1. General introduction

GDVA-402 is a full automatic transformer comprehensive tester developed by GOLDSOL. 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,

2. Advantage

1 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.

2 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.

3 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.

4 320*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.

5 Adapt rotating mouth,easy operation and durable use.

6 Flash Ram inside,prevent data losing from power off.

7 RS232 communication interface,make sure connection of the instrument and PC, triers can control the test and unload the test data through PC.

8 AC220V and AC380V power supply
