LDM-5/U5

Description

PRODUCT DESCRIPTION

LDM-5/U5

• For cable and transformer testing
• General use measuring impedance designed for the decoupling of the PD current pulses on the PD coupling capacitor, changing in equivalent voltage pulses and forwarding to the PD detector (according to IEC 60270)
• Voltage signal for phase resolved measurements by an internal low voltage capacitor for measuring test voltage and forwarding to PD test equipment
• Output for test voltage value, derived from the coupling capacitor
• No additional HV divider capacitor is necessary
• With up to 2 switches for maximum 4 different coupling capacitances

Measuring impedance, switchable low voltage capacitance (2 switches) Cu = 200nF / Cu + C1 = 2,4μF / Cu + C1 +C2 =20μF

Accessory for PD
