S_total = ΣS_instrument + I₂² × (ρ × 2L / A)
Q : What is the insulation level of this CT?
R : The insulation level is 24/65/125kV and 18/55/105kV, meaning for 24kV system, power-frequency withstand 65kV and lightning impulse 125kV peak; for 18kV system, 55kV and 105kV respectively.
Q : Can this CT be used outdoors?
R : No, it is designed for indoor use with epoxy resin insulation, suitable for CGIS switchgear.
Q : What are the available accuracy classes?
R : Accuracy classes include 0.2, 0.5, and 6P(3P) for metering and protection.
