Product Overview
PG II — Two-pole Phase Comparator
The PG II is a two-pole phase comparator from HORSTMANN for determining phase equality between two live conductors in medium-voltage networks. The system consists of part A, an operating rod with an integrated contact electrode and display unit, and part B, a separate operating rod with a contact electrode for recording the reference value. The insulating rod can be separated from the display unit for safe handling and space-saving transport. The contact electrodes A and B are connected by a spiral, high-voltage-resistant cable designed for medium-voltage use. The unit is intended for indoor use in dry conditions and uses visual indication via three red LEDs to show phase status. The PG II is designed in accordance with IEC 61481-2:2014 and is subject to mandatory retesting every 6 years according to DGUV regulation 3 (table 1c).Typical Applications
- Determination of phase equality between two live conductors in medium-voltage networks.
- Use in switchgear rooms and network areas where clear phase responsibility must be established.
