Refrigerator Compressor 3 Different Way Connect current Relay PTC
Then at start, with PTC in series: If Zaux is low impedance, less than 10 % of RPTC then it can be ignored and IPTC at start = This closely approximates the condition for motors over 1/2 HP Fig. T-5 Fig T-6 Simplified voltage diagram of the PSC motor at operatingPTC speed. Note (1) I A (auxiliary current) leads I M (main current) by 80° to 90.

With the start capacitor we connect the ptc relay thermistor in series, which eliminates the start capacitor in the circuit. In many relay PTC compressor has a connection point for the operating capacitor and connect the capacitor in parallel with the relay, which helps better performance and compressor. ptc relay working principle, ptc relay.

A PTC relay uses a positive temperature coefficient thermistor to remove the start winding and/or start capacitor from the circuit. A PTC thermistor is basically a resistor whose resistance increases on an increase in temperature. The circuit is wired so that the PTC thermistor is wired in series with the start winding of the motor (Fig. 1).
PTC Heater Relay
If the reading on the multimeter is between 0 and 1 ohms, the relay is in good working condition. If the reading exceeds 1 ohm, replace the PTC relay. In other words, the relay should read O.L or 0 to 1 ohm. Before testing the relay, clean the device and all its sports to remove dust. Dust may interfere with the resistance reading, throwing it off.
Threephase asynchronous motor PTC protection circuits under Motor
Set your multimeter to read resistance in ohms (Ω) so you can easily test the PTC relay. Plug the end of the red probe into the positive (+) terminal and the black probe into the negative (-) terminal on the bottom of the multimeter so you can use them. [8] You can buy a multimeter from a hardware store or online. 3.

The circuit diagram below shows an example of an inrush current limiter (ICL) circuit, in which a PTC thermistor and a thyristor (or a mechanical relay) are used in combination. When the power switch is closed and the charging process starts, the uncharged capacitor is like a short circuit and therefore draws a very high inrush current.

Ptc Relay Wiring Diagram
The PTC (positive temperature coefficient) relay is directly connected in series with the secondary winding (start winding) and in parallel with the main winding of the motor. When AC 220V is applied to the two windings, a phase difference will be generated due to phase separation, thus forming an elliptical rotating magnetic field and generating a starting torque to drive the normal operation.
