GF106 Automatic Electrical Portable Current Transformer Test equipment
Current transformer testing. A fault leading to an open secondary could cause the primary current to overwhelm the insulation, causing the winding to short circuit. GFUVE’s range of current transformer test equipment allows you to construct an in depth test and maintenance programme to prevent problems before they occur.
GF106 Portable Current Transformer Test equipment is mainly used for field testing, it can finish the measurements (M) and protection (P) class CT, PT and TYP class CT. Adopt LCD, self-equipped mini type printer supporting field printing; supporting to use USB flash disk to dump data, with simple and convenient operation.
Current Transformer (CT) & Potential Transformer (PT) Testing.
Customer load test consisting of direct simultaneous measurement of
the secondary current signal of the CT, and the voltage drop across
its terminals. Accurately measuring these signals allows the
calculation of the existing burden on the CT. This burden
measurement is verified against the specification from the CT
manufacturer.
Current transformer testing. Ratio tests under normal load are
achieved by comparing voltage applied to the secondary winding
against the resulting voltage produced on the primary winding.
Current transformer resistance tests inject test voltage to measure
the DC current and calculate the resistance with allowance for
temperature.
FEATURES
- Steady and transient state characteristic tests of various types of CT/PT
- The use of advanced power technology, the test knee point reaches up to 40kV
- No external other auxiliary equipment, stand-alone to complete all test items
- CT test, easy to test, all the tests are using the same wire connection except the load test
- It carries with thermal printer, so it can print test results on site
- Parameters such as knee point current and voltage
- Parameters such as 10% error curve, 5% error curve
- The device can store 3000 groups of test data which would not be lost if the device is power off.
- The data can be displayed and analyzed after the test, or transferred to PC through USB disk and produce a Word file report
- Portability: weight < 12kg
