Impulse generator T3-61

Inmtroduction

T3-61 1,2/50 IMPULSE GENERATOR is intended for performing dielectric tests with impulse voltage on low-voltage equipment. It creates impulses with a virtual front time of 1,2 µs and a virtual time to half-value of 50 µs. Samples are tested by (high) voltage surges.

It is constructed in compliance with the following standards:

IEC 60335-1: Household and similar electrical appliances – Safety – Part 1: General requirements: Clause 14 Transient overvoltages

IEC 60950-1: Information technology equipment – Safety – Part 1: General requirements: Annex N: Impulse test generators

IEC 61180-1: High-voltage test techniques for low-voltage equipment; Part 1: Definitions, test and procedure requirements

IEC 61180-2 High-voltage test techniques for low-voltage equipment - Part 2: Test equipment

We designed IMPULSE GENERATOR with the following goals:

• Safety
• Reliability
• Ease of operation
• Ergonomical design

Main Features

• Ergonomically designed.
• Transparent acrylic 10 mm thick door and side panels enable observing of tested sample during the test, and protection of operator in case that due to the energy released during a surge a sample bursts (small explosion)
• Test cabinet bottom is 20 mm thick
• Two voltage generators – separate for each polarity
• High voltage switching systems with electromagnets for better safety
• Two door safety protection switches – surge can only be applied when doors are closed
• V-meter enables observing and adjusting surge voltage
• Internal voltage divider 10:1 with outside BNC (to connect a oscilloscope with HV probe)
• HV oscilloscope probe
• Variable ratio transformer with knob for voltage adjustment 400 – 12 000 V DC
• Push button CHARGE + for positive charging polarity
• Push button CHARGE - for negative charging polarity
• Illuminated push button DISCHARGE for activating the surge
• Mains switch with fuse
• Anodized aluminum front plate, with inscriptions that clearly explain the function of each component on the front plate
• Sample connection terminal sockets are located inside insulated protecting test cabinet
• Two port holes, with plugs, for possibility of connecting bigger samples in external test cabinets
• Auto‑detect connector, for connecting external door (protection) switch if customer uses other/bigger external test cabinet
