faq
Q:1.What is JDZ10-10 voltage transformer?
A:JDZ10-10 is an indoor, single-phase, epoxy resin cast voltage transformer, designed for 10kV power system. It steps down the primary voltage to 100V for measurement and metering purposes.
Q:2.What is the difference between JDZ10-10 and JDZX10-10?
A:JDZ10-10: Two windings only (primary + secondary). No residual winding. Used for voltage measurement and metering. Cannot detect earth fault.
JDZX10-10: Three windings (primary + secondary + residual/zero-sequence winding). The "X" means residual winding. Used for insulation monitoring and earth fault protection.
Q:3.What is the insulation level?
A:Insulation level is 12 / 42 / 75 kV
Q:4.What is the maximum output?
A:It's typically 200VA, which means the transformer can withstand short-term overload without overheating.
Q:5.Where is JDZ10-10 used?
A: It's widely used in: 10kV switchgear (KYN28-12, XGN, etc.)
Voltage measurement panels;Metering cabinets (without earth fault monitoring requirement);Power distribution rooms, industrial plants, commercial buildings
Q:6.What is the minimum order quantity (MOQ)?
A:MOQ is 10 pieces for standard models.
