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
technical parameter
1. Temperature:
2. Relative humidity
3. Rated Primary Current:5-5000A 5A,1A
4.Rated secondary current:5 1A
5 Accuracy Class 0.05S
6. Allow long-term work under the rated current; More than120A across the core.
Precautions:
1. The current of standard CT and tested CT must be the same in CT calibration.
2. Follow the given wiring diagram strictly.
3. Test whether the load box is accurate or not before calibrating the transformer.
4. Forbid secondary winding opening during the calibration.
5. 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.
6.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.

Distribution board is also called a panel board, breaker panel, electric panel or DB box. Its main function is to divide the electrical power evenly among all the electrical devices. The primary functions also include power generation, transmission and distribution.
Product description: standard current transformer is used as a standard for calibrating current transformers, Used as a standard to calibrate current transformer whose accuracy class is two or more lower than itself. The grounding pole of the machine shell must be grounded. To avoid electric shock, the conductor must be connected to the ground Technical index 1. Temperature: -5-40 2. Relative humidity: 80% 3. Allow long-term work under the rated current; More than 600A across the core. Feature; 1. The current of standard CT and tested CT must be the same in CT calibration. 2. Follow the given wiring diagram strictly. 3. Test whether the load box is accurate or not before calibrating the transformer. 4. Forbid secondary winding opening during the calibration. 5. Select demagnetization before calibration.Short out the secondary winding before cutting off the power when the demagnetization is finished. 6.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.
