CR500 Compensation Reactor Test Accessory. Hire from Megavar for capacitive current compensation during high voltage withstand testing in Australia.
Description
Capacitive test objects draw significant reactive current from the CPC 100, which limits the achievable test voltage on capacitive loads. The CR 500 sits in series with the test setup and provides inductive compensation, cancelling the capacitive reactive component. The CPC 100’s voltage source is then free to drive the resistive test current at the required level. The compensation is most often used during tan delta diagnostics with the CP TD1 on high-capacitance plant including generators, motors, cables, transformer windings, and grading capacitors. The same compensation principle supports voltage transformer ratio testing at high voltage on capacitive VTs and CVTs. Megavar holds the CR 500 in its Australian hire fleet for use with the CPC 100 plus CP TD1 on transmission and distribution tan delta diagnostics, generator and motor insulation testing, grading capacitor testing, and capacitive primary plant assessment. Supplied as part of a combined CPC 100 plus CR 500 hire package.
  • Reactive current compensation during tan delta and dissipation factor testing on high-capacitance plant, paired with the CPC 100 and CP TD1
  • Capacitive load compensation up to 500 nF, extending the CPC 100’s effective test voltage on motors, generators, cables, transformer windings, instrument transformers, and grading capacitors
  • Direct integration with the CPC 100 platform, automatically recognised by Primary Test Manager (PTM) software when connected
  • Supports voltage transformer ratio testing at high voltage per IEC 61869 and IEEE C57.13 acceptance criteria as a secondary application
  • Compact form factor matching the CPC 100 footprint for transport and storage
  • Supplied calibrated and traceable to NMI; certificate included with every hire
  • Tan delta and dissipation factor diagnostics on high-capacitance plant (motors, generators, cables, transformer windings, grading capacitors), paired with the CPC 100 and CP TD1
  • Grading capacitor testing on EHV circuit breakers, where the test voltage required exceeds what the CPC 100 alone can supply on capacitive loads
  • Voltage transformer ratio testing at high voltage on instrument transformer commissioning and routine maintenance, particularly for capacitive VTs and CVTs
  • Capacitive coupling assessment on cable accessories where high test voltage is required

Megavar engineers use this unit on commissioning projects across Australia. Hire it from a team that knows it inside out.

Calibration

All Megavar test equipment is maintained under a documented calibration programme. Instruments are calibrated either by external calibration laboratories or in-house against reference standards that are themselves laboratory-calibrated, with measurement traceable to Australian national measurement standards held by the National Measurement Institute. A current calibration certificate is available on request. If your project requires a specific calibration interval, test standard, or documentation for a client submission, tell us at enquiry on 1300 730 499 and we will confirm what applies before you commit.

Frequently Asked Questions
Omicron CR 500 Compensation Reactor Accessory

What is the CR500 used for?

It compensates reactive power when testing capacitive components such as voltage transformers, long cables, or capacitor banks using the CPC 100. This allows the CPC to deliver higher output voltages without waveform distortion.

No. The CR500 is only required when testing VTs or other capacitive devices that exceed the reactive power handling limits of the CPC 100 alone. For small or low-capacitance loads, it may not be necessary

It connects directly to the CPC 100’s output and is automatically detected by Omicron’s PTM software. It supports the CPC by reducing the reactive burden during AC voltage output.

No. The CR500 is designed specifically for use with the Omicron CPC 100 and is not compatible with other test systems.

No. It uses simple plug-and-play connectors and is controlled entirely through the CPC 100 and PTM interface.

The hire includes the CR500 unit, high-voltage rated cables, instruction sheet, and transport case. It can be hired standalone or alongside a CPC 100 system.

Yes. We offer setup support and guidance on when and how to use the CR500 effectively in your CPC test configuration.

The minimum hire is 3 days. Longer-term rental options are available with discounted weekly or monthly rates.

Yes. We recommend hiring the CR500 as an add-on when testing VTs or capacitive loads with the CPC 100 to ensure reliable test results.

Yes. We provide Australia-wide delivery and pickup or can work with your chosen freight provider.
