6.3.1 Voltage Sag and Current Fault
Duration
Registers ( VSAG
Duration
, ISAG
Duration
)
Address: 6 (Voltage Sag Duration); 10 (Current Fault Duration)
Default = 0x000000
Voltage Sag Duration (VSAG
Duration
) and Current Fault
Duration
(ISAG
Duration
)
defines the number of instanta-
neous measurements utilized to determine a sag event. Setting these register to zero will disable this feature.
The value is represented in unsigned notation. See Section 5.6
6.3.2 Voltage Sag and Current Fault Level Registers ( VSAG
Level
, ISAG
Level
)
Address: 7 (
Voltage Sag Level
); 11 (
Current Fault Level
)
Default = 0x000000
Voltage Sag Level (VSAG
Level
) and Current Fault Level (ISAG
Level
) defines the voltage level that the magnitude
of input samples, averaged over the sag duration, must fall below in order to register a sag/fault condition. These
value are represented in unsigned notation and in the range of 0
VSAG
Level
1.0, with the binary point to the
right of the third MSB. See Section 5.6
