Digital individual ground alarm SZI with 4 operating levels. It is fine to use for the cable circuits dielectric resistance and signaling, centralization and blocking equipment monitoring.
the equipment has 4 operating levels: 1operating level (14+1,4) кОm voltage pattern by DC current from 5 to 17 V; 2 operating level (28+2,8) кОm voltage pattern by DC current from 17 to 31 V; 3 operating level (60+6,0) кОm voltage pattern by DC current from 31 to 71 V; 4 operating level (220+22) кОm voltage pattern by DC current from 71 to 245 V, voltage pattern by AC current 220V.
power supply 220+22 V, 50 Hz
consumption current (AC current) – max 10 mA
entrance friction 1,0 kОm/V
sustained power supply is by 24 V
amperage 0,2 A
operating time: with a crowbar switch - 0, 25 s; without a crowbar switch - 1,5…2 s
false response absence by power transfer
escape near-extreme error is about 10%
the device stores functioning data for min 40 s in case of supply disconnection
dielectric resistance digital measurements (from 0 to 9)
supervisory relay may be used for functioning control as well as electric point connection control
overall weight 1,5 kg
SZI is of use as electric main critical insulation resistance control as well as resistance level evaluation with the use of fixed all-digital display; electric main is powered by a single electric power supply.
Designated area: functioning and going up automatic – and communication installations.
Similar equipment: SZI1, SZI2, SZIU.
all types of electric power supply have equal manufacturing
leakoff digital measurements
high fire safety of the device
DC power supply sides insensitivity low effect (force)
low insensitivity dancing by connection voltage – and tasting voltage excursion
there exists the possibility of an in field testing the attention device sensitivity
leakage value in field qualitative assessment without the use of an additory milliamperemeter
application possibility of changing in direction of movements in diagrams
may be used for cable circuits – and signaling, centralization and blocking equipment dielectric resistance control
