PTS175 MV Advanced Analyzer 4
Chapter 1 General Information
The LINDSEY MV Line Post Sensors (or also known as Pole Top Sensor –
PTS) replace standard MV line insulators and incorporate a built-in CT and
PT like.
The PTS converts the high voltage and current to a small voltage signal
instead of the normal 120 Volt and 5 Amp outputs of standard CTs and
PTs. Based on SATEC Model PM175-LSY Power Quality / Energy Meter to
fully interface with the low level sensor outputs for line voltage and
current. Full measurements and data can be obtained from the PM175,
including waveforms and harmonics. The PTS175 consisting of a robust
plastic enclosure incorporating the PM175, HV protected input connections
and a GPRS modem providing real-time data communication to a
customer Monitoring System, makes installation easy and simple.
The PTS175 covers three Medium Voltage ranges: 11kV, 22kV and 33kV.
Each range represents a PTS175 model:
 PTS175-15KV 1 – for 11kV (L-L) distribution lines
 PTS175-25KV 1 – for 22kV (L-L) distribution lines
 PTS175-35KV 1 – for 33kV (L-L) distribution lines
Refer to PM175 Installation and Operation Manual (BG0415 REV.A7), for
device setup and monitoring
Note 1 : The PM175 meter in the PTS175 MV Advanced Analyzer is factory
setup as follows:

 CT Primary current (A): 300
 PT ratio:
– For 15kV: 22.5
– For 25kV:
53.1
– For 35kV:
160.9
 PT multiplier: x1
