Measurement Parameters

The setup ENVT (External Neutral Voltage Tap) presence command (command code = 46472) configures the content of the system type register.

Address	Register	RW	X	Unit	Type	Range	Description
0x0CF1	3314	R-WC	–	–	INT16U	30, 31, 40, 41	System type Factory setting: 40 with ETV trip system

Determining system type:

If...	Then...	Result
the system type is a three-pole circuit breaker with external neutral current transformer and without external neutral voltage tap	system type = 30	Measurements of the phase-to-phase voltages are available. Measurements of the phase-to-neutral voltages are not available Measurements of the neutral current is available. 3 wattmeters method is not possible.
the system type is a three-pole circuit breaker without external neutral current transformer and without external neutral voltage tap	system type = 31	Measurements of the phase-to-phase voltages are available. Measurements of the phase-to-neutral voltages are not available Measurements of the neutral current is not available . 3 wattmeters method is not possible.
the system type is a three-pole circuit breaker without external neutral current transformer and with external neutral voltage tap	system type = 40	Measurements of the phase-to-phase voltages are available. Measurements of the phase-to-neutral voltages are available Measurements of the neutral current is not available. 3 wattmeters method is possible.
the system type is a three-pole circuit breaker with external neutral current transformer and external neutral voltage tap, or if the system type is four-pole circuit breaker	system type = 41	Measurements of the phase-to-phase voltages are available. Measurements of the phase-to-neutral voltages are available Measurements of the neutral current is available. 3 wattmeters method is possible.

1 = the active power flows from downstream (bottom) to upstream (top).

The current demand configuration command (command code = 47243) configures the content of registers 3351 and 3352.

The power demand configuration command (command code = 47244) configures the content of registers 3354 and 3355.

Address	Register	RW	X	Unit	Type	Range	Description
0x0D17	3352	R-WC	x1	min	INT16U	5–60	Duration of the current demand calculation window, adjustable in steps of 1 minute. The factory setting is 15 minutes ⁽¹⁾
0x0D1A	3355	R-WC	x1	min	INT16U	5–60	Duration of the power demand calculation window, adjustable in steps of 1 minute. The factory setting is 15 minutes.
(1) The duration in minutes of the current demand calculation window set in this register is used for the maximum current I1, I2, and I3, and IN protection functions. When these protection functions are active, it is possible to modify the duration of the calculation window whether the protective cover for the dial settings is closed or not, whether remote access is authorized (ETV trip system) or not, and whether the supervisor knows the remote access control word or not.

The setup nominal primary voltage Vn display command (command code = 47245) configures the content of the nominal voltage register.
