The SMV Max Delay setting defines how long the receiver waits for the SMV frames
before activating the ALARM output. This setting can be accessed via Configuration/
System. Waiting for the SMV frames also delays the local measurements of the
receiver to keep them correctly time aligned. The SMV Max Delay values include
sampling, processing and network delay.
Frequency adaptive measurements for residual current can be activated with the
setting Frequency adaptivity. Two selections are provided.

RESTCTR setting Frequency adaptivity is visible only if system
setting Configuration/System/Frequency adaptivity is set to
"Enable".

Monitored data

Monitored data is available in three locations.
• Monitoring/I/O status/Analog inputs
• Monitoring/IED status/SMV traffic
• Monitoring/IED status/SMV accuracy
Description
Frequency adaptive measurements are disabled
for this UTVTR. Measurements are fixed to
nominal frequency defined with Configuration/
System/Rated frequency.
Frequency adaptive measurements are enabled.
In this case, the estimated network frequency is
defined by another preprocessing block.
