4.5.4.3. CONNECTION FOR NETWORK PEAK VALUE MONITORING /
MEASUREMENTS
External electrical current converters including load resistances are necessary for
network peak-value monitoring and current measurement. Such must be designed so
that a measurement voltage of 1V~ unfolds as operating at a nominal electrical current
(voltage at the load resistance). These converters must be assembled into the network
supply of the facility for the purpose of network peak-value monitoring. The converter
17 18
type (for electrical current or for voltage), as well as their nominal values, should be
configured using a PC program!

measurement
An external electrical current converter (input 1) and an external voltage converter (input 2)
are needed for (single-phase) power and energy measurement. Input 3 may further be
deployed, additionally. Again, both converters must be configured in a manner so that a
1V~ measurement voltage is generated at a nominal electrical current and at a nominal
voltage. For this reason, the electrical current converter must be equipped with an
adequate load resistance, and possibly, an adequate series resistance must deploy
together with the voltage converter. The internal resistance of the measurement device is
7540 Ohms.
