Overview
About the Omicron CMC 356 Universal Relay Test Set
Our protection commissioning teams use the CMC 356 weekly on transmission relay testing across the NEM.
Description
The CMC Advanced Secondary Injection Test Set is a multifunctional relay test and simulation system designed for comprehensive testing of protection relays, energy meters, and substation control systems. Widely used in substations and industrial facilities, it allows precision testing of current, voltage, frequency, and timing across a wide range of protection schemes. The CMC system can perform both manual and automated tests and is compatible with testing software such as OMICRON’s Test Universe and PTL. With high output accuracy, flexible configuration, and advanced simulation capabilities, the CMC series is the benchmark for secondary injection testing in modern power systems.
Features
• High-precision secondary injection of current and voltage signals
• Test single- and three-phase protection relays (overcurrent, distance, differential, etc.)
• Outputs AC/DC voltage and current with high stability and accuracy
• Time synchronisation and measurement for relay timing verification
• Manual and automated testing modes via Test Universe or Test Universe software
• GPS time synchronisation via the Omicron CMGPS 588 accessory (separate hire) and IRIG-B sync support (model dependent)
• Ethernet and USB connectivity for data handling and test control
• Portable and rugged design for field and lab applications
• Compatible with IEC 61850 and conventional protection schemes
• Supplied with test leads and hard carry case. Customer to supply own laptop with Omicron Test Universe installed.

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.
