Model 250 Parabolic Pinpointer
Portable Fault Detectors for Substation and OH Line Assets
- Compact
- Sensitive
- Precise
T he Model 250 Ultrasonic Detector was designed specifically for pinpointing sources of powerline sparking and corona. It is a one piece instrument that includes an ultrasonic sensor, parabolic reflector, and receiver. The Model 250 may be used by field personnel from the ground or from a bucket. The operator of the Model 250 identifies the
specific hardware that is sparking by aiming through the sight, observing the signal strength meter, and listening to the speaker. The instrument is very directional and sensitive to powerline noise. Unique circuitry aids the operator in
distinguishing powerline sparking from background noise. The Model 250 is a line of sight instrument that compliments other RFI locators.
