High-voltage measurement equipment

HVM 2001, HVM 2003

The high-voltage measurement instruments HVM 2001 / HVM 2003 consist of a measuring amplifier with digital display for universal use, a built-in high-voltage divider for direct measurement up to 10 kV / optional 20 KV and an external input for an external high-voltage divider, HVT***RCR, for measurement and display of voltages up to 200 kV.. The high-voltage measurement system HVM 2001 is designed for measuring ac- and dc- voltages. The high-voltage measurement system HVM 2003 allows in addition measurement of the peak value of lightning and switching pulse voltages. Optionally the unit can be delivered with a DKD calibration certificate. Technical specification: HVM 2001 HVM 2003

Broad-band High-voltage Dividers for HVM 2001, HVM 2003 HVT 120 RCR, HVT 240 RCR The Broadband high-voltage divider HVT 120 RCR / HVT 240 RCR are state-of-the-art measuring equipment with excellent high-frequency transmission characteristics. The high-voltage impedance consists of a precise metal film resistor and a high-voltage capacitor with series damping resistor in parallel. The measuring cable with the termination network is an essential part of the divider. The

termination network can be adjusted for an input impedance of 1 M // 10 - 30 pF of the unit connected. Technical specification HVT 120 RCR HVT 240 RCR max. Input voltage : DC voltage 120 kV= 240 kV=
