current transformer LMZ1D-0.66

current transformers usually follow certain naming rules, and each part of the LMZ1D-0.66 has its specific meaning:

· L: "current" transformer
M: "busbar" type (or "through" type)
· Z: "cast" molding (with epoxy resin casting, with good insulation and moisture resistance)
· 1: Design serial number or serial number
D: "D" usually stands for "with protection level" or specific function, but in this context is more often referred to as "increased capacity" or "special design", specific reference to the manufacturer's data. It also sometimes stands for "single turn".
· 0.66: The rated insulation voltage is 0.66 kV(660V), indicating that it is suitable for low-voltage systems.
Main use
1. Electric energy metering: Connect the electric energy meter to measure and calculate the electricity consumption. An accuracy of the order of 0.5 or 0.5s is usually used.
2. Current measurement and monitoring: connect ammeter, power meter and other indicating instruments to display real-time current on the panel of power distribution cabinet.
3. Relay protection: connect relays, comprehensive protection devices, etc. When a fault such as short circuit or overload occurs in the line, the signal is provided to make the protection device act and cut off the fault circuit. Usually 10P10 or 10P5 grade is used.
4. System monitoring: provide current signals for reactive power compensation controllers, intelligent power meters and other equipment.
