10	280V	2.450
11	300V	2.627
12	310V	2.716

 Note: When primary current-limiting resistor is 201.8kΩ,secondary sampling resistor is 2KΩ,
       primary voltage is 220V, Then , the output voltage is 1.915V±1%.

Electrical Performance Requirement:
1. Frequency Dielectric Strength
  Primary winding and secondary windings 4KV 1mA ,1 min test without breakdown, arcing and other undesirable phenomena.

2. In-turn Insulation Strength
  Open the secondary coil ,a coil through to the rated current and rated frequency to maintain
 a min , no in-turn insulation within the transformer damage.
3. Insulation Resistance 
  Current transformer primary winding and the secondary winding to ground
insulation resistance between≥1GΩ.

4. Appearance Required
   mark clearly and accurately;model specifications marked correct;transformer no surface dirt ;cited needle size, length, location etc. In line drawings.

5. Package and Transport
   Both in dependent of the small package but also the overall package, transportation of productions to ensure that intact ,but also convenient to inventory.

6. Storage
  Current transformer should be stored at room temperature -45~85ºC,relative humidity less than 90%(25ºC) room, and in the air should not cause corrosion of the harmful gases and other harmful media environment.
