APPLICATION:
Phasing device and indicator of pole rotation directon in the 50Hz triphase network with the voltage
from 3 to 10kV and of 120o interphase angle.
TECHNICAL DATA:
– Nominal voltage range – 3 – 10kV
– Housing of quqlity PC
– Total length – 24cm
– Weight – 0,35kg
– Phasing device is adjusted to be fitted on the standard insulating stick according to PN-IEC 832
with grooved tip.
Installing the indicator on UDI type stick requires an adjusting tip enclosed in the set.
– Built-in auto-test prevents from using the device with level batteries or with detected defect
– Operating, effieciant phasing device produces shot solitary signals with 2 seconds intervals.
Contact with the voltage is indicated by the continous signal, denoting saving the phase info,
when the info is saved the signal changes for periodical.
Five short signals with interval each 2 seconds inform about saving the phase info when the
voltage is discontinued. The phase info is saved for maximum 25 seconds.
Periodical acoustic and optical signals indicate compatibility of measurred and saved phases.
Continuous acoustic and optical signal indicates incompatilibity of measurred and saved phases.
According to the standard, continuous signal appears also when it is impossible to indicate the
phase clearly, ex. in case of disturbances.
When the phase is saved, touching consecutively two other phases means measuring the
direction of rotation and in effect appropriate LED 5mm puts on with contiuous light.
Short and fast sounds and interchangeable blinking of 5mm LEDs indicate expiration of the
phase memory time and precede automatic switching off the phasing device.
– All featuring signals are strong and easily recognisable.
– Compliant with PN-EN 61481
– The phasing device is powered by 9V batteries.
– The device is delivered in hard case, with battery, manual and warranty card.
