Voltage measuring converter series IPN-05 UHL3.1
The voltage measuring converter series IPN-05 UHL3.1 is intended to replace voltage transformers (VT) class 6-35 kV, which are used in measuring circuits for electricity metering with an accuracy class of 0.5.
IPN-05 UHL3.1 includes a transducer block in a metal case, with a resistive carry electrode installed (in form of an insulator unit). This contains a power supply and an amplifier.
IPN-05 UHL3.1 is designed as a linear amplifier of a weak signal coming from a resistive carry electrode relative to the housing. The output signal can be also removed relative to the housing. The amplifier has a current limit.
The converter has a 1.5 kV galvanic isolation between measuring circuits and an auxiliary power source.
Advantages of IPN-05 UHL3.1:
- lower cost, weight and dimensions compared to VT;
- absence of resonance and saturation which can occur in VT;
- reliable performance in networks with large voltage surges, high percentage of harmonics, for example, in contact network of Russian Railways;
Carry electrode is made in the form of an insulator unit class 6-35 kV.
