HVA90 Insulation tester

The HVA90 insulation tester by b2hv is a portable 0.1 Hz VLF cable test system for the testing of medium voltage cables.

With its weight of 127 kg the hipot tester provides an excellent power-to-weight-ratio. 

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

• Predefined standard-compliant cable test sequences
• 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 ultra fast 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
• 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 HVA90 may be expanded with optional devices to a full cable diagnostics system.

The HVA system may then be used for tan delta measurement

• TD90 tan delta testing

or partial discharge measurement

• PD90-2 partial discharge test up to 90kV
