HV Tester 25 kV and 25 kV Digital

Portable High Voltage Generator

  • DC and insulation testing of cables, joints, electrical fixtures, etc.
  • High flexibility, thanks to built-in battery
  • Internal discharge facility
  • Available with analogue or digital metering
  • Built-in timer (1 to 30 min)

The HV Tester 25 kV and 25 kV Digital are portable high voltage generators with a variable negative DC output voltage of 0 to 25 kV. They are robust, lightweight, compact and and easy to use. Due to their small size and internal battery, these test systems are ideal for test conditions where no external power supply is available. Capacitive loads, such as shielded cables, are safely and automatically discharged in the case of a breakdown and at the end of testing via the internal discharge facility. Standard HV tester 25 kV comes with analogue meters, additionally Megger offers the HV tester 25 kV with digital metering which allows a more precise reading of the current and setting of the voltage.

These instruments are ideal for testing paper-insulated/mass-impregnated cables according to IEEE 400-2012 and IEC 60060-3, testing electrical equipment according to IEEE 62.1 and IEEE 95, and testing cable sheaths/outer jackets according to IEC 60502/IEC 60229.

Insulation Resistance Tester

Megger BM5200 is a battery powered insulation tester with digital and analogue arc display, designed for high voltage insulation resistance testing in the maintenance and servicing of cables, rotating plant machinery, transformers, switchgear and industrial applications.

DC insulation tests are performed at 250 V, 500 V, 1000 V, 2500 V, 5000 V. Insulation resistance measuring range is 100 k Ω to 1000 G Ω. Automatic discharge for capacitive circuits under test is provided and decaying voltage displayed.

The guard terminal can be used to minimize the effects of surface leakage and hence erroneous measurements when carrying out insulation resistance tests.

  • 1 T Ω, 1.4 mA, 5 kV digital insulation tester with digital and analogue display
  • Five test ranges; 250 V, 500 V, 1000 V, 2500 V and 5000 V
  • Insulation (InS), Polarization Index (PI) and variable timed test (t) modes
  • Selectable DC or AC (including frequency) voltmeter functions
  • Guard terminal to shunt surface leakage currents
  • CATIII 600 V safety rating

High voltage hand-held insulation and continuity tester

The MIT2500 insulation and continuity tester has been designed for motor and cable testing, specialist applications, and electrical testing applications, where operation voltages exceed 1000 V and higher insulation test voltages are needed.

The MIT2500 offers both fixed range voltages of 50 V, 100V, 250 V, 500 V, 1000 V, and 2500 V, as well as a variable range that allows any voltage between 50 V and 2500 V to be “dialed in”. This is supported by the new test voltage feedback control, which maintains the output test voltage to within 2% of the selected range, even when under test.

  • Insulation testing up to 2.5 kV  and 200 GΩ range in a handheld instrument
  • Guard terminal for high resistance accuracy
  • Adjustable insulation test voltage from 50 V to 2500 V
  • Stabilized insulation test voltage
  • Rechargeable options for mains and car charging
  • Single range, faster continuity testing from 0.01 Ω to 1 MΩ
  • Polarization Index (PI) & Dielectric Absorption Ratio (DAR)
  • CAT IV 600 V applications
