Overview
About the HVA 28kV VLF Test Set with Integrated Tan Delta
Description
The HVA 28 is a compact, portable Very Low Frequency (VLF) high voltage test set with integrated Tan Delta (TD) diagnostic capability, designed for testing and condition assessment of medium-voltage cables. Operating at 0.1 Hz sinusoidal output, the HVA 28 delivers reliable withstand testing up to 28 kV peak (20 kV rms) and simultaneously provides Tan Delta measurements to detect insulation degradation. This dual-function tester enables both pass/fail pressure testing and diagnostic evaluation in a single unit. It is ideal for commissioning, maintenance, and troubleshooting in distribution networks, substations, wind farms, and industrial facilities.
Features
• VLF testing up to 28 kV peak / 20 kV RMS sinusoidal output, covering the IEEE 400.2-2024 installation, acceptance and maintenance test levels for 11 kV cable systems and the installation level for 15 kV class
• Integrated Tan Delta (TD) diagnostics for insulation condition assessment
• Suitable for MV cables rated up to 11 kV class (15 kV class at the installation test level)
• 0.1 Hz sinusoidal output for IEC 60502-2 and IEEE 400.2 compliance
• Fully automated test sequences with real-time TD analysis
• Lightweight and portable (approx. 15 kg) with rugged casing
• Battery-free operation via standard mains power
• Internal memory for results storage and USB export
• Bright, high-contrast display and intuitive controls
• Supplied with HV test lead set, ground cable, and carry case

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.

What is the HVA 28 used for?
It is used to test medium-voltage power cables using VLF AC voltage. It performs withstand testing and simultaneously evaluates the condition of cable insulation using Tan Delta diagnostics.
What is Tan Delta (TD) testing?
Tan Delta is a diagnostic method used to assess the quality and ageing of cable insulation. A higher TD value typically indicates moisture, contamination, or other degradation in the insulation.
What voltage can it test up to?
The HVA 28 outputs up to 28 kV peak (20 kV rms) at 0.1 Hz, which covers the IEEE 400.2-2024 test levels for 11 kV class cables and the installation level for 15 kV class.
Is it compliant with international standards?
Yes, it complies with IEC 60502-2 and IEEE 400.2 for VLF and TD testing.
Can it store test results?
Yes, the unit includes internal memory and allows results to be exported via USB for reporting and analysis.
Is it portable and easy to use?
Yes. The unit is compact, lightweight, and housed in a durable field case. It features an easy-to-use interface and runs from standard mains power with no need for batteries.
What applications is it suitable for?
The HVA 28 is commonly used in cable commissioning, maintenance programmes, substation work, wind farm installations, and cable fault troubleshooting.
What’s included in the rental?
The rental includes the HVA 28 test unit, HV and ground leads, carry case, and user guide.
