LMZ Series Fully Insulated Instrument Low Voltage Zero Sequence Current Transformer
Suitable for installation on the three-phase casing of ring network switchgear and main column switch, for the measurement and protection of three-phase current and zero sequence current, and can also be used for the measurement and protection of zero sequence current of multiple cable circuits.
The core and secondary winding of this series of zero sequence current transformers are made of high quality epoxy resin cast in vacuum in a flame-retardant plastic case. It is moisture-proof, stable and maintenance-free.
Product Advantage
1. zero-sequence current transformers provide accurate measurements of ground fault currents, allowing for quick detection and isolation of faults to prevent damage to equipment and ensure safety. Secondly, they are compact in size and easy to install, making them a convenient option for various applications. .
2. zero-sequence current transformers have a wide operating range and can handle high currents, making them versatile and reliable in different settings.
3. zero-sequence current transformers offer excellent linearity and low phase shift, ensuring precise and consistent measurements.
4. zero-sequence current transformers are cost-effective and energy-efficient, providing long-term savings for users.
