Product Description

XHDP-50 · 0.1 Hz VLF TEST SET

XHDP-50 VLF Cable Hipot Tester AC 0.01Hz Withstand Voltage Test and Customization

50 kV peak output

0.1 / 0.05 / 0.02 Hz

Controller 4 kg, booster 40 kg

The XHDP-50/1.1 is a 0.1 Hz very low frequency withstand voltage generator rated 50 kV peak, built for the AC pressure test of cables, motors and other equipment whose insulation presents a large equivalent capacitance. Testing at 0.1 Hz instead of power frequency cuts the capacity the source has to deliver to roughly one five-hundredth, which is what makes a 4 kg controller and a 40 kg booster enough for work that would otherwise need a resonant set.

Three output frequencies are provided - 0.1 Hz, 0.05 Hz and 0.02 Hz - with load capability of 1.1 µF, 2.2 µF and 5.5 µF respectively, so longer or higher-capacitance specimens can be tested by dropping to the lower frequency. Boost, buck, measurement and protection all run automatically under microcomputer control, and the 50 kV peak rating suits cables and motors in the 10 – 15 kV class.

Product View

50kv Very Low AC Hipot Test Set Used for Generator

Who This Set Is For

This rating is bought by teams whose test list is dominated by medium-voltage cable and machine insulation.

Cable maintenance crews testing 10 kV and 15 kV XLPE feeders after jointing, repair or a fault location.

Industrial plant electrical departments that pressure-test motors and generators during a shutdown rather than send them out.

Commissioning contractors who need one portable set that reaches 50 kV peak and can be carried between switch rooms.

The specimen capacitance has to stay within 1.1 µF at 0.1 Hz; above that the test is run at 0.05 Hz or 0.02 Hz, where the same set carries 2.2 µF and 5.5 µF.

Key Features

50 kV peak output in a two-piece set: 4 kg controller and 40 kg booster, with a 15 A supply fuse.

Three selectable frequencies - 0.1 Hz, 0.05 Hz and 0.02 Hz - with load capability of 1.1 µF, 2.2 µF and 5.5 µF.

Digital frequency conversion with microcomputer control, so boost, buck, measurement and protection are fully automatic.

Multiple protection including over-voltage and over-current on both the high and low voltage sides, acting within 10 ms.

Closed-loop negative feedback on the high and low voltage sides, which removes the capacitance-rise effect on the output.

Colour touch screen with liquid crystal display, automatic storage and automatic printout of test records.

Chinese and English interface switching, and operation from a portable generator of more than 3 kW with a stable 220 V / 50 Hz output.

Frequently Asked Questions

Q1.How much capacitance can the XHDP-50 carry?

1.1 µF at 0.1 Hz, 2.2 µF at 0.05 Hz and 5.5 µF at 0.02 Hz. If the specimen is smaller than 0.05 µF the output waveform suffers, and a 0.05 µF capacitor is connected in parallel to restore a clean output.

Q2.What supply does it need in the field?

220 V ± 5 %, 50 Hz ± 5 Hz. When a portable generator is used it should be rated above 3 kW and hold a stable 220 V / 50 Hz output, otherwise the boost process becomes unstable.

Q3.How is the right test voltage chosen for a 10 kV cable?

The rated 50 kV peak covers the 10 – 15 kV class with margin; the actual test voltage and duration follow the standard applied on site, and the set is programmed to that value before the run.

Q4.What happens if the specimen breaks down during the test?

Protection acts within 10 ms. Over-voltage and over-current protection on both the high and low voltage sides trips the output, so the breakdown is cleared before it can damage the booster.

Q5.Why does the reading not rise as capacitance is added?

The high and low voltage sides are closed-loop negative feedback controlled, which cancels the capacitance-rise effect that open-loop VLF sets show on large specimens.

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.
