This National Standard of Canada is based on International Standard CEI/IEC 61243-2. This part of CAN/ULC-61243 is applicable to portable voltage detectors with or without a built-in power source to be used on electrical systems for voltages of 1 kV to 36 kV a.c., and frequencies from 15 Hz to 60 Hz. This part applies only to resistive voltage detectors used in contact with the part to be tested, as a single unit or as a separate device completed by an adaptable insulating pole covered in CAN/ULC-60855 or CAN/ULC-61235. Capacitive voltage detectors are covered in CAN/ULC-61243-1. The upper voltage limit is in accordance with the tests described in this part of CAN/ULC-61243.
