Residual current monitoring to the final circuit

 
Special sensors and measurement technique for residual current monitoring to the final circuit. ✔ Small ✔ Flexible ✔ six-channel ✔ split core  

Pages

Continuous monitoring of de-energised loads and conductors

 
Many types of loads that are temporarily or mainly disconnected (standby mode) must function reliably when needed. This applies, for example, to fire pumps, slide-valve drives, lift motors or…  

Pages

Variable-speed drives and pulsing ground-fault location

 
In a low-voltage (typically 600 V or less) high-resistance-grounded (HRG) electrical power system, ground-fault current is limited to a low-enough level that the system need not be immediately…  

Pages

Conversion of a solidly grounded system into an HRG system

 
To avoid the situation in which a ground fault is not detectable, leaving the system in an unsafe condition, continuously monitor the NGR with an appropriate device. The NGR must be monitored for…

Pages

Electrical safety for high resistance grounded systems

 
Other installations rely on HRG to allow continued operation with one ground fault.  Refineries, saw mills, petrochemical facilities, factories, pipelines, food processors, and pulp mills are…  

Pages

Continuous availability, operational reliability and cost efficiency through permanent residual current monitoring

 
I∆ Residual current/Fault current I∆n Response residual current RF Fault resistance RL Load resistance IF insulation fault I1, I2 Operating current US Supply voltage PE …  

Pages

How does residual current monitoring work?

 
RCMs differ in terms of type, frequency and waveform of the currents that they are capable of detecting: RCM series: Type A residual current monitors in accordance with IEC 60755 for monitoring…  

Pages

Why residual current monitoring?

 
The range of application of residual current monitors and systems extends from data centres, banks, insurances and office buildings, hospitals, traffic engineering to energy supply and…

Signalling instead of switching – Residual current monitoring in earthed systems

 
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…

TN-S/TT system

 
By the use of residual current monitoring systems, a message is given to the user before the shutdown threshold of an RCD is reached. RCMs (Residual Current Monitors) monitor residual currents in…
