ISOLOMETRO Terex

Isolometro is a portable insulator tester enabling linemen to quickly detect a malfunctioning insulator of an insulator string on energized distribution and transmission systems. The working principle is based on the measurement of the potential difference through the insulator disc under test. A high impedance galvanometer indicates this potential difference, enabling the comparison with other insulator discs of the same system.

Therefore, the reading on the faulty insulator disc will be considerably bottom than on the others.

The Isolometro may be used to evaluate pin insulators, single insulators, multipart pin type insulators and disc insulators.

Composed of fiberglass poles and housing with contact probes that can be easily adjusted to various positions, enabling the test of insulators of any sizes, and also providing adjustments for a better view angle.

Isolometro features a 3-position switch to adjust its sensitivity so a more adequate probe deflection is obtained.

The Calibration Device is intended to check the Isolometro prior to use, mainly after an extended period of no service.

The calibration device sends a digital signal to the Isolometro so the reading on the galvanometer can be compared with the value indicated on the display of the Calibration Device.

The Calibration Device must be ordered separately.

The set is composed of the tester, case and user guide.
