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 Alarm.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.
