  • InsuLogix® HMA | Hydrogen, Moisture, and Acetylene
    The InsuLogix® HMA is a state-of-the-art, high-performance online monitor for incipient fault detection and monitoring in power transformers via measuring the levels and the rising of Hydrogen (H2) and Acetylene (C2H2)....


    • Detects and alerts on hydrogen and acetylene presence in oil, as well as on rising levels of the two gasses

    • Hydrogen and acetylene monitoring represent the best cost/benefits ratio in transformer monitoring strategies

    • Promotes for Condition Based Maintenance

    • Reduces risk of catastrophic failure

    • Simple set up and operation

    • Moisture in oil measurement available in standard configuration

    • Resistant to vacuum

    • Low ownership cost


    • Laser and thermal conductivity sensing technologies

    • Color-changing LED on front panel for visual indication of alarms status

    • LCD screen on front panel for indication of the gasses and moisture concentrations, monitor status and alarms

    • System watchdog function

  • INSULutions® DPE
    Advanced cellulose based insulating paper for up to 140 °c thermal class in liquid-immersed transformers....

  • INSULutions DPE (DPE - Diamond Printed Enhanced) is a new generation, cellulose based insulating paper from Weidmann, engineered to exceed the performance of traditional Kraft papers used for layer insulation in transformers: increased thermal rating; accelerated drying and liquid impregnation rates; better dielectric performance; and excellent mechanical strength. The cost of DPE paper is a fraction of the cost of non-cellulose papers making DPE the most cost effective option for insulation in standard and higher thermal rating liquid-immersed transformers, both in mineral oil and ester liquid. 

  • InsuLogix® SSK Safe Sampling Kit
    Simplifying oil sampling in oil filled pad mount transformers and switchgear, reducing cost, increasing safety, and ensuring maximum uptime of assets without the need for de-energizing....

  • Taking an oil sample for analysis purposes from critical energy assets is an important piece in any maintenance plan. The InsuLogix® SSK is a patented device that enables fast, safe, and reliable access to retrieve oil samples without the need to open the high voltage equipment cabinet.

    Safe | Efficient | Economical
    •    Field operators can collect oil in safer conditions – typically 12x faster
    •    The cost effective InsuLogix® SSK provides a rapid return on investment (cost saving)
    •    High voltage equipment will NOT have to be de-energized before taking an oil sample
    •    Continue to supply energy into the system during the entire oil collection operation
    •    Better asset utilization means more revenue for your organization

    The patented design differentiates InsuLogix® SSK
    The Weidmann InsuLogix® SSK is installed inside of the high voltage equipment cabinet in as little as 30 minutes and includes a full installation kit. The device provides safe, easy, and simple access from outside, with no requirement to open the high voltage equipment cabinet. 

    Tip: Similar devices that are installed on the outside of high voltage equipment cabinets increase the risk of failure due to accidental damage (stepping on, impact with other equipment etc.) and exposure to the environment.
