Product Description

XHDP-80M · AUTO FREQUENCY VLF

Portable High Precision LCD Digital VLF AC Cable Withstand Voltage Hipot Tester

30 – 80 kV peak

0.1 – 0.01 Hz auto sweep

Up to 10 µF load

The XHDP-80M is the high-capacity member of the family: instead of three fixed frequencies it sweeps automatically from 0.1 Hz down to 0.01 Hz, which lets it hold a stable output on specimens whose capacitance would overload a fixed-frequency set. Load capability reaches 10 µF at 30 kV and 40 kV, 6 µF at 50 kV, 5 µF at 60 kV, and 6 µF up to 50 kV with 4 µF above that on the 80 kV unit.

Units rated 60 kV and below use a single booster; above 60 kV two boosters are connected in series, which keeps each piece light enough to handle and lets either booster be used on its own. Voltage and current are sampled directly on the high voltage side, the loop is closed on both sides so there is no capacitance rise, and the set is fitted with a 150 kV output lead and a large colour touch screen.

Product View

Who This Set Is For

The 80M is specified where the specimen is large enough that capacitance, not voltage, is the limiting factor.

Power plants testing generator stator windings and large motors, where a single phase can present several microfarads.

Cable networks with long 35 kV runs, where the capacitance per phase exceeds what a fixed-frequency 1.1 µF set can carry.

High voltage laboratories and research facilities that also need dielectric loss, insulation resistance and partial discharge measured alongside the withstand test.

Because the frequency sweeps automatically, the test report should state the frequency actually used at each step - it is part of the result, not an operating detail.

Key Features

Automatic frequency sweep from 0.1 Hz to 0.01 Hz, so the output stays stable as specimen capacitance rises.

Load capability up to 10 µF on the 30 kV and 40 kV units, 6 µF at 50 kV, 5 µF at 60 kV and 6 µF / 4 µF split at 50 kV on the 80 kV unit.

Single booster up to 60 kV, two boosters in series above that, with each booster usable on its own - one set, several duties.

Voltage and current sampled directly on the high voltage side, with 0.1 kV and 0.1 mA resolution and 3 % accuracy.

Closed-loop negative feedback control on both sides, so the output has no capacitance rise effect.

150 kV rated high voltage output lead, and protection against over-voltage, over-current and sudden voltage or current change with a response under 20 ms.

Colour touch screen with waveform display, plus dielectric loss, capacitance, insulation resistance and partial discharge measurement added to the withstand test.

Compact integrated version for 30 – 60 kV at 35 kg and 400 × 300 × 500 mm, for crews that want the whole set in one case.

Frequently Asked Questions

Q1.How does the automatic frequency sweep work in practice?

The instrument starts at 0.1 Hz and reduces the frequency as far as 0.01 Hz when the specimen capacitance demands it, so the output stays within the set's capability without the operator selecting a frequency by hand.

Q2.How much capacitance can the 80 kV unit carry?

6 µF up to 50 kV and 4 µF above 50 kV. The 30 kV and 40 kV units carry 10 µF, the 50 kV unit 6 µF and the 60 kV unit 5 µF.

Q3.What is the advantage of two boosters in series?

Each booster stays light enough to handle - 25 kg for the first stage and 45 kg for the second on the 80 kV unit - and either one can be used alone for lower-voltage work, so a single purchase covers more than one test class.

Q4.Can dielectric loss and partial discharge be measured during the test?

Yes. The 80M adds measurement of dielectric loss, capacitance, insulation resistance and partial discharge alongside the withstand test, which is why it is used where a full insulation assessment is required rather than a pass or fail only.

Q5.Why must a variable-frequency generator be used in the field?

The supply is 230 V ± 5 %, 50 Hz. A conventional generator whose speed wanders will upset the boost process and can damage the instrument, so a variable-frequency generator is required when mains power is not available.

Η συσκευή XHDP‑80M δοκιμής υπερβολικά χαμηλής συχνότητας έχει εξαιρετική απόδοση για την ομάδα διανομής μας. Πραγματοποιήσαμε δοκιμές αντοχής σε υπόγεια καλώδια 20kV στον υποσταθμό Κερατέας κοντά στην Αθήνα. Η λειτουργία με οθόνη αφής είναι εύκολη, η προστασία ενεργοποιείται γρήγορα και οι μετρήσεις παραμένουν ακριβείς ακόμα στη μεσογειακή ζέστη. Ανθεκτική κατασκευή για εργασίες πεδίου, μειώνει σημαντικά τον χρόνο προετοιμασίας των δοκιμών. Συνιστάται ανεπιφύλακτα για τα συνεργεία ηλεκτρικής ενέργειας στην Ελλάδα.
