The ZSI signalling cable between the circuit breakers produces a signal from Q3, which informs Q2 that the downstream circuit breaker has detected the fault. -
Page 56: Zone Interlocking With Tempower 2 Acbs
Protection Settings Zone Selective Interlocking Function (ZSI) Zone Interlocking with TemPower 2 ACBs With TemPower 2 ACBs ZSI is available as a custom feature and is designed differently to P_SE ZSI. With these differences it is still possible to zone interlock TemPower 2 with TemBreak PRO P_SE, there are just a few considerations that need to be respected. - Page 57 Protection Settings Zone Selective Interlocking Function (ZSI) Zone Interlocking with TemPower 2 ACBs Wiring Requirements There is no limit to the number of interconnected upstream and downstream circuit breakers using the ZSI signalling interface; however, the reliability of the ZSI signal is dependent on the total impedance of the interconnecting cables. Therefore, the total impedance of the ZSI signalling cables and intermediate wiring and terminations must be considered.
- Page 58 Protection Settings Zone Selective Interlocking Function (ZSI) Zone Interlocking with TemPower 2 ACBs Power Requirements For continuous ZSI operation, 24VDC should be supplied to the P_SE Trip Unit externally. While ZSI signalling can work without external 24VDC supply via the CIP port on P_SE MCCB’s, it relies on the MCCB contacts being closed and conducting sufficient current to provide the minimum requirements for self- power.

Page 71: Total Harmonic Distortion (Thd)
Measurement and Settings Total Harmonic Distortion (THD) The P_SE Trip Unit calculates the total harmonic distortion levels from the real-time current and voltage measurements (every second). These calculations are performed up to the 31st harmonic. The total harmonic distortion levels may be used to indicate load or power supply quality according to the purity of the current and/or voltage waveform, where low level of wave distortion is ideal. -
Page 72: Demand Values (Averaged Values Over An Interval)
Measurement and Settings Demand Values (averaged values over an interval) The P_SE Trip Unit calculates the averaged current and power values by integration over a specified time interval. These are the Demand values or the averaged values over an interval. Demand values are useful in order to create a load profile for the loads supplied by the P_SE MCCB. Demand values are distinct and not to be confused with other instantaneous average measurements (e.g. -
Page 73: Demand Mode

Page 75: Energy Measurements
Measurement and Settings Energy Measurements The P_SE Trip Unit provides various energy readings by integrating the instantaneous power over a network period and storing the totalised energy in several counters and incremented once every second. Active and reactive energy counters provide separate and combined values for produced and consumed energy (i.e. energy flowing through the MCCB in either direction). -
Page 76: Alarms
Alarms Alarm Types The P_SE Trip Unit provides alarming for various types of events based on system status and live monitoring of parameters. There are four types of alarms based on functionality and configurability: System alarm: Correspond to predefined events internal to the Trip Unit. Pre-Trip alarm (PTA): Provides a warning about the imminent trip risk due to a current overload. -
Page 77: Priority Level
Alarms Priority Level Each trip and custom alarm is associated with it a priority level, which determines how each alarm is displayed and logged. Notice: Custom alarms are only visible using the TVP or TPCM, however, the P_SE Trip Unit will still monitor and log any prior configured alarms without either TVP or TPCM connected. -
