AC Variable-Frequency Resonance Test Systems, tank-type up to 100 kV

Overview

AC variable-frequency resonance test systems in tank-type configuration, rated for applications up to 100 kV. Variable-frequency operation covers the IEC-recommended band of 20 to 300 Hz, with example frequency denotation shown as [20] -30..300 in model data. Duty cycle: 1 hour on / 1 hour off, 6 cycles per 24 hours. Three representative model configurations are listed with their tap capacitance, frequency range and physical sizes: VRTS8TC60-300 — Tap 1 kV [µf]: 60 [0.44]; Tap 2 kV [µf]: 24 [2.76]; Tap 3 kV [µf]: 12 [11.0]; Frequency Range [Hz]: [20] -30..300; Dimensions LxWxH (mm): 1200 x 1200 x 1350; Weight (kg): 1800. VRTS8TC50-1000 — Tap 1 kV [µf]: 50 [2.12]; Tap 2 kV [µf]: 25 [10.6]; Frequency Range [Hz]: [20] -30..300; Dimensions LxWxH (mm): 2200 x 1270 x 1620; Weight (kg): 4200. VRTS8TC100-1000 — Tap 1 kV [µf]: 100 [2.12]; Tap 2 kV [µf]: 50 [10.6]; Frequency Range [Hz]: [20] -30..300; Dimensions LxWxH (mm): 2300 x 1270 x 1620; Weight (kg): 4800. Power supply and control enclosure package dimensions and weights are listed separately: Power Supply — Length: 85 (2159) | Width: 38 (965) | Height: 80 (2032) | Weight: 3200 (1451). Control Enclosure — Length: 22 (559) | Width: 22 (559) | Height: 20 (508) | Weight: 50 (23). Rated-value examples for the broader product family span from 15 kV to over 2 million volts at 50 or 60 Hz, indicating the platform is part of a larger range of high-voltage test systems. Designed for industrial high-voltage resonance testing in manufacturing, commissioning and laboratory environments where controlled variable-frequency AC excitation is required. The tank-type form factor supports tests that require a contained test assembly (tank-mounted test objects), and the available tap capacitances provide selectable test capacitance options for matching resonance conditions. Model selection is driven by required test voltage and capacitance taps, available floor space and weight handling: smaller units (example VRTS8TC60-300) have a more compact footprint and lower mass; larger 1000-series models provide higher mass and larger physical footprint for higher-energy tests. The 1 hour on / 1 hour off duty cycle and the 20–300 Hz variable-frequency capability should be used to plan test schedules and thermal duty requirements during production acceptance, type testing or R&D validation of high-voltage components and assemblies.
