Signalling instead of switching – Residual current monitoring in earthed systems Pages  
In TN systems, the star point of the feeding transformers is connected to earth through a low impedance and the exposed conductive parts of the electrical installation are connected to the…  
IT systems as reflected in the standards Pages  
Figure 13: The second fault in the IT system In accordance with IEC 60364-4-41:2017-03, subclause 411.6.4, after an initial fault occurs, the conditions for an automatic disconnection following a…  
Insulation fault location in coupled systems Pages  
Plain text messages simplify the search New measuring methods also make it possible to locate high-impedance faults with high system leakage capacitances and low locating currents. The faulty…  
Applications in focus Pages  
Bender technology is used in a variety of applications. We guarantee electrical safety worldwide for example in the fields of mechanical engineering, healthcare, mining, power generation,…  
Variable-speed drives and pulsing ground-fault location Pages  
The effect of harmonics from VFD’s on ground-fault protection Variable-speed drives use semiconductor components to rectify and invert voltage and current. To create an AC output, the internal DC…  
Conversion of a solidly grounded system into an HRG system Pages  
Why NGR’s require continuous monitoring The neutral-grounding resistor (NGR) is a critical element of a high-resistance-grounded (HRG) electrical power system. HRG systems always include…  
Insulation resistance - testing, measuring, monitoring Pages  
During periodic tests the measurement of the insulation resistance is part of the measurements to be undertaken in accordance with DIN VDE 0105-100 (VDE 0105-100):2009-10. The insulation…  
Switching main distribution boards in hospitals reliably Pages  
Buildings engineering incorporates solutions for supply, monitoring and control of all modern buildings. These modern buildings include, among others, hospitals with systems which need to be…  
Displaying, signalling and operating in hospitals Pages  
Hospitals are centrally controlled and monitored. Data and alarms recorded locally should be forwarded to the central control room with no delay. Access to the Bender monitoring devices is simple…  
Continuous monitoring of de-energised loads and conductors Pages  
Your benefits Continuous monitoring instead of insulation measurement based on random samples during recurrent testing Avoiding expensive and unplanned system shutdowns Higher productivity …
