Compare 2.0
Single-pole phase comparator
The phase comparator Compare 2.0 is a single-pole, capacitive phase comparator for voltages from 5 — 36 kV. The device detects “correct phase relationship” or “incorrect phase relationship” conditions between two live conductors of a medium voltage distribution network. Confirming to IEC 61481 Class B, “incorrect phase relationship” appears at a phase angle between 60° and 300°.
Four bright LEDs indicate various operational conditions.
The turning knob is used to select between three voltage ranges
1: 5 – 10 kV
2: 10 – 20 kV
3: 20 – 36 kV
The phase comparison is realised by contacting the conductors one after the other.
In medium voltage networks with decentralised renewable energy feed-ins, measurement interruptions may occur. In such cases, repeat the phase comparison. It is impossible to get a wrong indication.
According to the German accident prevention standard DGUV Regulation 3 (Table 1c), the device is subject to maintenance tests with minimum intervals of at least 6 years.
