Understanding PZM Transformer Alerts
Transformers are the backbone of electrical infrastructure, and
ensuring their optimal performance is paramount. With PZM's
enterprise SaaS app, electric cooperatives gain a powerful ally
in transformer maintenance.
Low / High Nitrogen Alert:
This alert is because the transformer's nitrogen level is
outside the acceptable pressure range (PZM's default is 0.5-5
psi). This range provides a slight positive nitrogen pressure.
Nitrogen reduces the risk of a fire hazard and protects the
transformer oil and insulation from reacting with oxygen in
the air and deteriorating.
Associated Fields: Nitrogen High Alarm and Nitrogen Low
High Winding / Oil Temperatures:
This alert is because the transformer's winding or oil
temperature is above the set alarm point (PZM's default is
80C). High temperatures can indicate overloading, blocked
ventilation, faulty cooling fans or pumps, or internal faults.
Operating a transformer at high temperatures will shorten the
life and reduce the capacity rating.
Associated Fields: High Oil Temperature Alarm and High
Winding Temperature Alarm.
PZM Alert Types
Inspection Alerts instantly tell you what and
where inspections are past due or due within the next 7 days.
Deficiency Alerts tell you instantly what and
where your highest risk deficiencies are.
System Voltage Alerts instantly tell you
where the highest and lowest voltage levels are on your
transmission and distribution system.
Reg Ops Alerts tell you your most active
regulators on the system and enable you to prevent worn
contacts and premature failure of the regulator.
Breaker Ops Alerts identifies which breaker
or recloser is experiencing the most faults on the system, and
the user-defined impact of those faults, based on any
combination of meter counts, load at risk, or revenue at risk.
PZM Alerts are designed to get the most out of your inspection
program. We save hours and hours of grueling analysis and
deliver quality, actionable information that will improve your
utility's electrical system with a click of a button.
