Overview
About the Red Phase 1.5 kVA Earth Current Injection Set (4024B + 4023)
Description
The Red Phase 4024B + 4023 system is a compact, portable earth current injection test set designed for verifying the performance of substation earth grids, neutral earthing systems, and protection relays under controlled fault conditions. Capable of delivering up to 1.5 kVA of output power at variable current and voltage, the set consists of the 4024B switch-mode voltage source (the control unit, with display and keyboard) and the 4023 multi-tap coupling transformer. Together, they enable primary current injection through earth electrodes, ground mats, or structural steel to test current distribution and validate system integrity. The equipment is rugged, field-proven, and widely used by utilities and commissioning engineers.
Features
• Delivers up to 1.5 kVA injection power
• Injection current from 55 A at 26 V (0.5 Ω tap) to 6 A at 236 V (40 Ω tap), selected to suit the earth loop impedance
• Consists of the 4024B voltage source (control unit) and the 4023 coupling transformer
• Suitable for earth grid integrity checks, fault path verification, and relay testing
• True RMS metering of voltage and current

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
Red Phase 1.5 kVA Earth Current Injection Set (4024B + 4023)
What is this test set used for?
It’s designed for earth injection testing, which involves injecting current into an earthing system and measuring the response to assess grid integrity and simulate fault conditions for protection testing.
Can it be used for protection relay testing?
Yes. The unit can simulate earth fault conditions, making it suitable for testing earth fault relays, residual current relays, and verifying pickup thresholds.
How much current can it inject?
It can inject up to 25 A, depending on output voltage and site load impedance. It’s designed for low-impedance, high-current injection typical of substation grounding systems.
What’s the difference between the 4023 and 4024B?
• The 4024B is the switch-mode voltage source and control unit: it ramps the output, meters current and loop impedance, and carries the overload protection
• The 4023 is the coupling transformer: its selectable taps (0.5 Ω to 40 Ω) match the output to the earth loop, from 55 A at 26 V to 6 A at 236 V
Is it portable?
Yes. Both units are compact, ruggedised, and supplied in a transportable configuration suitable for field deployment in substations and switchyards.
What types of tests can I perform?
• Substation earth grid continuity and impedance checks
• Verification of fault current paths
• Relay pickup point testing
• Current distribution across earth electrodes or structures
What’s included in the rental?
• 4024B voltage source and 4023 coupling transformer
• Power and interconnect cables
• Heavy-duty output leads and clamps
• Operation manual and transport case
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.
Do you deliver across Australia?
Yes. We provide nationwide delivery and collection, or you can arrange your own freight.
