GDVA-402 Current Transformer CT PT Testing Equipment
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.
