Overview
About the Omicron CT Analyser Set
Description
The CTA (Current Transformer Analyser) from Omicron is a dedicated testing system for verifying the performance and accuracy of current transformers (CTs) in protection and metering systems. A standalone secondary-injection instrument, the CT Analyzer performs fully automated CT testing according to IEC 61869-2 and IEEE C57.13 standards. It performs ratio, burden, polarity, excitation (knee point), and saturation tests with high precision, offering fast and reliable assessments during commissioning and maintenance. With built-in software automation and reporting via Omicron's PTM platform, the CTA is an essential tool for ensuring CT reliability in substations and industrial networks.
Features
• Automated CT testing from a standalone instrument with its own source and controller
• Tests ratio, phase displacement, burden, polarity, excitation, and saturation
• Compliant with IEC and IEEE standards for CT performance
• Fast, repeatable test sequences with minimal manual intervention
• Suitable for protection and metering class CTs
• Requires the CT primary de-energised and isolated, and the secondary isolated from its burden, before testing
• High measurement accuracy for both low and high burden CTs

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 CT Analyser Set
What does the Omicron CTA test?
The CTA performs a complete suite of current transformer tests, including ratio, burden, polarity, phase displacement, excitation curve, and saturation point.
Do I need the CPC 100 to use the CTA?
No. The CT Analyzer is a standalone instrument with its own source and controller; it does not need a CPC 100.
Is the CTA suitable for protection and metering CTs?
Yes. It can test both protection-class and metering-class CTs with high accuracy, whether installed in switchgear or on transformers.
What standards does it comply with?
It supports testing in accordance with IEC 60044-1, IEC 61869-2, and IEEE C57.13 standards for CT verification.
Can it test CTs on-site?
Yes. The CTA is designed for use in substations and industrial switchrooms. It is portable and rugged, making it suitable for substation environments. Testing is carried out with the CT primary de-energised and isolated and the secondary isolated from its burden.
Does it provide automated test reports?
Yes. The system integrates with Omicron’s PTM (Primary Test Manager) software, allowing automatic testing, result analysis, and PDF reporting.
What’s included in the rental?
The rental includes the CTA unit, connection cables, current clamps or probes, and transport case. Customer to supply own laptop with Omicron CT Analyzer Suite installed.
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’s the minimum rental 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 the CTA and CPC 100 together?
Yes. We offer package deals for bundled CPC 100 and CTA hires, perfect for transformer and CT testing projects.
