PTE-30-CH Catalogue

Product catalog summary

Description: The document describes a chronometer designed as an accessory for injection instruments to test protective relays. Its primary function is to measure the delay time reaction of a protection relay in response to a trip condition.

Applications: The chronometer is used to measure the trip time in protection relays and the duration of a signal pulse.

Operation: The device features various function modes selectable via a MODE button, allowing it to operate in Frequency or Timer mode. It uses LEDs to indicate the type of signal at the input taps for starting and stopping the timer. The chronometer can start and stop based on circuit conditions (open/closed or presence/absence of voltage).

Control: The chronometer has three groups of press button switches: MODE (to change function modes), DISPLAY (to toggle between seconds or cycles), and RESET (to reset the timer or deactivate it).

Standard Accessories: Includes an instruction manual, connection cables, crocodile clips, a set of fuses, and a nylon protection bag.
