TPC-1 it is first handheld teleprotection command tester. It allow to make fast test of command send threw digital or analog teleprotection equipment like: SWT3000, NSD580, PowerLink, ETL6x0, FOX615. During manufacturing we can set voltages as you need ex. 220/48V, 125/48V, 220/125V or any other in 40-250V range.

What you can do with TPC-1:

- Generate 220V or 48V impulse 1-2000ms,

- Measure response time 0.1ms resolution,

- Measure return impulse duration,

- Lunch 220V or 48V pulse generator,

- Count sent and received impulses,

- Run loopback with specified delay 0-5000ms

VS-1 is simply to use remote voltage source that allow to make loopback on remote side for command tests.

Benefits of VS-1:

- Comfortable handheld device,

- Up to 12h constant command (SWT3000 IFC-D 220V),

- Short resist,

- Separated from substation battery,
