Energy costs can later be optimized by compensating for load peaks
and troughs.
