• Compliant Standards:

GB/T 20840.1, IEC 61869-1; GB/T 20840.6, IEC 61869-6; GB/T 20840.7, IEC 60044-7; GB/T 20840.8, IEC 60044-8, and special customer requirements.

• Product Overview:

The electronic voltage transformer is manufactured based on the principles of resistive voltage division, resistive-capacitive voltage division, or capacitive voltage division. The output secondary signal is proportional to the voltage of the system being measured, capable of simultaneously providing measurement and protection signals.

The electronic current transformer is manufactured based on the low-power coil (LPCT) principle. A single product can have multiple windings, enabling simultaneous measurement of phase current and zero-sequence current, with each winding meeting the accuracy requirements for both measurement and protection.
