Overview
About the Omicron CR 500 Compensation Reactor Accessory
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.
Features
- 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 with a NATA-traceable certificate included with every hire
Common Applications
- 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

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.

How the hire works
Hire terms in brief
After you enquire
We confirm availability, rates and freight in a written quote, valid for the period it states (usually 14 days). An enquiry or quote does not reserve equipment: the hire is booked when your purchase order, signed quote or email acceptance reaches us.
Hire period
Our carrier: up to 72 hours of transit each way is not charged as hire. Hire starts at delivery or 72 hours after dispatch, whichever is earlier, and ends at handover to our carrier or 72 hours before the equipment arrives back, whichever is later. Delay caused by us or our carrier is not charged. For example, dispatched Monday 10am and delivered Wednesday 2pm: hire starts Wednesday 2pm. Routes that normally take longer than 72 hours are marked on the quote. Your own freight: hire runs from handover to your carrier at our office until the equipment arrives back at our office. Collect in person: from collection to return.
Extensions and early return
Contact us before the return deadline to extend; your quoted rates stay fixed and extended hire is invoiced every 7 days. Return early and you pay only for the days used, at the rate band for the days actually hired.
Delivery and returns
Freight for each leg, the handling fee and any express dispatch are on the quote, before you accept. Returns go to the dispatching office named on the quote, by carrier or in person, never by post.
Counter times
Returned to our counter before 9am on a business day counts as the previous day. Collected after 4pm on a business day, hire starts the next day. Weekends and public holidays count as hire days.
Calibration and checks
Supplied in working order with listed accessories, leads and manuals. Each measuring instrument is calibrated, and its current NATA-traceable calibration certificate is available on request. If calibration falls due during your hire, we tell you before dispatch.
Cancelling or moving a booking
Cancel 5 or more business days before dispatch or collection and nothing is charged. With 2 to 4 business days’ notice, the charge is the greater of one day’s hire and 5% of the booked hire; with less notice, the greater of one day’s hire and 10%. You can ask once to move the start by up to 30 days, with at least 2 business days’ notice.
Loss, damage and insurance
The equipment is your responsibility, other than fair wear and tear, from the start of hire until it is back with us, including in transit, up to the replacement value cap shown on the quote for each item. No damage waiver is offered. We recommend you insure the equipment for its replacement value.
Payment and bond
Account customers pay each invoice within 14 days. Without a credit account, or paying by card, you pay the booked hire, freight, handling fee and any bond before dispatch. A bond applies only where the quote states one, and is refunded after return and inspection, less anything owed.

FAQ
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.
Do I need the CR500 for all VT tests?
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
How does it work with the CPC 100?
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.
Can it be used with other test sets?
No. The CR500 is designed specifically for use with the Omicron CPC 100 and is not compatible with other test systems.
Is it difficult to set up?
No. It uses simple plug-and-play connectors and is controlled entirely through the CPC 100 and PTM interface.
What’s included in the rental?
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.
What support comes with the hire?
Each instrument is supplied with the manufacturer’s manuals. If a set plays up, call us and we will arrange a fix or a replacement.
What is the minimum hire period?
The minimum hire is one day. The daily rate steps down for hires of 8 days or more, and longer project hires can be quoted on 1300 730 499.
Can I hire this with the CPC 100?
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.
Do you deliver nationally?
Yes. We provide Australia-wide delivery and pickup or can work with your chosen freight provider.
