①.Winding requirements
Primary: Lead out by copper conductor.
Secondary: Lead out by UL1569 #24 black and red wires.
②.Insulation strength between turns
Keep the secondary coil open, then input rated current and frequency to primary coil for one minute, the insulation between turns of CT should be without any damage.
③.Insulation resistance
The insulation resistance between primary winding and secondary winding:≥1000MΩ
④.Frequency Insulation strength
The primary winding to the secondary winding can undertake frequency AC 4000V and will not be penetrated for one minute by 1mA creepage.
⑤.High and low temperature is between -40~85℃,96hours . All parameters and electrical performance Not failed.
Appearance
The label of the CT should be correct and the appearance of the CT Should be clean.
The specifications, length, color and position of wires must be the same with the drawing.
Package and Shipment
The packing should guarantee the goods in a good state during transportation and easy to count.
Storage
Air humidity is less than 90%(25℃) and any eroding gas or other harmful gas should be avoided. www.sh-smarttechnology.com |
