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.

The high-voltage electric energy measurement devices of power plants and substations and the electric energy measurement devices of a large number of users are related to the interests of power generation power transmission power supply and multiple parties of users. In order to ensure accurate measurement the inspection must be carried out in accordance with SD109 "Inspection Regulations for Electric Energy Measurement Devices" and DL / T448-2000 "Technical Management Regulations for Electricity Measurement Devices".

Product description

Transformer Standard current transformer are also called precision current transformers, current transformer standards, standard CT and current transformer standards. Transformer standards are divided into current transformer standards and voltage transformer standards. Standard current transformers are used in the error test of transformers. Used as a current transformer calibration standard

Accuracy Class 0.05S
Allow long-term work under the rated current; More than120A across the core.



Precautions

The current of standard CT and tested CT must be the same in CT calibration.

Follow the given wiring diagram strictly.

Test whether the load box is accurate or not before calibrating the transformer.

Forbid secondary winding opening during the calibration.

Select demagnetization before calibration.The wiring diagram is shown in figure 5.

Short out the secondary winding before cutting off the power when the demagnetization is finished.

Principle wiring diagram of CT with large current generator is similar to above diagram. They are the same except the output winding of large current generator and primary winding of transformer are the same one.
