Description
Caltech India offers Solid-State Polarization Cell PPC1 and PPC2 Models.
PPC1 and PPC2 models
Caltech Engineering Services- India introduces, Pa-El’s Solid state polarization cell is semiconductor cell used for short-term current peaks and over voltage drainage. It is also used for synchronization of cathodic protection system with lightning strike protection demands for gas reduction station, measuring reduction station, blockade station etc.
There are two types of solid-state polarization cells; PPC1 for 35A/40kA current and PPC2 for 100A/40kA current.
Specification:
PPC1

| Mass | 6.33Kg |
Technical Data:
PPC1
| long-term current(AC/DC) | 35A |
| lightning surge current | 40kA(8/20S) |
| short-term fault current(AC) | 90A/0,5s |
| voltage blocking level (DC) | -3/+1V,-2/+2 V or according to customer |
| working temperature | -40°C to +60°C |
PPC2
| long-term current(AC/DC) | 100A |
| lightning surge current | 40kA(8/20S) |
| short-term fault current(AC) | 700A/0,5s |
| voltage blocking level (DC) | -3/+1V,-2/+2 V or according to customer |
| working temperature | -40°C to +60°C |
It is possible to install current and voltage measuring sensor switch characteristics as follows:
PPC1
| current sensors(shunt) | 60mV/40A |
| voltage sensor | -10V,+10V |
PPC2
| current sensors(shunt) | 60mV/100A |
| voltage sensor | -10V,+10V |
Voltage and current signals are available on DB9 standard connector.
Adjustment and Repair:
Validity check is performed once a year. Validity check is performed by:
- visual inspection
- blocking voltage check in both direction
- measuring point cable check
- grounding resistance measurement
- AC/DC potential on pipeline and grounding measurement
- AC/DC current measurement.
PPC is a one-time product and adjustment is not possible. Breakdown voltage is mostly occurred as short-circuit, rarely as a total disconnection between positive and negative pole. If break down detected it is necessary to replace cell with new one.
