Ac Transformer Ratio Tester

Introduction AC transformer ratio tester is an innovative product are mainly applied to change than group test transformer, PT and CT polarity test, test speed, high accuracy. Technical Indicators Working power supply AC22050/60 HZ Instrument weight 3.8 kg Instrument dimension 325 mm L 225 mm W 125 mm H Use of temperature -10 50 Relative humidity 90 No dew Functional Characteristics It has the function of blind measurement, that is, to perform variable ratio and group test when there is no connection between high and low voltage. Based on the test of conventional transformer, Z-type transformer and PT sample, the polarity test function of CT variable ratio is added, and the application field is wider Wide range and high accuracy, the variable ratio measurement range can reach 10,000, and the test accuracy can be guaranteed 0.3% when the maximum value is 10,000. It has perfect protection functions such as reverse connection protection and output short circuit protection.

Product description The current booster is used on checking current transformer,to be the power source supply once current for current transformer or to be other 50Hz single phase current source device. Technical index Temperature Humidit Capacity: 20kVA Specification Weight: 75Kg Allow long-term work on the rated current Allowable overload 1.5 times,30 minutes of continuous work. Feature This PSLLQ is make up of input Winding(220V), output winding below 100A and CXRZ. Output current indicated on the nameplate is defined the rated current that through winding allow to pass.When CX many circles, the rated current its permitted to pass through will inversely decline. The value which ouput capcity divided by product of output current and each circle voltage was the biggest circle number allowing. The current booster is designed to provide the primary current power supply for the current transformer when verifying the current transformer or as other 50HZ single-phase power equipment. The current booster for transformer verification is suitable for power departments such as power testing, power measurement, and power maintenance. The current booster is developed and produced according to the industry standard of transformer error testing, and is used as a current transformer to verify the primary current of the current transformer. The output current can be customized according to customer requirements. The lifter is equipped with casters for easy on-site movement.

Product Characteristics 1. Applicable to transformers connected in Z type. 2. Two output voltages are optional and applicable to transformer whose zero-load current is relatively high. 3. Have wide testing range and the highest transformation ratio may reach 10000. 4. Automatically calculate tap position. 5. Fast speed which is only 18 seconds for three-phase. 6. Favorable repeatability. 7. Automatically save 99 data at most. 8. Flexible data processing including retrieval print transfer to U-disk delete and upload to PC computer for testing. 9. Have transformer short-circuit protection and interturn short-circuit protection functions. In case of short circuit relevant information will be displayed on the LCD screen in characters. 10. The upper computer could control the whole testing process save data . 11. Struction manual is attached to the tester providing convenience for users. 12. The tester is small and is a little bigger than a piece of A4 paper. 13. The tester is light and its weight is only 6.9kg.

Product description The Transformer short circuit impedance tester comes with an adjustable power output. Regardless of single phase or three phase transformers, only one connection is required, and the instrument can complete the measurement of all winding pairs. The test and connection are simple.
