Frequently Asked Questions
Q What is the difference between the JDZ18-10R and JDZ18-6R voltage transformer models?
A The main difference lies in their rated voltage ratios. The JDZ18-10R operates at 10000/100/220V with a rated insulation level of 12/42/75, while the JDZ18-6R operates at 6000/100/220V with a rated insulation level of 7.2/32/60. Both models share the same accuracy class outputs and limit output of 500VA.
Q What accuracy classes are available for this voltage transformer?
A This voltage transformer supports four accuracy classes: 0.2 (20VA), 0.5 (30VA), 1 (60VA), and 6P (50VA), making it suitable for both metering and protection applications in ring network cabinets.
Q What is the maximum limit output of the JDZ18 series voltage transformer?
A The maximum limit output for both the JDZ18-10R and JDZ18-6R models is 500VA, ensuring reliable performance under demanding load conditions.
Q Is this voltage transformer specifically designed for ring network cabinets?
A Yes, the JDZ18-R series voltage transformer is specifically engineered for use in ring network cabinets (RMU). Its compact outline dimensions and wiring configuration are optimized to fit the structural requirements of ring network switchgear.
Q What does the rated insulation level indicate for these transformers?
A The rated insulation level represents the transformer's ability to withstand voltage stresses. For the JDZ18-10R, the level is 12/42/75 (kV), indicating the rated voltage, power frequency withstand voltage, and lightning impulse withstand voltage respectively. For the JDZ18-6R, these values are 7.2/32/60 (kV).
Q Can the wiring principle diagram be used for both JDZ18-10R and JDZ18-6R models?
A Yes, the wiring principle diagram shown applies to both the JDZ18-10R and JDZ18-6R models. The secondary winding connections and terminal configurations follow the same wiring layout, with the primary voltage rating being the key differentiator between the two models.
