S*0A Protection Relay Test Set
S*0A is a type of 3â€phase protection relay test set, with 3×*0A, 3×**0V, and a local
control system. It is a portable and economic secondary injection tester, and easy
to use. This 3â€phase protection relay testing set can apply to the testing not only
on operating value and operating time of AC/DC relays, but also on complex
voltage
blocking directional overâ€current, zero
sequence overâ€current, lowâ€frequency
load shedding and
other protection
functions of low voltage line
microâ€processor based protection
and whole group transmission of
high voltage line micro-processor based protection, and on starting value, quickâ€break value, harmonic blocking
value and manual synchronization of microâ€processor based transformer differential protection.
S*0A is
an ideal secondary injection tester
for all power utilities, power
plants, relay manufactures,
panel manufactures, research institutes, universities, testing companies, etc.
