AI>>> - Autonomous independent overcurrent protection protects objects against consequences of
short-circuits in the absence of device supply voltage.
DAR - Fault recorder used to record analog-digital signals with sampling frequency 2 kHz.
CDAR - Criterion recorder used to record analog-digital signals with sampling frequency 50 Hz.
PQA - Power quality analyzer used to assess the quality of energy at the protected facility.
SLOG - System log. Stores time-and-date stamped device operation logs i.a. user logging, last
modification of set points, control commands.
UPS - Ensures sustaining full functionality of the device for 60 s following voltage decay or up to
200 s with display backlight off.
RPS -The solution that allows installation of two independent power supply units in the bay
controller, making up redundant power supply system.
SC – Self check, monitoring of internal states of the device.
MAC – Manual algorithm check simulates measurement values and allows verification of correct
operation of an algorithm.
CBD - Circuit breaker diagnostics is used to determine critical parameters of circuit breaker/contactor
during its operation.
CCT - Cumulated Current Test monitors the value of cumulated current for each phase.
CBCT - Circuit Breaker Control Test monitors the integrity of coil control circuits and auxiliary voltage.
HVT - High Voltage Test monitors the condition of cable insulation, using high voltage, before
energizing the cable.
PAT - Protections and Automatic Functions Test verifies correct operation of protections and
automatic functions, using external testing systems.
Communication and arc detection fibre optic cables, sealing caps, fixing elements, hardware access
key, grounding copper braid, mini USB cable.
Accessories available for MUPASZ devices can be found on the website energetyka.itr.org.pl.
