I.General introduction
GDVA-402 is a full automatic transformer comprehensive tester.
The tester can finish:
- CT/PT volt-ampere characteristic curve test,
- CT/PT Polarity test,
- CT/PT Transformation ratio test,
- automatically calculate error curve of any CT point,
II.Characteristic of GDVA-402:
- The instrument is easy to operate.
- Complete computerize device and high performance CPU,no need manual
work,it finishes test automatically,which prevent person from high
voltage circuit.
- Large output. Maximum output voltage of volt-ampere characteristic test reaches
to 1000V,Maximum output current of transformation ratio test is
600A,output capacity of internal voltage regulating machine is
5KVA.
- Optional accessory includes external join to voltage raising
machine ,current raising machine and voltage regulating
machine.Maximum voltage of external voltage raising machine is
2000V,3A;Maximum current of external current raising machine is
1000A;Maximum output of external voltage regulating machine is
1500V,20A.You can have a CT test of reach up to 500KV,1A when using
external voltage raising machine.
- 320*240 Large screen,it can display volt-ampere characteristic curve directly when the
test is finished.It can print curve and result anytime with
micro-printers of the tester.
- Adapt rotating mouth,easy operation and durable use.
- Flash Ram inside,prevent data losing from power off.
- RS232 communication interface,make sure connection of the instrument and PC,triers can control
the test and unload the test data through PC.
- AC220V and AC380V power supply
