Capacitive Voltage Transformers NDKM-500 UHL1

The NDKM series capacitive voltage transformers are designed to transmit measurement signals to measuring devices, protection systems, automation, signaling, and control in AC networks with industrial frequency at voltage classes of 110, 150, 220, 330, and 500 kV.

Key Features:

• Operate on electromagnetic induction to convert AC voltage levels while maintaining constant frequency.
• Consist of a capacitor voltage divider and an electromagnetic unit (EMU).
• Can be used as coupling capacitors for high-frequency communication channels, relay protection, and emergency automation with connection filters up to 1000 kHz.
• Not susceptible to ferroresonance.
• Wide range of nominal powers with accuracy classes up to 0.2, eliminating the need for load resistors.
• Digital output for transmitting measurement information to modern digital devices and high-frequency transient recorders.
