PG II — Two-Pole Phase Comparator
Product Overview
The PG II from HORSTMANN is a two-pole phase comparator used for determining phase equality between two live conductors in medium-voltage networks. The system consists of two components: Part A, with an operating stick that integrates the contact electrode and display unit, and Part B, a separate operating stick with a contact electrode for reference measurement. The contact electrodes are connected by a coiled, high-voltage resistant cable, and the insulating stick can be separated from the display unit for transport.Technical Characteristics
- Two-pole phase comparator with optical display (3 red LEDs).
- Calculated operating conditions: dry conditions, usually indoors.
- Nominal frequency: 50 Hz (optional 60 Hz).
- Maximum operating time under voltage: 60 s.
- Connection cable between electrodes: 1 m (coiled, high-voltage resistant).
- Operating class B (display of phase imbalance in the range 60°–300°).
- Operating temperature: -25 °C to +70 °C; climatic class N and W.
Typical Applications
- Used to ascertain whether two live conductors have the correct phase relationship in a medium-voltage network.
- Suitable for use in switchgear and network areas where unambiguous phase assignment is necessary.
The version with article number 51-0102-010 is specified for a voltage range of 5–10 kV with a total length of 1,220 mm and an immersion depth of 413 mm. The PG II complies with IEC 61481-2:2014 and is subject to mandatory re-testing every 6 years according to DGUV Regulation 3.
