ÝÊ0604 measures
|
- effective value of mains voltage (U)
- network frequency (F)
- current effective value of the single-phase short circuit (SC) to "ground" and
"Z"
- phase-shift between voltage and current of the single-phase short-circuit (j),
and cosj
- disconnecting differential current of the protective disconnection device (ID n)
- disconnection time of the protective disconnection device (T)
- direct-current resistance (R)

Safety
parameter meter of electrical installation of buildings ÝÊ0604 is
a measuring means (GOST 22261) and it is designed to measure the
parameters of the power network grounded the neutral and the parameters
of the protective disconnection device (ÓÇÎ-Á) during acceptance (certification)
tests of the electrical installation of the house and industrial
buildings.
