Megger HVB10 High Voltage Bridge - Optional Audio Frequency (HVB 10-1-AF)

The Megger HVB10 is a highly accurate high voltage (HV) bridge designed to locate cable and sheath faults, perform sheath testing, and pinpoint sheath faults. It is particularly suited for long HV cables.

With its top resolution, intermittent fault detection function, and load adaptation for faster cable charging, the HVB10 is an indispensable tool for all utilities that want to reduce downtime and facilitate the repair of power in, for example, pilot and communication cables.

The HVB10 has two different methods for fault locations, a standard mode, and a high-accuracy mode.

The standard mode provides good results for typical sheath faults with fault resistances of up to some hundreds of kilo Ohms and shieldS cross sections in the range of 25 to 50 mm2. This measurement is typically done in an app within 30 seconds

The high accuracy mode takes approximately 1 minute for the algorithm to complete but will use the full potential of the measuring and control circuits of the instrument. Thus, it is ideally suited for pre-locating difficult, high-resistive faults (e.g., in the inner insulation of PILC cables). An intermittent fault detection algorithm is applied to gain a result under even worse conditions with sparking faults. An Audio Frequency option is available.

Key Features

• Top-class measurement and accuracy
• Automatic test sequence
• Bi-polar pre-location for the elimination of external influences
• Detection and indication of wrong connections
• Only one high-voltage connection cable
• Completely independent of the parameters of auxiliary lines
• Easy Go operating system

1. Touch-screen display
2. USB port
3. On/off push-button
4. HV “interlock” key switch
5. “HV ON” push-button
6. “HV OFF” push-button
7. Rotary encoder
8. Protective earthing connection
9. HV output
   

   The HVB 10 generates a dangerous voltage of up to 10 kV during HV operation. This is induced into the HV connection cable through the HV output.

10. Power supply socket with fuses F1 / F2 (2 x M6.3/250)
11. 12 … 24 V DC charging socket
12. Emergency off button
13. Socket to connect the external safety device
