HVA120 Insulation tester

The HVA120 insulation tester by b2hv is a powerfull 0.1 Hz VLF cable test system for testing of medium voltage cables.
 

The following features make the high voltage HVA insulation tester the outstanding cable test system of its class:

• Predefined standard-compliant cable test sequences
• Absolute symmetrical sine wave high voltage
• RMS measurement of output voltage and current
• Measurement of capacitive and resistive load
• Automatic and load dependent frequency selection (0.01 Hz – 0.1 Hz)
• Display of current test time
• Integrated real-time scope function
• Self-explanatory, multilingual software
• Automatic measurement reporting
• Report storage via RS232 or USB
• PC software (b2 ControlCenter) for data analysis and storage
• Flashover detection and switch off
• Flashover voltage measurement
• Time optimized burning mode
• No regular maintenance required

The fully comprehensive safety features of the highvoltage insulation tester guarantees protection for operator and test instrument.

• Short circuit protected output
• 12 kV feedback protection (50 Hz)
• Signal lamps for active / inactive high voltage
• Status display of safety functions
• Dual Discharge Device (DDD®), two integrated and automatic discharge devices
• Main switch with key-lock
• Emergency-off button on front panel

A SINGLE insulation tester for NUMEROUS applications:

• Cables: XLPE , PE, EPR, PILC, etc.
• Capacitors
• Switchgear
• Transformers
• Rotating machines (IEEE 433)
• Isolators
• Bushings

The HVA120 may be expanded with optional devices to a full cable diagnostics system.

The HVA system may then be used for partial discharge and tan delta diagnostics

• PDTD120-2 partial discharge test up to 120kV

• TD120-MC tan delta testing
