GUARDIAN 10KVAC Chroma HiPot

New
The GUARDIAN 10KVAC is a HiPot from Chroma. HiPot, or high potential, is a class of electronic test equipment used to verify electrical insulation. Engineers use HiPot-testing instruments on cables, wires, circuit boards, appliances, electric motors, and transformers. As a product ages, its insulation may break down and result in current flow leakage. HiPot testers keep engineers safe from current leakages by detecting gaps and defects in the electronic device. Dielectric Testers, Insulation Testers, and Megohmmeters are similar to HiPot testers. Popular manufacturers include Biddle, Megger, Fluke, Associated Research, Quadtech, Instek, and Slaughter.

Additional Features:

  • AC HiPot Voltage: 100V to 10kV AC, 10V resolution
  • Frequency: 50 or 60 Hz Programmable
  • Output Current to 20mA
  • Programmable Ramp and Test Times
  • Fast Cutoff and Quick Discharge of Device Under Test
  • Programmable Hi/Lo Limits for Pass/Fail Testing
  • LCD Display for Menu Programming and Test Results
  • Internal Storage and Recall of 50 Test Setups, 10 Steps Each
  • Front and Rear Panel Output Connections
  • Front Panel Lockout Prevents Changes to the Test Setup
  • Automatic Offset to Zero Out Stray Leakage Current
  • Remote I/O Interface Included Standard
  • RS-232 Interface Standard
  • IEEE-488 and Printer Interfaces Optional
  • External 8 Channel Scanner Optional

Applications:

  • Production or Compliance Testing of Appliances, Wire, Cable, and Other Electrical Products which have High Leakage Current
  • Testing to Safety Standards which Require or Recommend a 500VA Tester
  • Testing of Electrical Products Requiring the Application of High AC or DC Voltages
  • Testing of Transformers, Coils, and Large Horsepower Motors

The Guardian 10KVAC performs AC HiPot testing only, over a voltage range of 100 to 10,000V AC. With a maximum current output of 20mA, the instrument is capable of testing capacitive devices at high AC voltages. The 10KV unit contains many of the features of the 500VA Tester, including programmable min/max limits, setup storage, and arc detection.

In all cases, both high and low limits are operator programmable for quick, and easy pass/fail testing. These dual limits are essential to ensure that the device under test is actually making contact with the tester. For consistent testing, up to 50 setups can be stored in instrument memory for later recall. An optional high voltage scanner is also available for testing multi-connection devices.
