ULC 61243-1 – Live working — Voltage detectors — Part 1: Capacitive type to be used for voltages exceeding 1kV a.c. (CAN/ULC 61243-1)

This part of the CAN/ULC-61243 series is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 765 kV a.c., and frequencies of 50 Hz and/or 60 Hz. This part applies only to voltage detectors of capacitive type used in contact with the part to be tested, as a complete device including its insulating element or as a separate device, adaptable to an insulating stick which, as a separate tool, is not covered by this standard

Other types of voltage detectors are not covered by this part of the standard.

NOTE Except where otherwise specified, all the voltages defined in this standard refer to values of phase-to phase voltages of three-phase systems. In other systems, the applicable phase-to-phase or phase-to-earth (ground) voltages should be used to determine the operating voltage.
