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.

The test transformer calls the booster, it is the basic test equipment used by the power station, supplying and distributing the electrical power system and the scientific research unit. Which used in the insulated intension test on all kinds of electrical products, electrical equipments and insulated materials, testing the insulated level of products, discovering the insulated objection of quizzee, scaling the capacity burdened voltage
Transformer calibrator is a new automatic instrument. We apply advanced electronic technology in the design. By directly decomposing the error signal, it is able to display the percentage, phase error and orthogonal error statistically. It s quick and energy saving. And it s especially good for live testing due to its cute dimension and light weight.

Using Methods and Attention Matters
1.Check the test transformer measuring winding rated output voltage, and make it match the operation box correctly.
2. Connect the line between test transformer and operation box according to the wiring diagram.
3. Switch on the power supply, then close the knife switch, and the power indicator light, finally set the work time of relay.
4. Make the pressure regulator display zero, press the start button, the clockwise rotation of the hand wheel, until it reaches the required value.
5. Start the timing switch, timing begins, the electric bell will alarm automatically when it reaches the setting time(artificially controlled time if there is on alarming function), then break off the timing switch.
Q&A:
What is the difference between a control box and a box-type transformer
The control box has only control functions. It is a control unit. Its main function is to issue instructions to control the rapid breaking of the circuit breaker in the box substation; it is a component in the box substation.
The box-type transformer generally refers to the box-type substation, which integrates the functions of power transformation, power distribution, control, and protection.
Designed to measure the winding resistance of transformers, Inductors, generators, motor windings, Tap Changers, Bus bar contacts Etc.
Features
- Built-in carry case for convenient portability
- available in current capacity 10AuP, 25AuP (additional cost) and 50AuP (additional cost)
- Simultaneous measurements of voltage & current
- Protection against inductive kickback & discharge
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.
