Electrical power supply panel with increased safety through monitoring and control

A method for monitoring, metering and improving system parameters, including residual current sensitivity setpoint and response over a time period in an electrical panel for a system having at least a single power incoming phase line X wherein a reaction and accuracy are critical to a decision to disconnect the power line with a malfunction prior to RCD (residual current device) operation at a standard setpoint for cutoff, said method comprising:

• a. setting a leakage current threshold in mA (milliAmp) that can be changed in setup mode;
• b. setting allowable deviation in leakage current from said setpoint in mA for alert;
• c. setting maximum deviation in mA to disconnect currents;
• d. setting N time period to include in an average calculation for a natural leakage current;
• e. measuring the difference in current between a main incoming phase and neutral lines;
• saving said difference in a data base as a natural leakage current value for line X with a time tag;
• g. calculating the average value of the line X leakage current in the last N time period;
• h. calculating the deviation of the current difference between the phase and the neutral for each load line at the present time, and the average value calculated for the last N time period for each load line;
• i. measuring the current in the ground conductor and comparing it to said measured difference;
• and
• j. calculating the difference between the current measured in the phase line and the neutral line and resetting maximum deviation in mA to disconnect current,
• such that upon exceeding the maximum deviation, the current to the panel is disconnected.
