5.2.1. Connection setup.
5.2.1.1. Type of electrical connections setup.
To set the type of connection, enter the CONNECTIONS SETUP Menu, place the cursor on GRID TYPE and
select one of the following options:
3PH+N-BL
3PH-BL
3PH
3PH+N = unbalanced three-phase system with neutral
2PH
1PH
5.2.1.2. Type of voltage and voltage ratio setup for the main channel.
PowerCompact3020 can measure both alternate and direct currents. The user must set the type of voltage to
be analysed, selecting among AC (alternate) y DC (direct).
Besides, When a voltmeter transformer has to be connected, i.e. when voltages higher than 600VAC must
be measured, the corresponding transformation ratio must be set (default value 230:230), changing the
values as needed.
5.2.1.3. Type of voltage and voltage ratio setup for auxiliar channel.
As described in the previous section, the same settings can be applied to the auxiliary voltage channel U
Aux.
5.2.1.4. Cogeneration setup.
PowerCompact3020 can also be configured to measure the power and energy that might be generated. To
do so, place the cursor on GENERATION and select ON.
By selecting OFF, the instrument will stop measuring the power generated, which will be
.
NOTE: when changing fron Generation ON to Generation OFF,
Connections setup menu allows the user to set the following
parameters:
type of electrical network to which the instrument is connected.
type of voltage and voltage ratio for phases L1, L2, and L3.
type of voltage and voltage ratio for U AUX
activate/deactivate measurements in cogeneration mode.
automatically adjust the zero level of measuring channels.
check if the instrument and relevant probes are connected to the
electrical system correctly.
= balanced three-phase system with neutral
= balanced three-phase system without neutral
= unbalanced three-phase system without neutral
= two-phase system
= single-phase system
