Description
ZJB**2 micro-computer relay protection tester can
do calibration and test for all current breaker and protection
device, it is necessary and essential test device for power
station, grid company and other electrical units.
Features:
Standard *-phase voltage and
*-phase current output: Conveniently do all
kinds of combination output and all typies of protection test. Each
phase voltage output **0V，*-phase current output **0A，4th-phase
voltage Ux is multi-functional voltage item，can set as 4 kinds of
3U0 and inspect synchronous voltage，or any one of voltage status
output.
Convenient single
operation: Operate by a rotating mouse and display through
big LCD. Can finish the verification of most tests, and can do
verification of all typies of relay and micro-computer protection,
and simulate all kinds of complicated
transienceã€Permanenceã€transformation fault and do whole
group test. Operate conveniently as soon as startup.
Dual-operating mode, run
connecting with computer: Can do the verification for all
kinds of big, complicated and high automation works through
operating software of Windows platform，conveniently test and scan
all kinds of protection setting value，In time save testing data,
display vector graphics，draw fault wave form，online printing
reports.
Strong software
function: Can do all kinds of big automation and
complicated calibrating works, such as three phase differential
test, factory electrical quick cut off, automatic bus transfer,
line protection/auto-reclosure and so on, easily tets and scan each
pretection settings, do fault recovery, real-time store test data,
show vector graphic and online printing report.
Rich switch value
contacts: *-road contact input and *-pair space contact
output. Output contact is compatible with space contact and
0～**0V protential contact, intelligently auto indentify. Input
and output contact can be extended by customer\' s
requirements.
Big screen
LCD: **0×**0 lattice high pixel and high
quality LCD, on screen controlling the whole process and settings,
clearly and easily.
Self-protection: perfect
design and thermal structure, nice protection and power software
startup, has certain self-diagnosis and interlock
function.
Independent and dedicated DC
source output: *-road **0V and **0V adjustable DC source
output.
High cost
performance: united product design over
multi-industry, absorb new and developed technical results. It has
good performance with big size equipment, and low cost with small
tester.
