The Herculito is a lightweight and compact 100-Amperes DC micro-ohmmeter. The meter is designed to test EHV circuit-breaker contact resistance, bushing contact joints or for performing any low-resistance measurement. Using the latest switching power supply technology, the Herculito merely weighs 18 lbs (8 kg) and is housed in a 17"W x 7"H x 13"D (43 cm x 18 cm x 33 cm) watertight, high impact, plastic case. The Herculito's power supply is thermally protected.
The microprocessor-based Herculito can accurately measure resistances ranging from 1 micro-ohm to 20 milli-ohms. The resistance reading is displayed directly in micro-ohms or milli-ohms. No calculations are required to compensate for the test lead resistances when using the Herculito.
The Herculito features a back-lit LCD screen (16 characters by 2 lines) that is viewable in both bright sunlight and low-light levels. The last three measurements are stored internally and can be displayed on the LCD screen. An RS-232C interface port is also provided for diagnostic testing.
The Herculito is furnished with two 40-foot test cables that include quickconnect test leads. Voltage-sensing leads are built into the cable and carry no load current, thus the true voltage is measured at the contacts. Heavy-duty, welding-type, C-clamps are available as an accessory. These can be used to connect the test-cable leads to a wide variety of bushing sizes, bus-bars and other conductors.
