CT PT Test Set

HM6060 ct pt test set is a fully automated CT / PT tester, and is a specialized testing equipment of relay protection and HV insulation. The tests can be finished including: CT volt-ampere characteristics test, CT ratio polarity test, CT polarity test, CT primary current injecting test, PT volt-ampere characteristic test, PT ratio polarity test and PT polarity test, automatic calculation of inflection point voltage and current values, ratio contrast value, 5% or 10% error curve values, etc..

The CT PT Test Set uses imported core components, strict manufacturing process to ensure stable and reliable; instrument panel with ergonomic design, simple operation, one operator can complete all test works, powerful software, automatic calculation and get test results; with U disk dump function, combined with the PC software to generate comprehensive test reports, simple and highly effective data management, reduce the work burden of operators; with micro-printer, can real-time print test data and curves. This CT PT Test Set is a full-featured and specialized testing equipment for laboratory and field testing.

1. Safe and convenient to operate: High-degree automation equipment, auto-complete setting test, and get the test results and curves. The test personnel need not touch the tested equipment, far from high voltage circuit ,to ensure their personal safety.

2. Full-featured: CT volt-ampere characteristics test, CT ratio polarity test, CT polarity test, CT primary current injecting test, PT volt-ampere characteristic test, PT ratio polarity test and PT polarity test, automatic calculation of inflection point voltage and current values, ratio contrast value, 5% or 10% error curve values, and real time save and print test records and date, convenient for user to document the test report.

3. High output capacity: the maximum output voltage for volt-ampere characteristic tests up to 1000V, external booster can be maximum increased to 2500V, variable ratio test and a flow-through test maximum current 600A,the output capacity of equipment is 5KVA, can do the volt-ampere characteristic test of 500kV,1A current transformers

4. Friendly man-machine interface: large-screen 320 × 240 dot matrix character graphical interface, graphics are clear, and aesthetic; using high-performance rotating mouse, easy to operate and long service life; equipped with micro-printer, can real-time print test data and curves.

5. Built-in Flash memory device can store large amounts of test data, which will not be lost after power off. When the filed tests finished, people can check and print the tests results indoors.

6. U-disk dump: support U disk to dump test data, through PC to read, easy to operate.

7. PC with powerful software, beautiful outlook, easy to operate, can save and print the test results, convenient to manage the test data.

8. Apparatus can achieve AC220V and AC380V adaptive power supply. When the AC power input terminals connected to AC220V voltage, AC voltage output is 0 ~ 600 V, when the input terminals to AC380V voltage, AC voltage output is 0 ~ 1000 V. Users can choose according to actual needs.

Instrument panel as shown in Figure 1.3, the figure marked as follows:

The ct pt test set is equipped with power input jack (with 2A fuse) and cooling fans on the side plate. The power jack can stａnd AC380V and AC220V input voltage. The equipment will make self-adaptation according the input power.

1. Why do volt ampere characteristics test, the voltage rise less than 1000V, only more than 600V, with prompt "regulator reach the maximum value, returning"?

Answer: this instrument is AC220V or AC380V adaptive power supply. When the AC220V voltage is connected, the output of the AC voltage is 0~600V, and the output of the AC voltage is 0~1000V when the voltage of the AC380V is connected.

2. Why do CT ratio test, current up to 400A, the voltage boosting is slow and the instrument there with abnormal sound?

Answer: for CT ratio test if the current need to rise to more than 400A, AC380V voltage is needed, otherwise it will appear afore-mentioned phenomena, serious can burn instrument.

3. When does CT ratio test, why primary side with current, secondary side no current?

Answer: In ratio test, if primary side with current and the secondary side without current, use multi meter to test the CT ratio secondary side, if secondary side is circuit connected: ①Please check if the CT secondary side is open circuit. ②Please check the phase of secondary side is same with primary side.

4. Why printer without display

Answer: this may be paper backward, take out the printing paper and install another side. The red indicator of the micro printer light on indicates that the printing paper is out of the need to replace.

5. How to get the voltage value related to any point current?

Answer: this function needs the support of the host computer. First use the instrument measure volt ampere characteristic curve, and the use of U disk functions data load to "transformer multifunctional automatic test software", choose one CT volt ampere characteristics test data, at " data volt ampere curve any point computing" function box, input your wanted to view the current value and click calculate voltage value, to calculate the current value corresponds voltage value.
