sub.net-TCP is a portable instrument for testing both the circuit breaker mechanisms and the substation battery. It can be used during routine maintenance or on a continuous basis if a problem is suspected.
The system is housed in a small, rugged suitcase style enclosure which includes the power, signal and communications cables. A compact programmer is available for configuring sub.net – TCP and viewing the test reports.
sub.net-TCP is easy to use and only requires two input connections. Once connected a complete substation can be tested without having to reconnect to each circuit breaker. Sub.net-TCP will automatically record, analyse and report on each trip and close operation and will send these reports to a central location for viewing and archiving via a PSTN or wireless modem.
